HTML attribute
An HTML attribute is a modifier of an HTML element.
Description
HTML attributes 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.
