Usage

For both of the below installation methods, you will need the Stylus browser extension installed. Install Stylus for Chrome or Firefox. If you use Chrome, make sure to enable “Allow access to file URLs” in the Chrome extension settings for Stylus (visit chrome://extensions/?id=clngdbkpkpeebahjckkjfobafhncgmne).

  1. Download the compiled Stylus export file, containing our recommended Stylus settings and all userstyles preloaded: import.json (download).
    • Alternatively, if you want to further customize the import.json file - such as setting it so that all userstyles have the accent color peach, or the dark flavor is always frappe - you can download a customized Stylus export file from @uncenter’s “Catppuccin Userstyles Customizer” instead.
  2. Open the Stylus “manage” page.
  3. On the sidebar panel, click the Import button in the Backup section, and select the downloaded file from step 1.
  1. Enable CSP Patching from Stylus’s Settings > Advanced.
  2. Install your choice of available userstyles by clicking the Stylus Install badge in each README.

All userstyles come with three default configuration options; the light flavor, the dark flavor, and the accent color. Some userstyles may offer additional site-specific options as well.

For decentralized or self-hosted applications, you can apply a theme to one or multiple instances across updates by following the instructions below.

  1. Open the Stylus “Manage” page.
  2. Click on the userstyle’s name in the list.
  3. Click on Style settings in the left panel.
  4. Enter the URL patterns for your instance(s) in the text box labeled Custom included sites. For example, to apply a userstyle to example.org, you would add a line with https://example.org/* to the textbox. The trailing asterisk applies it to all pages on the domain - without it, only the root page is themed.
