What is CSS-JS-Booster?

CSS-JS-Booster is a PHP-script that tries to automate as many performance
optimizing steps related to CSS and JS embedding as possible.

For CSS these steps are:

• combine multiple CSS-files resulting in HTTP-requests going down
• minify CSS
• Embed any CSS-images smaller 24KB as data-URI or MHTML (for IE <= 7)
• Split the output back into 2 even files that can load in parallel (not for WP)
• GZIP-compress the resulting CSS
• Have browsers cache the result as long as it remains unchanged
• If IE6: Issue a JS-command to fix background image caching behaviour

For JS these steps are:

• combine multiple JS-files resulting in HTTP-requests going down
• Minify the JS through the Google Closure Compiler Webservice, or JSMin as fallback (not for WP)
• GZIP-compress the resulting JS
• Have browsers cache the result as long as it remains unchanged

+ GZIP-compresses the page calling those files.

Depending on the amount of CSS, CSS-images and JS, this can significantly
increase loading speed of your site.
