Template:Abbr/doc

abbr is an abbreviation template. It works similarly to the HTML &lt;abbr> or &lt;acronym> tags.

Usage
undefined takes two unnamed parameters, in order:
 * 1) The short form, which shows as text on the page
 * 2) The long form, which the short form is an abbreviation for

Many web browsers (such as Firefox, Google Chrome, Internet Explorer, Opera, Safari) show the long form as a tooltip when a user hovers over the text. However, this behavior is not guaranteed and should not be relied on.

There is an option for a third parameter: adding "unicode" (or "u") applies unicode to the text of parameter 1. This may resolve rendering issues with browsers which do not apply the proper font to the text. Other fonts/languages may be added to the code as needed. If the third parameter is not defined, it will be ignored.

The template also has two named parameters:


 * class
 * id

which create the corresponding HTML attributes on the  element.

The former can be used in microformats.

With two parameters
MSLP

appears as MSLP. When hovering over the text, something like Mean Sea Level Pressure appears as a tooltip in many (but not all) browsers. Popular screen readers, used by visually impaired readers, display the long form in a different way.

With three parameters
pȅći • пе̏ћи

appears as pȅći • пе̏ћи. Compare pȅći • пе̏ћи without the Unicode formatting.

With named parameters
UK appears as UK.

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