About Insert JavaScript and CSS
From the official readme · v0.2Description
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.
