Template:Abbr/doc

abbr is used to define an abbreviation or acronym by creating a tooltip that is displayed on mouse-over. The template uses the HTML &lt;abbr> element and is supported by most browsers.

Usage
abbr takes two unnamed parameters, in order:
 * short form: shows as text
 * long form: shows as the tooltip

Named parameters:
 * IPA or i: Applies IPA to fix strings in the International Phonetic Alphabet rendered in Internet Explorer on Windows XP.
 * unicode or u: applies unicode to fix strings in Unicode rendered in Internet Explorer on Windows XP.
 * class: adds an HTML class
 * id: adds an HTML id

Examples
When hovering over the text "MSLP" then something like Mean Sea Level Pressure will appear as a tooltip in most browsers. Popular screen readers, used by visually impaired readers, display the long form in a different way.

Accessibility concerns
This template is intended for use with abbreviations; it is not intended to be a tool for generating tooltips.
