I 've searched on google some online unused css removers that you have to pay. I also checked here on stackoverflow for programs that might do that. I only found an easy way via google chrome.
The thing is that this one does it for one page (current) only. I have a website with three pages here : PAGE 1 , PAGE 2 , PAGE 3. I want to find the unused css parts of all the three pages at the same time. Is there a tool or a website that does it for free ?
Try "Dust-Me Selectors" add-on for Firefox. It has the ability to crawl, even thru a given sitemap.
I also wish Google Audit had that feature.
