CSS-JS-Booster is a PHP-script that tries to automate as many performance
optimizing steps related to CSS and JS embedding as possible.
Depending on the amount of CSS, CSS-images and JS, this can significantly
increase loading speed of your site.
Note: Check by hand the htaccess-part! (see "Installation")
For CSS optimization steps are:
- combine multiple CSS-files resulting in less HTTP-requests
- Optimize and minify CSS with CSSTidy
- Embed any CSS-images smaller 24KB as data-URI or MHTML (for IE <= 7)
- 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 optimization steps are:
- Fetch JS from external servers and cache it locally
- Combine multiple JS-files resulting in HTTP-requests going down
- GZIP-compress the resulting JS
- Have browsers cache the result as long as it remains unchanged
CSS-JS-Booster absolutely requires PHP 5. No PHP 4, sorry...
Version-wise it is tested up until PHP 5.3.
- Copy the whole
booster-folder into wp-content/plugins/
- If not already there: create a subfolder named
booster_cache inside wp-content/ and CHMOD it to 0777 (give it write-permissions)
- Go into the admin-panel to the plugins and activate
CSS-JS-Booster
- Check if the contents of the file
wp-content/plugins/booster/htaccess/.htaccess were put into/appended to the .htaccess-file in the root of your Wordpress-site. If not append them by hand.
Compatibility with other plugins
CSS-JS-Booster may in rare cases break some other plugins.
I noticed for example that plugins trying to calculate file-paths based on the src-attribute of the script-tag break.
So you need to check yourself.
If your site has many visitors, we suggest that you combine CSS-JS-Booster with WP-Super-Cache.
