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.
- Chrome Web Store (or beta)
- Firefox add-ons
- Opera add-ons (see wiki for more recent version)
