My website has 6 to 8 plugins installed and I am interested in knowing if there is a way to combine all css files from these plugins into one or two files
Thanks
This may help you Combine and Minify Multiple CSS / JS Files or this Are there any tools for merging CSS? By the way I found this : http://wordpress.org/plugins/wp-minify/
How Does it Work?
WP Minify grabs JS/CSS files in your generated WordPress page and passes that list to the Minify engine. The Minify engine then returns a consolidated, minified, and compressed script or style for WP Minify to reference in the WordPress header.
