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 {{HTMLElement("abbr")}} element.
Attributes
This element has no other attributes than the global attributes, common to all elements.
DOM Interface
This element implements the HTMLElement
interface.
Implementation note: Up to Gecko 1.9.2 inclusive, Firefox implements the
HTMLSpanElement
interface for this element.Example
<p>The <acronym title="World Wide Web">WWW</acronym> is only one 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 IE, do not style it differently than a {{HTMLElement("span")}} element.
- Opera, Firefox, 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 take cares of this case.
It is therefore strongly recommended that web authors do not rely on the default styling.
