<acronym> - HTML: HyperText Markup Language 编辑

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Summary

The HTML Acronym Element (<acronym>) allows authors to clearly indicate a sequence of characters that compose an acronym or abbreviation for a word.

Usage note: This element has been removed in HTML5 and shouldn't be used anymore. Instead web developers should use the <abbr> element.

Attributes

This element only has global attributes, which are common to all elements.

DOM Interface

This element implements the HTMLElement interface.

Example

<p>The <acronym title="World Wide Web">WWW</acronym> is only a component of the Internet.</p>

Default styling

Though the purpose of this tag is purely for the convenience of the author, its default styling varies from one browser to another:

• Some browsers, like Internet Explorer, do not style it differently than a <span> element.
• Opera, Firefox, Chrome, and some others add a dotted underline to the content of the element.
• A few browsers not only add a dotted underline, but also put it in small caps; to avoid this styling, adding something like font-variant: none in the CSS takes care of this case.

It is therefore recommended that web authors either explicitly style this element, or accept some cross-browser variation.
