        # Stylus

Stylus is a fork of Stylish for Chrome, also compatible with Firefox as a WebExtension

## Highlights

* 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](https://github.com/openstyles/stylus/wiki/Usercss)).

* 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.

## Releases

1. [Chrome Web Store](https://chrome.google.com/webstore/detail/stylus/clngdbkpkpeebahjckkjfobafhncgmne) or [beta](https://chrome.google.com/webstore/detail/stylus-beta/apmmpaebfobifelkijhaljbmpcgbjbdo)

2. [Firefox add-ons](https://addons.mozilla.org/firefox/addon/styl-us/) or [beta](https://github.com/openstyles/stylus/releases) (as an xpi file)

In Opera browser please use our extension from Chrome Web Store, see [the instruction](https://github.com/openstyles/stylus/wiki/Opera,-Outdated-Stylus).
