About Stylus

Stylus is a browser extension that restyles websites by injecting its own CSS into targeted pages, overriding a site's existing design. It is a fork of Stylish based on version 1.5.2, created to remove analytics and data collection from the earlier codebase and to return to a simpler interface. Users who know CSS can write their own styles; others can install styles by other authors from userstyles.org and search that site for the current page from inside the extension. It is available for Chrome, Firefox and Opera. Installed styles can update automatically on an interval the user sets, and a backup feature compatible with Stylish allows a style database to be exported from Stylish and imported into Stylus.

Stylus FAQ

Which browsers is Stylus available for?
The extension is available for Chrome, Firefox and Opera.
Do I need to know CSS to use Stylus?
Not necessarily. If you know CSS you can write your own styles; otherwise you can install styles created by other authors from userstyles.org.
Can I move my existing styles from Stylish to Stylus?
Yes. Stylus includes a backup feature compatible with Stylish: export your database from Stylish and import it into Stylus. For the Stylish for Firefox add-on, the homepage notes a deprecated workaround using an experimental extension to generate a Stylus-compatible JSON file.
