View source for HTML attribute

An [[HTML]] attribute is a modifier of an HTML [[element]]. 

They are usually added to a HTML start tag, which along with content and end tag comprises most HTML elements. 

Particular attributes are only supported by particular element types; if they are added to elements that do not support them they will not function.

Some attributes are required attributes, needed by particular element types for them to function correctly; while in other cases they are optional attributes, only needed when something other than the default formatting is required. 

Standard attributes are supported by a large number of element types; they include [[event]] attributes, which [[trigger]] elements to specify [[scripts]] to be run under specific circumstances.

Although some attributes are used in more than one type of HTML element, they do not necessarily have the same function in different types of elements. For example the attribute name is used by several element types, but has slightly different functions in each.
