This plugin is useful if you have want to enable your users to insert custom CSS or add custom headers or some JavaScript into the site without having to edit any theme files. Unlike similar header/footer plugins, this plugin by design does not allow to insert PHP code and does not contain any evil eval() calls.
The plugin is safe to use in WordPress Network installations, where site admins are not supposed to have PHP execution access but any HTML/CSS/JS code is safe to accept.

Thank you for this simple and effective plugin.
I’ve tried using it with shortcodes, but it doesn’t seem to work.
I’d like to place a static block into it and then design the block with a drag and drop builder. That would expand the usability of the plugin so much!
It works.
Crude and simple, but works well..
Works as advertised, no hassle! Great tool!
Simple and does the job. Thank you
