Abbreviations and acronyms

abbr and acronym are used for abbreviations and acronyms respectively.

An abbreviation is a shortened form of a phrase. Very general. An acronym however is an abbreviation made up of the initial letters (or parts of words) of the phrase it is representing. So CSS is a valid acronym, whereas HTML and XHTML are not (if 'Hypertext markup language' was an acronym, it would be 'HML'. Similarly, XHTML would be EHML).

For optimum accessibility, the phrase that the acronym or abbreviation is representing should be used in the title attribute.

For example:
<p>This web site is about <abbr title="HyperText Markup Language">HTML</abbr> and <acronym title="Cascading Style Sheets">CSS</acronym>.</p>

The label tag sorts this out, with a for attribute that associates it to a form element:
