| Full | Full | Partial | Partial |
Example
The title
attribute is applied to an abbreviation below:
<p>The page had the phrase <abbr title="Please Turn Over">PTO</abbr>
written on it. If only I knew what PTO meant. So I turned the page
to see if that revealed the answer.</p>
Description
The abbreviation is expanded
within the title attribute, which, while it’s not
technically required for the abbr element, is advisable
at least for the first instance of abbr; 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 abbreviation contained within the element.

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 abbreviation).
In the chart above, the support levels have been decided on this basis:
- full where the browser displays the abbreviation 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
