Element HTML abbreviations () is an acronym or abbreviation; optional attribute title can provide an extension or description of an abbreviation. If present, the title must contain this full description and nothing more.
Article How to mark abbreviations and make them clear is a training manual for use and related elements.
Attributes
This element only supports global attributes. The title attribute has a specific semantic meaning when used with an element ; He must contain a complete human-readable description or abbreviation extension. This text is often displayed by browsers as a tooltip when the mouse cursor hovers over an element.
Each element you use is independent of everyone else; providing a title for one does not automatically attach the same extension text to others with the same content text.
Notes on use
Typical Use Cases
Of course, it is not required that all abbreviations be marked with . However, there are a few cases where this is useful:
Grammar Considerations
In languages with grammatical number (that is, languages where the number of elements affects the grammar of the sentence), use the same grammatical number in the title attribute as inside your element . This is especially important in languages with more than two numbers, such as Arabic, but is also relevant in English.
Default style
The purpose of this element is purely for the convenience of the author, and all browsers render it inline (display : inline) by default, although its default style varies from one browser to another:
- Some browsers, such as Internet Explorer, do not build it differently than the element .
- Opera, Firefox and some others add a dotted line to the element's content.
- A few browsers not only add dotted underlining, but also put it in small caps; to avoid this style, adding something like font-variant : none in the CSS will not take care of this case.
Examples
Marking an abbreviation semantically
To tag an abbreviation without providing an extension or description, simply use without any attributes, as shown in this example.
