<a href="http://pjdietz.com/wordpress-plugins/custom-css-js/" rel="nofollow ugc">Custom CSS and JS</a> allows you to add stylesheets and JavaScripts to any individual post by adding custom fields. Both CSS and scripts can be either internal or external. Since this is a plugin, the custom CSS and JavaScript are available to any theme used to display the post, as long as the themes call “wp_head”.
<h3>Using the Plugin</h3>
To use the plugin, add any combination of the following custom fields to your post.
custom_css 
Add an external stylesheet by adding a custom field with the name custom_css. The value of the field should be the path to your css file.
cusrom_css_code 
Add an internal stylesheet by adding a custom field with the name custom_css_code. Include your CSS code as the value. (Do not include the style tags.)
custom_js 
Add an external JavaScript by adding a custom field with the name custom_js. The value of the field should be the path to your script.
custom_js_code 
Add an internal JavaScript by adding a custom field with the name custom_js_code. Include your JavaScript code as the value. (Do not include the script tags.)
<h3>Custom Fields Order</h3>
<ol>
<li>The external styles and scripts are included before the internal ones.</li>
<li>If you include multiple entries for a given field, the entries will be included in order.</li>
</ol>
<h3>Okay, but what if I don’t like those tags?</h3>
Just edit custom-css-js.php and change the constants defined near the top of the file.
<h3>Note</h3>
This plugin only works with individual posts and pages. It does not work for list pages (e.g., the index page, search results).
