Self type: `object`.type

style - This attribute defines the styling language as a MIME type (charset should not be specified). This attribute is optional and defaults to text/css if it's missing. object - The content type of the resource specified by data. At least one of data and type must be defined. li - This character attribute indicates the numbering type:

a: lowercase letters
A: uppercase letters
i: lowercase Roman numerals
I: uppercase Roman numerals
1: numbers This type overrides the one used by its parent <ol> element, if any.

Usage note: This attribute has been deprecated: use the CSS list-style-type property instead. param - Only used if the valuetype is set to "ref". Specifies the MIME type of values found at the URI specified by value. source - The MIME-type of the resource, optionally with a codecs parameter. See RFC 4281 for information about how to specify codecs. button - The type of the button. Possible values are:

submit: The button submits the form data to the server. This is the default if the attribute is not specified, or if the attribute is dynamically changed to an empty or invalid value.
reset: The button resets all the controls to their initial values.
button: The button has no default behavior. It can have client-side scripts associated with the element's events, which are triggered when the events occur. script -

Indicates the type of script represented. The value of this attribute will be in one of the following categories:

Omitted or a JavaScript MIME type: For HTML5-compliant browsers this indicates the script is JavaScript. HTML5 spec urges authors to omit the attribute rather than provided a redundant MIME type. In earlier browsers, this identified the scripting language of the embedded or imported (via the src attribute) code. JavaScript MIME types are listed in the specification.
module: HTML5 For HTML5-compliant browsers the code is treated as a JavaScript module. Processing of the script contents are not affected by the charset and defer attributes. For information on using module, see ES6 in Depth: Modules.
Any other value or MIME type: Embedded content is treated as a data block which won't be processed by the browser. The src attribute will be ignored.

Note that in Firefox you can use advanced features such as let statements and other features in later JS versions, by using type=application/javascript;version=1.8 . Beware, however, that as this is a non-standard feature, this will most likely break support for other browsers, in particular Chromium-based browsers.

For how to include exotic programming languages, read about Rosetta. link - This attribute is used to define the type of the content linked to. The value of the attribute should be a MIME type such as text/html, text/css, and so on. The common use of this attribute is to define the type of style sheet linked and the most common current value is text/css, which indicates a Cascading Style Sheet format. It is also used on rel="preload" link types, to make sure the browser only downloads file types that it supports. embed - The MIME type to use to select the plug-in to instantiate. ul - Used to set the bullet style for the list. The values defined under HTML3.2 and the transitional version of HTML 4.0/4.01 are:

circle,
disc,
and square.

A fourth bullet type has been defined in the WebTV interface, but not all browsers support it: triangle.

If not present and if no CSS list-style-type property does apply to the element, the user agent decide to use a kind of bullets depending on the nesting level of the list.

Usage note: Do not use this attribute, as it has been deprecated; use the CSS list-style-type property instead. a - Specifies the media type in the form of a MIME type for the linked URL. It is purely advisory, with no built-in functionality. input - The type of control to render. See Form <input> types for the individual types, with links to more information about each. area - This attribute specifies the media type in the form of a MIME type for the link target. Generally, this is provided strictly as advisory information; however, in the future a browser might add a small icon for multimedia types. For example, a browser might add a small speaker icon when type is set to audio/wav. For a complete list of recognized MIME types, see https://www.w3.org/TR/html4/references.html#ref-MIMETYPES. Use this attribute only if the href attribute is present. ol - Indicates the numbering type:

'a' indicates lowercase letters,
'A' indicates uppercase letters,
'i' indicates lowercase Roman numerals,
'I' indicates uppercase Roman numerals,
and '1' indicates numbers (default).

The type set is used for the entire list unless a different type attribute is used within an enclosed <a title="The HTML

element is used to represent an item in a list. It must be contained in a parent element: an ordered list (), an unordered list (), or a menu (). In menus and unordered lists, list items are usually displayed using bullet points. In ordered lists, they are usually displayed with an ascending counter on the left, such as a number or letter." href="/en-US/docs/Web/HTML/Element/li"><li> element.

Note: This attribute was deprecated in HTML4, but reintroduced in HTML5. Unless the value of the list number matters (e.g. in legal or technical documents where items are to be referenced by their number/letter), the CSS list-style-type property should be used instead. menu - This attribute indicates the kind of menu being declared, and can be one of two values.

context: Indicates the popup menu state, which represents a group of commands activated through another element. This might be as a button menu referenced by a menu attribute of a <button> element, or as context menu for an element with a contextmenu attribute. This value is the default if the attribute is missing and the parent element is also a <menu> element.
toolbar: Indicates the toolbar state, which represents a toolbar consisting of a series of commands for user interaction. This might be in the form of an unordered list of <a title="The HTML

This value is the default if the attribute is missing. menuitem - This attribute indicates the kind of command, and can be one of three values.

form - A comma-separated list of content types that the server accepts.

Usage note: This attribute has been removed in HTML5 and should no longer be used. Instead, use the accept attribute of the specific <input> element. input - If the value of the type attribute is file, then this attribute will indicate the types of files that the server accepts, otherwise it will be ignored. The value must be a comma-separated list of unique content type specifiers:

A file extension starting with the STOP character (U+002E). (e.g. .jpg, .png, .doc).

img - This attribute defines the alternative text describing the image. Users will see this text displayed if the image URL is wrong, the image is not in one of the supported formats, or if the image is not yet downloaded.

Browsers do not always display the image referenced by the element. This is the case for non-graphical browsers (including those used by people with vision impairments), if the user chooses not to display images, or if the browser cannot display the image because it is invalid or an unsupported type. In these cases, the browser may replace the image with the text defined in this element's alt attribute. You should, for these reasons and others, provide a useful value for alt whenever possible.

Omitting this attribute altogether indicates that the image is a key part of the content, and no textual equivalent is available. Setting this attribute to an empty string (alt="") indicates that this image is not a key part of the content, and that non-visual browsers may omit it from rendering. area - A text string alternative to display on browsers that do not display images. The text should be phrased so that it presents the user with the same kind of choice as the image would offer when displayed without the alternative text. In HTML4, this attribute is required, but may be the empty string (""). In HTML5, this attribute is required only if the href attribute is used.

option - If this Boolean attribute is set, this option is not checkable. Often browsers grey out such control and it won't receive any browsing event, like mouse clicks or focus-related ones. If this attribute is not set, the element can still be disabled if one of its ancestors is a disabled <optgroup> element. textarea - This Boolean attribute indicates that the user cannot interact with the control. (If this attribute is not specified, the control inherits its setting from the containing element, for example <fieldset>; if there is no containing element with the disabled attribute set, then the control is enabled.) menuitem - Boolean attribute which indicates that the command is not available in the current state. Note that disabled is distinct from hidden; the disabled attribute is appropriate in any context where a change in circumstances might render the command relevant. link - This attribute is used to disable a link relationship. In conjunction with scripting, this attribute could be used to turn on and off various style sheet relationships.

Note: While there is no disabled attribute in the HTML standard, there is a disabled attribute on the HTMLLinkElement DOM object.

The use of disabled as an HTML attribute is non-standard and only used by some browsers (W3 #27677). Do not use it. To achieve a similar effect, use one of the following techniques:

If the disabled attribute has been added directly to the element on the page, do not include the <link> element instead;
Set the disabled property of the StyleSheet DOM object via scripting. keygen - This Boolean attribute indicates that the form control is not available for interaction. fieldset - If this Boolean attribute is set, the form controls that are its descendants, except descendants of its first optional <legend> element, are disabled, i.e., not editable. They won't receive any browsing events, like mouse clicks or focus-related ones. Often browsers display such controls as gray. optgroup - If this Boolean attribute is set, none of the items in this option group is selectable. Often browsers grey out such control and it won't receive any browsing events, like mouse clicks or focus-related ones. select - This Boolean attribute indicates that the user cannot interact with the control. If this attribute is not specified, the control inherits its setting from the containing element, for example fieldset; if there is no containing element with the disabled attribute set, then the control is enabled. input -

This Boolean attribute indicates that the form control is not available for interaction. In particular, the click event will not be dispatched on disabled controls. Also, a disabled control's value isn't submitted with the form.

Unlike other browsers, Firefox will by default persist the dynamic disabled state of an <input> across page loads. Use the autocomplete attribute to control this feature. button -

This Boolean attribute indicates that the user cannot interact with the button. If this attribute is not specified, the button inherits its setting from the containing element, for example <fieldset>; if there is no containing element with the disabled attribute set, then the button is enabled.

Firefox will, unlike other browsers, by default, persist the dynamic disabled state of a <button> across page loads. Use the autocomplete attribute to control this feature.

area - This attribute, if present, indicates that the author intends the hyperlink to be used for downloading a resource. See <a> for a full description of the download attribute. a - This attribute instructs browsers to download a URL instead of navigating to it, so the user will be prompted to save it as a local file. If the attribute has a value, it is used as the pre-filled file name in the Save prompt (the user can still change the file name if they want). There are no restrictions on allowed values, though / and </code> are converted to underscores. Most file systems limit some punctuation in file names, and browsers will adjust the suggested name accordingly.

Notes:

This attribute only works for same-origin URLs.
This attribute can be used with blob: URLs and data: URLs to download content generated by JavaScript, such as pictures created in an image-editor Web app.
If the HTTP header Content-Disposition: gives a different filename than this attribute, the HTTP header takes priority over this attribute.
If Content-Disposition: is set to inline, Firefox prioritizes Content-Disposition, like the filename case, while Chrome prioritizes the download attribute.

keygen - The form element that this element is associated with (its form owner). The value of the attribute must be an id of a <form> element in the same document. If this attribute is not specified, this element must be a descendant of a <form> element. This attribute enables you to place <keygen> elements anywhere within a document, not just as descendants of their form elements.
meter - This attribute associates the element with a form element that has ownership of the meter element. For example, a meter might be displaying a range corresponding to an input element of type number. This attribute is only used if the meter element is being used as a form-associated element; even then, it may be omitted if the element appears as a descendant of a form element.
fieldset - This attribute has the value of the id attribute of the <form> element it's related to. Its default value is the id of the nearest <form> element it is a descendant of.

If the attribute contains an invalid value, it will use metadata. (Versions of Chrome earlier than 52 treated an invalid value as subtitles.) The following keywords are allowed:

subtitles
Subtitles provide translation of content that cannot be understood by the viewer. For example dialogue or text that is not English in an English language film.
Subtitles may contain additional content, usually extra background information. For example the text at the beginning of the Star Wars films, or the date, time, and location of a scene.
captions
Closed captions provide a transcription and possibly a translation of audio.
It may include important non-verbal information such as music cues or sound effects. It may indicate the cue's source (e.g. music, text, character).
Suitable for users who are deaf or when the sound is muted.
descriptions
Textual description of the video content.
Suitable for users who are blind or where the video cannot be seen.
chapters
Chapter titles are intended to be used when the user is navigating the media resource.

area - Define a names for the clickable area so that it can be scripted by older browsers.
textarea - The name of the control.
select - This attribute is used to specify the name of the control.
object - The name of valid browsing context (HTML5), or the name of the control (HTML 4).
meta -
This attribute defines the name of a piece of document-level metadata. It should not be set if one of the attributes itemprop, http-equiv or charset is also set.
This metadata name is associated with the value contained by the content attribute. The possible values for the name attribute are:


application-name defines the name of the application running in the web page.
Note:


Browsers may use this to identify the application. It is different from the <title> element, which usually contain the application name, but may also contain information like the document name or a status.


Simple web pages shouldn't define an application-name.


author defines the name of the document's author.


description contains a short and accurate summary of the content of the page. Several browsers, like Firefox and Opera, use this as the default description of bookmarked pages.


generator contains the identifier of the software that generated the page.


keywords contains words relevant to the page's content, separated by commas.


referrer   controls the Referer HTTP header attached to requests sent from the document:           Values for the     content attribute of     <meta name="referrer">                  no-referrer       Do not send a HTTP Referer header.      
           origin       Send the origin of the document.      
           no-referrer-when-downgrade       Send the origin as referrer to URLs as secure as the current page, (https→https), but don't send a referrer to less secure URLs (https→http). This is the default behavior.      
           origin-when-crossorigin       Send the full URL (stripped of parameters) for same-origin requests, but only send the origin for other cases.      
           unsafe-URL       Send the full URL (stripped of parameters) for same-origin or cross-origin requests.      
    
   


Some browsers support the deprecated values always, default, and never for referrer.


Dynamically inserting <meta name="referrer"> (with document.write or appendChild) makes referrer behavior unpredictable.


When several conflicting policies are defined, the no-referrer policy is applied.


The attribute may also have a value taken from the extended list defined on WHATWG Wiki MetaExtensions page. Although none have been formally accepted yet, a few commonly used names are:
Finally, a few names are in common use, though not in the process of being standardized:

creator defines the name of the creator of the document, such as an organization or institution. If there are more than one, several <meta> elements should be used.
googlebot, a synonym of robots, but is only followed by Googlebot, the indexing crawler for Google.
publisher defines the name of the document's publisher.
robots defines the behavior that cooperative crawlers, or "robots", should use with the page. It is a comma-separated list of the values below:           Values for the content of     <meta name="robots">                  Value       Description       Used by

           none       Equivalent to noindex, nofollow       Google      
           noodp       Prevents using the Open Directory Project description, if any, as the page description in search engine results.       

Google, Yahoo, Bing      
           noarchive       Requests the search engine not cache the page content.       Google, Yahoo, Bing      
           nosnippet       Prevents displaying any description of the page in search engine results.       Google, Bing      
           noimageindex       Requests this page not appear as the referring page of an indexed image.       Google      
           nocache       Synonym of noarchive.       Bing      
    
   

Notes:


Only cooperative robots follow these rules. Do not expect to prevent e-mail harvesters with them.


The robot still needs to access the page in order to read these rules. To prevent bandwidth consumption, use a robots.txt file.


If you want to remove a page, noindex will work, but only after the robot visits the page again. Ensure that the robots.txt file is not preventing revisits.


Some values are mutually exclusive, like index and noindex, or follow and nofollow. In these cases the robot's behavior is undefined and may vary between them.


Some crawler robots, like Google, Yahoo, and Bing, support the same values for the HTTP header X-Robot-Tags; this allows non-HTML documents like images to use these rules.


slurp, a synonym of robots, but only for Slurp, the crawler for Yahoo Search.

audio - This enumerated attribute is intended to provide a hint to the browser about what the author thinks will lead to the best user experience. It may have one of the following values:

none: indicates that the audio should not be preloaded;
metadata: indicates that only audio metadata (e.g. length) is fetched;
auto: indicates that the whole audio file could be downloaded, even if the user is not expected to use it;
the empty string: synonym of the auto value.

If not set, its default value is browser-defined (i.e. each browser may have its own default value). The spec advises it to be set to metadata.
Usage notes:

The autoplay attribute has precedence over preload. If autoplay is specified, the browser would obviously need to start downloading the audio for playback.
The browser is not forced by the specification to follow the value of this attribute; it is a mere hint.

If specified as an empty string, this attribute enables extra restrictions on the content that can appear in the inline frame. The value of the attribute can either be an empty string (all the restrictions are applied), or a space-separated list of tokens that lift particular restrictions. Valid tokens are:

allow-forms: Allows the embedded browsing context to submit forms. If this keyword is not used, this operation is not allowed.
allow-modals: Allows the embedded browsing context to open modal windows.
allow-orientation-lock: Allows the embedded browsing context to disable the ability to lock the screen orientation.
allow-pointer-lock: Allows the embedded browsing context to use the Pointer Lock API.
allow-popups: Allows popups (like from window.open, target="_blank", showModalDialog). If this keyword is not used, that functionality will silently fail.
allow-popups-to-escape-sandbox:  Allows a sandboxed document to open new windows without forcing the sandboxing flags upon them. This will allow, for example, a third-party advertisement to be safely sandboxed without forcing the same restrictions upon a landing page.
allow-presentation: Allows embedders to have control over whether an iframe can start a presentation session.
allow-same-origin: Allows the content to be treated as being from its normal origin. If this keyword is not used, the embedded content is treated as being from a unique origin.
allow-scripts: Allows the embedded browsing context to run scripts (but not create pop-up windows). If this keyword is not used, this operation is not allowed.
allow-top-navigation: Allows the embedded browsing context to navigate (load) content to the top-level browsing context. If this keyword is not used, this operation is not allowed.
allow-top-navigation-by-user-activation: Allows the embedded browsing context to navigate (load) content to the top-level browsing context only when initiated by a user gesture. If this keyword is not used, this operation is not allowed.

Note:

When the embedded document has the same origin as the main page, it is strongly discouraged to use both allow-scripts and allow-same-origin at the same time, as that allows the embedded document to programmatically remove the sandbox attribute. Although it is accepted, this case is no more secure than not using the sandbox attribute.
Sandboxing in general is only of minimal help if the attacker can arrange for the potentially hostile content to be displayed in the user's browser outside a sandboxed iframe. It is recommended that such content should be served from a separate dedicated domain, to limit the potential damage.
The sandbox attribute is not supported in Internet Explorer 9 and earlier versions.

object shape extends Attr
a - This attribute was used to define a region for hyperlinks to create an image map. The values are circle, default, polygon, and rect. The format of the coords attribute depends on the value of shape. For circle, the value is x,y,r where x and y are the pixel coordinates for the center of the circle and r is the radius value in pixels. For rect, the coords attribute should be x,y,w,h. The x,y values define the upper-left-hand corner of the rectangle, while w and h define the width and height respectively. A value of polygon for shape requires x1,y1,x2,y2,... values for coords. Each of the x,y pairs defines a point in the polygon, with successive points being joined by straight lines and the last point joined to the first. The value default for shape requires that the entire enclosed area, typically an image, be used.

object size extends Attr
select - If the control is presented as a scrolled list box, this attribute represents the number of rows in the list that should be visible at one time. Browsers are not required to present a select element as a scrolled list box. The default value is 0.
input - The initial size of the control. This value is in pixels unless the value of the type attribute is text or password, in which case it is an integer number of characters. Starting in HTML5, this attribute applies only when the type attribute is set to text, search, tel, url, email, or password, otherwise it is ignored. In addition, the size must be greater than zero. If you do not specify a size, a default value of 20 is used. HTML5 simply states "the user agent should ensure that at least that many characters are visible", but different characters can have different widths in certain fonts. In some browsers, a certain string with x characters will not be entirely visible even if size is defined to at least x.

img - A list of one or more strings separated by commas indicating a set of source sizes. Each source size consists of:

a media condition. This must be omitted for the last item.
a source size value.

Source size values specify the intended display size of the image. User agents use the current source size to select one of the sources supplied by the srcset attribute, when those sources are described using width ('w') descriptors. The selected source size affects the intrinsic size of the image (the image’s display size if no CSS styling is applied). If the srcset attribute is absent, or contains no values with a width (w) descriptor, then the sizes attribute has no effect.
source - Is a list of source sizes that describes the final rendered width of the image represented by the source. Each source size consists of a comma-separated list of media condition-length pairs. This information is used by the browser to determine, before laying the page out, which image defined in srcset to use.
 The sizes attribute has an effect only when the <source> element is the direct child of a <picture> element.
link - This attribute defines the sizes of the icons for visual media contained in the resource. It must be present only if the rel contains the icon link types value. It may have the following values:

any, meaning that the icon can be scaled to any size as it is in a vectorial format, like image/svg+xml.
a white-space separated list of sizes, each in the format <width in pixels>x<height in pixels> or <width in pixels>X<height in pixels>. Each of these sizes must be contained in the resource.

Usage note: 

Most icon format are only able to store one single icon; therefore most of the time the sizes contains only one entry. MS's ICO format does, as well as Apple's ICNS. ICO being more ubiquitous, you should use it.
Apple's iOS does not support this attribute, hence Apple's iPhone and iPad use special, non-standard link types values to define icon to be used as Web Clip or start-up placeholder: apple-touch-icon and apple-touch-startup-icon.

area - This attribute specifies where to display the linked resource. In HTML4, this is the name of, or a keyword for, a frame. In HTML5, it is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). The following keywords have special meanings:
_self: Load the response into the same HTML4 frame (or HTML5 browsing context) as the current one. This value is the default if the attribute is not specified.
_blank: Load the response into a new unnamed HTML4 window or HTML5 browsing context.
_parent: Load the response into the HTML4 frameset parent of the current frame or HTML5 parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
_top: In HTML4: Load the response into the full, original window, canceling all other frames. In HTML5: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.  Use this attribute only if the href attribute is present.
form - A name or keyword indicating where to display the response that is received after submitting the form. In HTML 4, this is the name/keyword for a frame. In HTML5, it is a name/keyword for a browsing context (for example, tab, window, or inline frame). The following keywords have special meanings:
_self: Load the response into the same HTML 4 frame (or HTML5 browsing context) as the current one. This value is the default if the attribute is not specified.
_blank: Load the response into a new unnamed HTML 4 window or HTML5 browsing context.
_parent: Load the response into the HTML 4 frameset parent of the current frame, or HTML5 parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
_top: HTML 4: Load the response into the full original window, and cancel all other frames. HTML5: Load the response into the top-level browsing context (i.e., the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.
iframename: The response is displayed in a named <iframe>.

HTML5: This value can be overridden by a formtarget attribute on a <button> or <input> element.
link - Defines the frame or window name that has the defined linking relationship or that will show the rendering of any linked resource.

object value extends Attr
meter - The current numeric value. This must be between the minimum and maximum values (min attribute and max attribute) if they are specified. If unspecified or malformed, the value is 0. If specified, but not within the range given by the min attribute and max attribute, the value is equal to the nearest end of the range.
meter - The current numeric value. This must be between the minimum and maximum values (min attribute and max attribute) if they are specified. If unspecified or malformed, the value is 0. If specified, but not within the range given by the min attribute and max attribute, the value is equal to the nearest end of the range.
Usage note: Unless the  value attribute is between  0 and  1 (inclusive), the  min and  max attributes should define the range so that the  value attribute's value is within it.
input - The initial value of the control. This attribute is optional except when the value of the type attribute is radio or checkbox.
 Note that when reloading the page, Gecko and IE will ignore the value specified in the HTML source, if the value was changed before the reload.
li - This integer attribute indicates the current ordinal value of the list item as defined by the <ol> element. The only allowed value for this attribute is a number, even if the list is displayed with Roman numerals or letters. List items that follow this one continue numbering from the value set. The value attribute has no meaning for unordered lists (<ul>) or for menus (<menu>).
Note: This attribute was deprecated in HTML4, but reintroduced in HTML5.
Note: Prior to Gecko 9.0, negative values were incorrectly converted to 0. Starting in Gecko 9.0 all integer values are correctly parsed.
param - Specifies the value of the parameter.
progress - This attribute specifies how much of the task that has been completed. It must be a valid floating point number between 0 and max, or between 0 and 1 if max is omitted. If there is no value attribute, the progress bar is indeterminate; this indicates that an activity is ongoing with no indication of how long it is expected to take.
button - The initial value of the button. It defines the value associated with the button which is submitted with the form data.  This value is passed to the server in params when the form is submitted.
data - This attribute specifies the machine-readable translation of the content of the element.
option - The content of this attribute represents the value to be submitted with the form, should this option be selected. If this attribute is omitted, the value is taken from the text content of the option element.

object width extends Attr
th - This attribute is used to define a recommended cell width.  Additional space can be added with the cellspacing and cellpadding properties and the width of the <col> element can also create extra width. But, if a column's width is too narrow to show a particular cell properly, it will be widened when displayed.

Usage Note: Do not use this attribute in the latest standard: use the CSS  width property instead.
object - The width of the display resource, in CSS pixels.  -- (Absolute values only.  NO percentages)
col, colgroup - This attribute specifies a default width for each column in the current column group. In addition to the standard pixel and percentage values, this attribute might take the special form 0/, which means that the width of each column in the group should be the minimum width necessary to hold the column's contents. Relative widths such as 0.5/ also can be used.
video - The width of the video's display area, in CSS pixels.  -- (Absolute values only.  NO percentages)
td - This attribute is used to define a recommended cell width.  Properties cellspacing and cellpadding may add additional space, and element <col> width may also have some effect. In general, if a column's width is too narrow to show a particular cell properly, it, and thus the cells in it, may be widened when displayed.
Note: Do not use this attribute in the latest standard: instead set the CSS  width property.
iframe - Indicates the width of the frame HTML5 in CSS pixels, or HTML 4.01 in pixels or as a percentage.
canvas - The width of the coordinate space in CSS pixels. Defaults to 300.
pre - Contains the preferred count of characters that a line should have. Though technically still implemented, this attribute has no visual effect; to achieve such an effect, use CSS width instead.
hr - Sets the length of the rule on the page through a pixel or percentage value.
img - The intrinsic width of the image in pixels. In HTML 4, either a percentage or pixels were acceptable values. In HTML5, however, only pixels are acceptable.
table - This attribute defines the width of the table. The width may be defined by pixels or a percentage value. A percentage value will be defined by the width of the container in which the table is placed.
Usage Note: Do not use this attribute, as it has been deprecated. The rules should be defined and styled using  CSS. Use the  width property instead.
embed - The displayed width of the resource, in CSS pixels.  -- (Absolute values only.  NO percentages)
input - If the value of the type attribute is image, this attribute defines the width of the image displayed for the button.

textarea - Indicates how the control wraps text. Possible values are:

hard: The browser automatically inserts line breaks (CR+LF) so that each line has no more than the width of the control; the cols attribute must be specified.
soft: The browser ensures that all line breaks in the value consist of a CR+LF pair, but does not insert any additional line breaks.
off:   Like soft but changes appearance to white-space: pre so line segments exceeding cols are not wrapped and area becomes horizontally scrollable.

If this attribute is not specified, soft is its default value.
pre - Is a hint indicating how the overflow must happen. In modern browser this hint is ignored and no visual effect results in its present; to achieve such an effect, use CSS white-space instead.
