The attribute describes the role(s) the current element plays in the context of the document.
The attribute describes the role(s) the current element plays in the context of the document. This can be used, for example, by applications and assistive technologies to determine the purpose of an element. This could allow a user to make informed decisions on which actions may be taken on an element and activate the selected action in a device independent way. It could also be used as a mechanism for annotating portions of a document in a domain specific way (e.g., a legal term taxonomy). Although the role attribute may be used to add semantics to an element, authors should use elements with inherent semantics, such as p, rather than layering semantics on semantically neutral elements, such as div role="paragraph".

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.
A name or keyword indicating where to display the response that is received after submitting the 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 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 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, canceling all other frames. 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. - iframename: The response is displayed in a named iframe.
