HTML Tags

HTML <acronym> Tag

Written by Updated

The <acronym> tag in HTML was used to define an acronym - a word formed from the initial letters of other words, such as NASA or HTML.
When a user hovered over the acronym, the browser could display its full meaning using the title attribute.
This tag is deprecated in HTML5 and replaced by the <abbr> tag.

  • Use the <abbr> tag instead, which provides the same functionality and is supported by modern browsers.
  • The title attribute is what displays the tooltip on hover.

Conclusion

The <acronym> tag was once used to define acronyms in HTML documents, but it is now obsolete.
For modern, accessible, and valid HTML, use the <abbr> tag instead.
