Offered as a service from the WebAIM website, Maine CITE provides the following “tip” on how to make your website more accessible to all people.
Acronyms and Abbreviations
Acronyms, abbreviations, and unfamiliar terms should be expanded and explained at their first instance in a web page. This ensures that all users are presented with their meaning. Although HTML provides <abbr> for authors to define acronyms and abbreviations, the expanded meanings are still inaccessible to many users (keyboard or touchscreen users, some screen reader users, etc.), and we discourage its use.
