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