What is Stylus used for?

Stylus is a Chrome extension that lets you apply custom CSS styles to websites. You can install userstyles from repositories like Stylebots or userstyles.org, write your own CSS, or import styles created by others. It is commonly used for dark mode, custom site themes, and removing unwanted page elements.

What is the best Stylus alternative for Chrome?

The best alternative depends on your goal. For automatic dark mode, Dark Reader is a practical option. For very small personal tweaks, browser bookmarks or built-in CSS snippets may be enough. Stylus itself remains a maintained and widely-used tool for full custom CSS control.

Is Dark Reader a Stylus alternative?

Dark Reader is not a direct Stylus alternative. Dark Reader automatically applies dark mode to websites, while Stylus lets you write and apply any custom CSS. If your main goal is dark mode, Dark Reader is simpler. If you want full CSS control and custom site modifications, Stylus is the right tool.

Can I use custom CSS in Chrome without an extension?

Chrome does not have a built-in way to apply custom CSS to websites. Browser bookmarklets can run small CSS snippets as one-off actions, but they are not a replacement for a full userstyle manager like Stylus. For persistent custom styles across sites, a dedicated extension is needed.

Userstyles are generally safe when sourced from well-known repositories like Stylebots or userstyles.org and reviewed before enabling. However, styles from unknown mirrors or abandoned repositories may contain unwanted code, break site layouts, or have maintenance gaps. Review a style's rules and site match patterns before enabling it broadly.

Can userstyles break websites?

Yes. Poorly written or outdated userstyles can conflict with a website's own CSS, causing broken layouts, missing elements, or incorrect formatting. Use per-site disable controls to quickly fix issues, and remove or disable styles that consistently cause problems.

What happened to Stylish?

The original Stylish extension was removed from the Chrome Web Store after researchers discovered it was collecting users browsing history. Stylus was created by the community as a privacy-respecting replacement without data collection.

Yes. Stylus is an open-source extension that does not collect any user data. It is widely used and recommended by users who prefer transparent extension code as a replacement for Stylish.

Can I use Stylish styles with Stylus?

Yes. Stylus is compatible with styles written for Stylish. Most userstyles from userstyles.org work with Stylus without modification.

How do I migrate from Stylus?

Export your active styles from Stylus (Options > Styles > Export). List which sites you need styles for and whether you need full CSS control or just dark mode. For dark mode, try Dark Reader or built-in browser settings. For full CSS control, keep Stylus or find an actively maintained alternative. Test replacements on non-critical sites before switching fully.

Quick Answer

Stylus is a Chrome extension available on the Chrome Web Store for applying custom CSS and userstyles to websites. It is actively maintained as an MV3 extension.

Who Should Choose Which Option

Stylus

Browser bookmarks/snippets

You only need very small personal tweaks occasionally and want no extension overhead.

Unknown style mirrors

Common Failed Fixes

Trying to: Install userstyles from unknown mirrors

Why it does not work: Styles from unknown sources may contain unwanted code, break site layouts, or have outdated selectors that no longer work.

Safer alternative: Use styles from well-known repositories like Stylebots or userstyles.org. Review styles before enabling.

Trying to: Enable many overlapping styles on the same site

Why it does not work: Multiple styles targeting the same site can conflict, producing duplicate or broken styles.

Safer alternative: Disable overlapping styles. Use per-site enable and disable controls to manage active styles.

Trying to: Ignore site match patterns

Why it does not work: Styles with overly broad match patterns can apply to unintended sites, causing unexpected visual changes.

Safer alternative: Review and adjust match patterns so styles only apply where intended.

Trying to: Use abandoned styles without reviewing them

Why it does not work: Styles that are no longer maintained may have outdated CSS that breaks current site layouts.

Safer alternative: Review abandoned styles before keeping them enabled. Remove or replace styles that consistently cause problems.
