Introduction to <acronym>

In HTML <acronym>is an abbreviation of a word or phrase. This is actually obsolete, the proper way to define this tag would have been using the acronym tags which no longer exists because it has changed for <acronym>. The abbr tag is a way to specify abbreviations or acronyms, with the full form appearing as a message when hovered over.

Warning: Do not use this element. Use the <acronym>element instead.

This feature has been deprecated. Although this may not be a risk anymore, it is still listed in the relevant web standards as abandoned or deprecated and will probably only maintain for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your usage. Keep in mind, this may break at any moment.
