Custom Stylesheet & Script

Inserts a custom stylesheet and script into every web page.

Custom Stylesheet & Script: Modify Web Pages with Your Own Code

Custom Stylesheet & Script is a unique Chrome extension designed for profound personalization of browser experience. This tool allows users to write and apply their own JavaScript and CSS codes to each web page they open, providing the ultimate control over the website's looks and functionalities. The extension does not carry out any modifications on its own as it comes empty - users are expected to provide their scripts and stylesheets. This dynamic utility further supports automatic save as you edit and only applies changes to web pages when refreshed.

Extension summary

This is simple extension that inserts custom JavaScript and CSS code into each web page, allowing you to modify the way it behaves and looks.

The default installation does nothing. You'll have to provide the script and stylesheet yourself. An example can be found here: https://github.com/Rufflewind/chrome_script/tree/master/example

To edit the script and stylesheet, go to chrome://extensions and click "Options" under "Custom Stylesheet & Script".

The text areas in the "Options" tab will automatically save as you edit. Existing pages are not affected until refreshed.

Note: jQuery NOT included anymore as of 2.0.0.

Doesn't seem to work at all in Opera GX, July 2023

It just works as advertised. No useless fireworks. You add CSS, JS code and it injects it into web page. I use it to nuke annoying top banners in Google docs published to web. Also to override eye killer dark theme on YouTube with my own that does not destroy my eyesight and does not create head splitting headaches..
