I'm trying to reduce the size of my CSS file. It is from a template which is very CSS & JS heavy. Even with CSSMin the CSS file size is 250kb.
Whilst I use alot of the CSS - I know I dont use it all. So I'm trying to work out which styles can be removed. I'm aware of Dust-Me selector - but that only takes a static look at the website. With HTML5 and CSS3 - websites are now very dynamic, and most of my CSS occurs from dynamic events, or 'responsive' events i.e. Bootstrap.
Question: Is there a tool which 'records' all my CSS use on a website for a perioid of time, so I can go and click/hover/move over each element and interact with my site. Then at the end let me know which styles were & were not used?
250kb is really such a big figure for just CSS files.
The templates generally have all the CSS required for all the pages in a single file.
I would suggest:
Do not cut your CSS code, they might be needed some point of time.
Instead i would suggest, break your CSS file into number of small files for different page stylings,
such as a different CSS for login page, different CSS file for home page, etc.
Read your own CSS and HTML code vigorously to find out which significant part of CSS code is used in which HTML section.
Update:
You may try Removed Unused CSS - CSS optimizer.
I personally did not use it just hope it works for you.
