HTML acronym tagWhen writing in HTML, the <acronym> tag is an inline element used to create an acronym. It is useful when you want to shorten a phrase, but still want to give additional information to visitors, search engines, and browsers. The following sections contain information about this tag, including an example of it in use, as well as related attributes and browser compatibility.

Note: This tag is deprecated. Going forward, the <abbr> tag should be used instead.

Example code

The <acronym title="Central Processing Unit">CPU</acronym> ran hot.

Example result

The CPU ran hot.

Tip: Notice that the word "CPU" displays "Central Processing Unit" when you hover your mouse cursor over it.


Within an HTML tag, an attribute dictates certain aspects of an HTML element. Attributes are made up of a name and value pair. While the <acronym> tag does not have any unique attributes, it does utilize all of the standard attributes.
