Optimization- Is there any way to find and remove unused CSS and Javascript common to all html pages? [closed]

Answer 1

You can use GTmetrix to clean up CSS code at http://gtmetrix.com/remove-unused-css.html. Give the URL and press GO!

http://www.peterbe.com/plog/mincss is a tool that when given a URL (or multiple URLs) downloads that page and all its CSS and compares each and every selector in the CSS and finds out which ones aren't used. The outcome is a copy of the original CSS but with the selectors not found in the document(s) removed.

you can also use the google chrome audit tool refer to this website http://blackbe.lt/removing-unused-css-selectors-with-google-chrome-tool/

or you can use the google chrome extensions
