Favorite HTML Attribute?

This question came from the old anonymous AMA I used to have. In relaunching the AMA concept on GitHub Discussions, I wanted to bring over as many of these as I could

ismap: Link

This Boolean attribute indicates that the image is part of a server-side map. If so, the coordinates where the user clicked on the image are sent to the server.

There's almost never a time you need this, but back in the days of early Internet forums, you could often use an img tag but not an a tag. This was the way to make a really neat image signature that could link off to multiple places based on a coordinate system. Server side image maps were definitely up there in terms of weird and cool; for me that makes a favorite.

Update 2021 I still love ismap, but HTML5 also gave us type for input elements which might actually be 100x more useful.
