I’ve been working on a tool that shows where the css rules on a page interact with the markup.
[http://css.benjaminbenben.com](http://css.benjaminbenben.com/ )
It’s still quite rough (it won’t work in firefox because of the way that I’m sending the screenshots).
I’ve started a [blog post](http://benjaminbenben.com/2013/05/09/wtcss/ “Visualising CSS selector matches”) about why I built it initially – to see if selectors became more specific as a css file grows in size.
I was wondering:
* is this a useful thing to know?
* are there any better things it could be used for?
General / other feedback would be awesome too.
