Element Attribute Test

On this page, I am testing every possible HTML attribute you can place on an HTML element to see what Wikidot will accept. I suspect not many but there's only one way to find out! Most of these are pulled from the w3 wiki.

Findings

Wikidot only accepts id, class, and style.
Additionally, it always adds the u- string to the beginning of an id.

So, findings are disappointing.
