In HTML, the abbr element is used to define an abbreviation or acronym. The abbr element is written as <abbr> and is usually used in conjunction with the title attribute, which specifies the full version of the abbreviation or acronym.

For example, the following code defines the abbreviation “HTML” as the Hypertext Markup Language:

<abbr title=”Hypertext Markup Language”>HTML</abbr>

When the abbreviation is displayed on the page, the title attribute will not be visible to the user. However, when the user hovers over the abbreviation with their cursor, a tool tip will appear displaying the full version of the abbreviation.

The abbr element is used to provide additional context and meaning to abbreviations and acronyms, which can help improve the accessibility of a webpage for users with disabilities or for users who are not familiar with certain terminology.
