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.

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..
