Make it Splendid with Styles.
All from within WordPress.

No more loading scripts on every post that only a few use.
Postscript lets you easily add libraries or single-post script and style files post-by-post.

mprove site performance:
- Clean up the post content box.
- Improve site performance.
- Control dependencies (when registering scripts).
- Load styles in the head and scripts in the footer.
- Eliminate loading multiple copies of the same library (jQuery, I’m looking at you).
What it does
Enqueue registered styles and scripts (by handle)
Use the Postscript meta box (Edit Post screen) to enqueue registered of styles and scripts (listed in checkboxes by handle.).

Registration scripts/styles in WordPress
Your scripts and styles
You can register your own CSS/JS file handles with the wp_register_script() and the wp_register_style() functions.
Only handles you register via the wp_enqueue_scripts hook list on Postscript’s Settings screen. This list also has handles registered by your active theme and plugins and the defaults registered by WordPress itself.
Default scripts and styles
WordPress registers numerous styles and scripts via its core functions: wp_default_scripts() and wp_default_styles(). Each file gets its own unique handle: see the list of defaults.
An example: Thickbox
WordPress ships with a modified ThickBox jQuery library, used to make modal lightbox windows. The add_thickbox() function enables this feature, but it also loads Thickbox’s CSS and JS files on every Post, whether or not the post needs it.
This plugin improves site performance by only enqueuing scripts only when speficially requested for an individual post, by checking the Thickbox Script and Styles handles in the Postscript box. See the screenshots.
