GlobalAttrs

This class of attributes, called custom data attributes, allows proprietary information to be exchanged between the HTML and its DOM representation that may be used by scripts. All such custom data are available via the HTMLElement interface of the element the attribute is set on. The HTMLElement.dataset property gives access to them.

The * may be replaced by any name following the production rule of xml names with the following restrictions:

the name must not start with xml, whatever case is used for these letters; the name must not contain any semicolon (U+003A); the name must not contain capital A to Z letters.

Note that the HTMLElement.dataset attribute is a StringMap and the name of the custom data attribute data-test-value will be accessible via HTMLElement.dataset.testValue as any dash (U+002D) is replaced by the capitalization of the next letter (camelcase).

MDN

Allows you to modify a ConcreteHtmlTag by adding a Seq containing other nest-able objects to its list of children.

Constructs an Attr attribute object from a string; can be used inline:

 div(
   attr("hello-world-special-attr") := "foo
 )

Or assigned to a name and used later

 val hello = attr("hello-world-special-attr")
 div(
   hello := "foo
 )

Constructs a CSS Style from a string, can be used inline

 div(
   css("-moz-special-style") := "foo"
 )

Or assigned to a name and used later

 val mozSpecial := css("-moz-special-style")
 div(
   mozSpecial := "foo"
 )

This attribute is a space-separated list of the classes of the element. Classes allows CSS and Javascript to select and access specific elements via the class selectors or functions like the DOM method document.getElementsByClassName. You can use cls as an alias for this attribute so you don't have to backtick-escape this attribute.

MDN

Specifies a shortcut key to activate/focus an element

Shorthand for the class attribute

Specifies the text direction for the content in an element. The valid values are:

• ltr Default. Left-to-right text direction

• rtl Right-to-left text direction

• auto Let the browser figure out the text direction, based on the content, (only recommended if the text direction is unknown)

A Boolean attribute that specifies whether an element is draggable or not

Specifies whether the dragged data is copied, moved, or linked, when dropped

Specifies that an element is not yet, or is no longer, relevant and consequently hidden from view of the user.

This attribute defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).

MDN

This attribute participates in defining the language of the element, the language that non-editable elements are written in or the language that editable elements should be written in. The tag contains one single entry value in the format defines in the Tags for Identifying Languages (BCP47) IETF document. If the tag content is the empty string the language is set to unknown; if the tag content is not valid, regarding to BCP47, it is set to invalid.

MDN

This enumerated attribute defines whether the element may be checked for spelling errors.

MDN

This attribute contains CSS styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the style element have mainly the purpose of allowing for quick styling, for example for testing purposes.

MDN

This integer attribute indicates if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position. It can takes several values:

• a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation;
• 0 means that the element should be focusable and reachable via sequential keyboard navigation, but its relative order is defined by the platform convention;
• a positive value which means should be focusable and reachable via sequential keyboard navigation; its relative order is defined by the value of the attribute: the sequential follow the increasing number of the tabindex. If several elements share the same tabindex, their relative order follows their relative position in the document).

An element with a 0 value, an invalid value, or no tabindex value should be placed after elements with a positive tabindex in the sequential keyboard navigation order.

This attribute contains a text representing advisory information related to the element it belongs too. Such information can typically, but not necessarily, be presented to the user as a tooltip.

MDN

Specifies whether the content of an element should be translated or not
