Template:abbr

The {{abbr}} template is used to write an abbreviation (including an acronym or initialism) with its expanded meaning. It is a wrapper for the HTML element abbr.

Readers on mobile devices typically do not have a mouse to hover with, and so generally cannot see tooltip contents.

Usage

{{abbr|text to display inline in the article|pop-up tip}}

Parameters

Two unnamed (positional) parameters (required) and three named parameters (optional):

• 1 – the term to be explained; displays as text. Wiki markup is allowed but works more consistently when wrapping the template, see below for linking examples.
• 2 – the tooltip/pop-up (no wiki or HTML markup allowed). The popup is created by an HTML title= attribute, so it cannot contain HTML (or markup that resolves to HTML when rendered). This includes simple things like ''italics''.
• class – one or more CSS classes (space-separated if more than one)
• id – an HTML ID must be unique on the entire page.
• style – CSS to apply to the displayed text (no effect on tooltip/popup). Any style values with embedded blanks must be single-quoted

{{abbr|LSD|Louisiana School for the Deaf}} becomes

LSD

When hovering over the text "LSD", something like Louisiana School for the Deaf will appear as a tooltip in desktop browsers. Mobile devices may display a dotted line or other visual indicator of abbreviation, but will not provide the tooltip. No screen readers for the visually impaired will read the expansion by default; some provide an optional setting to read the expansion aloud.
