Easily add custom JavaScript or CSS to a single post or page.
When activated, a new icon is added to the post edit page near the icon you use 
to add media to a post. Clicking the new icon brings up a screen where you can 
insert JavaScript and CSS that will be included with the current post.
Anything entered into the text field on the JavaScript tab will be inserted into 
the <head> section of your web page. Same is true of the CSS tab. This allows 
you to insert arbitrary JavaScript and CSS into any post or page you would 
like without having to resort to loading it on all pages.

Insert JavaScript and CSS

Adds fields to the post and page edit pages that allow you to insert custom JavaScript or CSS for that post or page.

<h3>User Access Control</h3>
In the Custom CSS and JavaScript WordPress plugin, access to plugin features is determined by user capabilities. Users with the <code>edit_theme_options</code> capability will enjoy full access to all the plugin’s features.
By default, the “Administrator” and “Editor” roles come equipped with the <code>edit_theme_options</code> capability. However, site administrators have the flexibility to customize these capabilities and assign them to other roles or individual users through plugins or custom code.
Furthermore, to provide users with enhanced control, we’ve introduced a custom capability known as <code>wpz_custom_css_js</code>. Users possessing both the <code>wpz_custom_css_js</code> and <code>edit_posts</code> capabilities can be granted access to the plugin’s features.
