Don’t just test classes #1

It would be great if the bookmarklet could test elements with IDs as well. Ultimately it would just test every CSS selector in use, including those that don’t use IDs or classnames, but I can see how that would complicate things.

Yeah, I had that thought as well. ID's wouldn't be hard, but all selectors would be pain. I had the thought that I could use AJAX to grab text versions of all the page CSS, parse the selectors, but then I wasn't sure how I could disable a specific selector.

I just released the ability to test ID's.

To test all selectors, I think I'll have to parse the CSS completely, find the elements that match the selector, and try to set each property specified by the rule, to the default--I don't think you can simply remove a property.
