The address element

An element used for contact information for people or organization.

From the address spec

The address element represents the contact information for its nearest article or body element ancestor. If that is the body element, then the contact information applies to the document as a whole.

I used the address element in the footer on this website with the following markup:

<address>
 You can find me on <a href="https://bsky.app/profile/lmfaole.party">Bluesky</a>.
