HTML acronym Tag

The <acronym> tag was proposed in older versions of HTML but was never officially included in the HTML specifications. The recommended way to mark up abbreviations and acronyms in HTML is by using the <abbr> tag as described in my previous response.

If you encounter any resources or examples mentioning the <acronym> tag, it is likely outdated or non-standard usage. It is always best to follow the latest HTML standards, which currently do not include the <acronym> tag.
