With this plugin, you will be able to include certain CSS or JS files in only selected posts, pages, or other post types, instead of including them everywhere. You can also edit inline CSS & JS and include CSS & JS files from anywhere on specific posts and pages.
It places meta boxes in the WordPress post editor so it’s easy to select which files you want to include with the post you’re currently editing. This plugin works well for all websites, large and small, and it works well with WordPress multi-site (WordPress MU). Tested up to 3.1 beta 2.
