Can you optimize CSS?
 

I've been modifying and modifying the css and html for a site. I think there might be a lot of extra css that I'm not using anymore. I'd like to remove it. Is there a tool to automate this?

This tool can help tweak up the css:-

dont know of any tool other than to delete the lines not in use

Going to try this, thanks for sharing!

Thank you. Page Speed said I had about 20% of unused css.

don't pay much attention to that, most of the times extreme CSS optimization implies that you'll go crazy every time you need to edit the file again.

Anyway, if you really, really, REALLY need it, do the following:

- be sure to reduce all the elements sharing the same definitions resetting them on start. ie, if your images are going to have no borders, just img{border:0}, html{margin:0;}, h1, h2, h3{color:#333;}, and so on.

- use any of tidy service out there. Personally, I like http://www.cleancss.com/ since it has some control to balance readability and size
