<acronym>

The <acronym> element was used to highlight acronyms.

Note: This is deprecated. The <abbr> tag is used instead. When the tag is used, the acronym will be signified with a dotted underline for the word or phrase.

Syntax

<p>
  A great place to learn to code is <acronym title="Codecademy">CC</acronym>
</p>

The title attribute adds meaning of the acronym. It is not required but, when omitted, nothing will happen when it is hovered over.

Example

<p>
  Tomorrow I'll be heading to the Kennedy Space Center to learn about the
  National Aeronautics and Space Administration (NASA). Touring through the
  rockets used in
  <acronym title="National Aeronautics and Space Administration">NASA</acronym>
  will be such fun!
