Usage notes

Typical use cases

It's certainly not required that all abbreviations be marked up using <abbr>. There are, though, a few cases where it's helpful to do so:

  • When an abbreviation is used and you want to provide an expansion or definition outside the flow of the document's content, use <abbr> with an appropriate title.
  • To define an abbreviation which may be unfamiliar to the reader, present the term using <abbr> and either a title attribute or inline text providing the definition.
  • When an abbreviation's presence in the text needs to be semantically noted, the <abbr> element is useful. This can be used, in turn, for styling or scripting purposes.
  • You can use <abbr> in concert with <dfn> to establish definitions for terms which are abbreviations or acronyms. See the example Defining an abbreviation below.

Grammar considerations

In languages with grammatical number (that is, languages where the number of items affects the grammar of a sentence), use the same grammatical number in your title attribute as inside your <abbr> element. This is especially important in languages with more than two numbers, such as Arabic, but is also relevant in English.

Default styling

The purpose of this element is purely for the convenience of the author and all browsers display it inline (display: inline) by default, though its default styling varies from one browser to another:

  • Some browsers, like Internet Explorer, do not style it differently than a <span> element.
  • Opera, Firefox, and some others add a dotted underline to the content of the element.
  • A few browsers not only add a dotted underline, but also put it in small caps; to avoid this styling, adding something like font-variant: none in the CSS takes care of this case.

Examples

Marking up an abbreviation semantically

To mark up an abbreviation without providing an expansion or description, simply use <abbr> without any attributes, as seen in this example.

HTML

<p>Using <abbr>HTML</abbr> is fun and easy!</p>

Result

Styling abbreviations

You can use CSS to set a custom style to be used for abbreviations, as seen in this simple example.

HTML

<p>Using <abbr>CSS</abbr>, you can style your abbreviations!</p>

CSS

abbr {
  font-variant: all-small-caps;
}

Result

Providing an expansion

Adding a title attribute lets you provide an expansion or definition for the abbreviation or acronym.

HTML

<p>Ashok's joke made me <abbr title="Laugh Out Loud">LOL</abbr> big
time.</p>

Result

Defining an abbreviation

You can use <abbr> in tandem with <dfn> to more formally define an abbreviation, as shown here.

HTML

<p><dfn id="html"><abbr title="HyperText Markup Language">HTML</abbr>
</dfn> is a markup language used to create the semantics and structure
of a web page.</p>

<p>A <dfn id="spec">Specification</dfn>
(<abbr title="Specification">spec</abbr>) is a document that outlines
in detail how a technology or API is intended to function and how it is
accessed.</p>

Result

See more in-depth examples in the How to mark abbreviations and make them understandable article.

Accessibility concerns

Spelling out the acronym or abbreviation in full the first time it is used on a page is beneficial for helping people understand it, especially if the content is technical or industry jargon.

Example

<p>JavaScript Object Notation (<abbr>JSON</abbr>) is a lightweight data-interchange format.</p>

This is especially helpful for people who are unfamiliar with the terminology or concepts discussed in the content, people who are new to the language, and people with cognitive concerns.
