Custom CSS

Inject custom CSS styles into any website

Custom CSS lets you inject your own styles into any website directly from the browser. Open the extension popup, type your CSS rules, and save them per site. Styles are applied automatically every time you visit a saved page, so you never have to rely on external tools or bookmarklets. The extension stores all your styles locally in your browser — nothing is sent to any server. The built-in list of saved sites makes it easy to manage, edit, or remove rules at any time. Custom CSS gives you full control with a clean and minimal interface.
