Scripts n Styles
Scripts n Styles
Description
This plugin allows Admin users the ability to add custom CSS and JavaScript directly into individual Post, Pages or any other registered custom post types. You can also add classes to the body tag and the post container. There is a Global settings page for which you can write Scripts n Styles for the entire blog.
Admin’s can also add classes to the TinyMCE “Formats” dropdown which users can use to style posts and pages directly. As of Scripts n Styles 3+ styles are reflected in the post editor.
Because only well trusted users should ever be allowed to insert JavaScript directly into the pages of your site, this plugin restricts usage to admin type users. Admin’s have access to even more sensitive areas by definition, so that should be relatively safe 😉
Notes about the implementation:
- Admin users, or more specifically, any user with the
manage_optionsandunfiltered_htmlcapabilities (which by default is only the admin type user) can use this plugin’s functionality. Some plugins extend user rolls, and so this plugin would naturally extend include rolls that have the appropriate capability. - CSS Styles are embeded, not linked, at the bottom of the
headelement withstyletags by usingwp-head. If your theme doesn’t have this hook, this plugin (as well as most others) won’t work. - JavaScript is embeded, not linked, at the bottom of the
body(orhead) element withscripttags by usingwp-footer(orwp-head). If your theme doesn’t have this hook, this plugin (as well as most others) won’t work. - There is no input validation. This plugin puts exactly what you type in the meta box directly into the
htmlwith no error checking. You are an Admin, and we trust you to be carefull. Try not to break anything. - Do to the licensing of the libraries used, this plugin is released “GPL 3.0 or later” if you care about those things.
Installation
This plugin does not require any special activation or template tags. Just get it from wordpress.org/extend, install and activate like normal.

Faq
Yes, absolutely. YOU WLL LOSE ALL CUSTOMIZATIONS. Be sure that you do not want these customizations before you uninstall.
Well, because plugins are supposed to, and should be expected to clean up after themselves. If you disable and uninstall the plugin, as a developer, I am supposed to assume that you no longer want me to store all of that now useless data in your database.
Sure, if you are an Admin, just go to the plugin editor and wipe out the uninstall.php and then WordPress will not delete the meta data on uninstall.

Broke my block editor

Broke javascript in the Gutenberg block editor. Editing became painfully slow on my site with this plugin installed. It should be taken off WordPress.org

PERFECT + Does so much more than it says!!
By Natacha (chickwithbob) on January 8, 2019
The plugin lets you add your own code, but has the <script type=”text/javascript”> hardcoded, so it doesn’t help if you need other types of scripts.You can get around this by adding your entire script block using the HTML input area, rather than in the SCRIPTS input area. Fantastic little plugin that has become one of my go-tos in my 'plugin essentials' toolbox. Kudos to the dev for providing their time free of charge for us all to benefit from.
Really Excellent, great!
