| No | HTML 4 |
Example
The title
attribute is applied to an acronym below:
<p>He marvelled at how fluid the <acronym title="Graphical User
Interface">GUI</acronym> was. It truly was a gooey GUI.</p>
Description
The abbreviation is expanded
within the title attribute, which, while it’s not
technically required for the acronym element, is
advisable at least for the first instance of acronym;
otherwise, you’d be indicating an abbreviation but not providing any
further information about what it’s an abbreviation of.
Value
The content of this attribute is the
fully expanded version of the content contained between the opening
<acronym> and closing </acronym>
tags.

Browser support is
mixed for this attribute in this instance (note that
title is used for other elements—the compatibility
notes here relate only to its ability to draw attention to the
presence of an acronym).
In the chart above, the support levels have been decided on this basis:
- full where the browser displays the acronym with an underline and provides tooltip on mouseover
- partial where the browser provides a tooltip on hover, but doesn’t display an underline (though it can be styled with CSS and accessed using JavaScript and the DOM)
- none where no visual rendering is provided, and the attribute isn’t recognized in the DOM
