Find unused css

Question

I'm doing some development for some pages on our internal network. I want to know if there's an open source tool or FF plugin which can identify unused css within a project.

I've looked at using this, but when I try to install the Add-on Installer says "Not compatible with Firefox 3.6"

https://addons.mozilla.org/en-US/firefox/addon/dust-me-selectors/

Please note, this is for an intranet - not a www visible website - so I can't use the online sites which offer such services.

Answer 1

I've been looking for a while, and the best thing I found was this:

http://unused-css.com/

They scan your site and email you the result css.

I am aware you are working on a localsite, however if you find no alternative, you can upload your site somewhere and use this

Alternatively

You could install a previous version of firefox that is compatible with dust-me selectors and run it along side your current installation of firefox.

Answer 2

There is a new program at sourceforge called CSS Scanner, it scans for used and unused css classes and stylesheets in html, aspx, php, javascript and jquery code. It's .net code so you'll need Windows: http://sourceforge.net/projects/cssscanner/
