Stylus is a fork of Stylish for Chrome, also compatible with Firefox as a WebExtension
- In addition to the userstyles.org site, styles with customizable parameters can also be installed from .user.css or .user.styl URLs (see Usercss format wiki).
- Site styles can be discovered and previewed in the popup using inline search with screenshot thumbnails.
- A backup feature which is compatible with other userstyles managers.
- Configurable automatic update function for installed styles.
- Customizable UI, optional layouts, and tweaks.
- Two different optional code validators with user-configurable rules: CSSLint and Stylelint.
- Both validators use Web Worker API to run in a separate background thread inside the editor tab without blocking your interaction with the code.
- CSSLint is heavily modified compared to the effectively frozen original one and supports various CSS3 features as well as CSS4 Color and CSS Grid syntax.
The source is hosted on GitHub and pull requests are welcome.
You can help us translate the extension on Transifex.
