What is the Abbr Element and Title Attribute?

Understanding the Abbr Element

The <abbr> element represents an abbreviation or acronym in HTML. It's a semantic element that tells browsers, search engines, and assistive technologies that the enclosed text is a shortened form of a longer phrase or term.

This element provides meaning to abbreviations like "HTML," "CSS," "API," or "FAQ," making your content more accessible and understandable for all users.

Understanding the Title Attribute

The title attribute works with the <abbr> element to provide the full expansion or explanation of the abbreviation. When users hover their mouse over the abbreviated text, a tooltip appears showing the complete meaning.

Together, these features create a powerful combination that enhances user experience while maintaining clean, readable content.
