I have used a standard-styles.css file for over a year and it is quite extensive. I have been embedding it into my [template]-custom.css file but was wondering if I would not incur a page load hit if I simply upload my standard-styles.css file into the 'css' folder, use "@import url('standard-styles.css');" in the [template]-custom.css and then use an optimization plug-in like RokBooster, Jbetolo, JCH Optimize, etc. to compress the CSS?
Just convenience. If I make a change to my standard-styles.css, I have to make that change in every clients website custom css file. If I used @import, I would just upload the standard-styles.css to their 'css' folder. I don't think I would use a 'remote' url such as @import "http://blahblahblah/download/standard-styles.css" but, man, that would be convenient.
