alt Alternative Text
Word or phrase that serves as a textual alternative for the element.
Usage/Remarks
Usage
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, to differentiate, for example, as part of an <abbrev>, that the WHO should not be pronounced as the “who”, but rather pronounced as the
“W.H.O.” or as the “World Health Organization”.
Accessibility Best Practice
Please reserve this attribute for accessibility uses such as
pronouncing screen readers. For example, it could be used to provide a textual interpretation
of an
emoticon (for example, “wink, frown” for the emoticon “ ;-(”).
