Reply To: Combine CSS files
I tried a few plugins, but yes, the only one that actually did work was W3.
But it is not automatic. You will have to do it manually, by adding one css file at a time to the settings, to see if that breaks the site or no. Then if the result is ok, add one more check again and so on.
You might also have to change the sequence of the files added to the W3 settings, because sometime there are dependencies that break the site.
After combining the files, I dropped the loading time of the website from 26-27 seconds, down to 4-5 seconds!
