About CSS StylEditor

A live CSS editor for your browser — edit, see, save. No more page reloads.

What is CSS StylEditor?

CSS StylEditor is a browser extension that lets you edit the CSS files of any website directly in your browser — and see the changes instantly on screen, without saving a file, uploading to a server, or refreshing the page.

The Problem It Solves

Every developer and designer knows the frustration: change one line of CSS, save, switch to the browser, refresh, see the result — then go back to the editor for another small change. This cycle repeats dozens of times a day. CSS StylEditor breaks this cycle entirely.
