alt Alternative Text

Word or phrase that serves as a textual alternative for the element.


Provides, for the elements on which it is allowed, the same type of service for pronouncing screen readers and other accessibility software as the element <alt-text> provides for graphics and other objects. This attribute contains a word or phrase used to provide a very short textual alternative to a component such as an abbreviation or cross-reference. The content of the attribute can be used for special accessibility presentation, for example, to differentiate (as content of an <abbrev> element) that the WHO should not be pronounced as the “who”, but rather be pronounced as the “W.H.O.” or as the “World Health Organization”.
