Installation for Mastodon admins

Install Tangerine UI as the only theme on your instance:

• Copy & paste the contents of TangerineUI.css to the Custom CSS field in the administration panel on your Mastodon instance (Navigate to https://domain/admin/settings/appearance).
  • 🪻 For the purple variant, copy the contents of TangerineUI-purple.css instead.

⚠️ Caution: Using the 'Custom CSS' field to apply Tangerine UI will prevent all users on your instance from being able to choose another theme in their Appearance settings (see Accessibility). Please make sure there is a consensus among your users for doing so. If not, see below how to install Tangerine UI as an optional theme for your users.

Install Tangerine UI as an optional theme on your instance [Recommended]:

Follow these instructions if you wish to add Tangerine UI as an available theme for your users on your instance.
This will also allow you to set Tangerine UI as the default theme for your instance, while still letting your users change back to any of Mastodon's default themes in their Appearance settings.

1. Copy the files from mastodon/app/javascript/styles/ in this repository to your Mastodon themes directory app/javascript/styles/:

# Where $REPO is this repository, and $INSTALLDIR is your Mastodon installation.
cp -r $REPO/mastodon/app/javascript/styles/* $INSTALLDIR/app/javascript/styles

2. Add Tangerine UI to themes.yml. To make Tangerine UI available in your users's settings, you need to add a new line to config/themes.yml. Here we're adding 2 new lines, one for Tangerine UI, another for Tangerine UI's purple variant:

default: styles/application.scss
contrast: styles/contrast.scss
mastodon-light: styles/mastodon-light.scss
tangerineui: styles/tangerineui.scss                  | **new**
tangerineui-purple: styles/tangerineui-purple.scss    | **new**

3. Add a localized name (optional). You can edit each desired language's locale file in config/locales/[lang].yml to add a localized string name for Tangerine UI. You need to do this for every language you expect your users to use. Otherwise, in their themes list, they will see the unlocalized theme name ("tangerineui-purple"), instead of a readable theme name ("Tangerine UI (Purple)").

themes:
  contrast: Mastodon (High contrast)
  default: Mastodon (Dark)
  mastodon-light: Mastodon (Light)
  tangerineui: Tangerine UI                           | **new**
  tangerineui-purple: Tangerine UI (Purple)           | **new**

4. Compile theme assets and restart. Run RAILS_ENV=production bundle exec rails assets:precompile and restart your Mastodon instance for the changes to take effect.

Your users should now be able to choose 'Tangerine UI' and 'Tangerine UI (Purple)' as their site theme:

As an admin, you should also now be able to set Tangerine UI as the default theme for your instance (navigate to https://domain/admin/settings/appearance):

Installation for Glitch-soc admins

Tangerine UI does not yet support Glitch-soc's features and layout, but it can still be installed as a vanilla skin on your Glitch-soc instance:

1. Copy the files from mastodon/app/javascript/styles/ in this repository to your Mastodon themes directory app/javascript/styles/:

# Where $REPO is this repository, and $INSTALLDIR is your Glitch-soc installation.
cp -r $REPO/mastodon/app/javascript/styles/* $INSTALLDIR/app/javascript/styles

2. Copy the files from mastodon/app/javascript/skins/vanilla/ in this repository to your Glitch-soc skins directory app/javascript/skins/vanilla/:

# Where $REPO is this repository, and $INSTALLDIR is your Glitch-soc installation.
cp -r $REPO/mastodon/app/javascript/skins/vanilla/* $INSTALLDIR/app/javascript/skins/vanilla

3. Compile theme assets and restart. Run RAILS_ENV=production bundle exec rails assets:precompile and restart your Glitch-soc instance for the changes to take effect.

Your users should now be able to select Tangerine UI as a theme in their settings, under Flavours → Vanilla Mastodon → Skin

Installation for regular users

Even if you are not an admin on your instance, you can still use Tangerine UI with a browser extension:

1. Install any browser extension that allows you to inject CSS on a webpage, such as Stylus, or Live CSS Editor
2. Copy & paste the contents of TangerineUI.css to the extension's editor
   • 🪻 For the purple variant, copy the contents of TangerineUI-purple.css instead.

⚠️ If you are a user on a Glitch-soc instance, you must switch to the Vanilla Mastodon flavour for Tangerine UI to work properly: in your instance settings, navigate to Flavours → Vanilla Mastodon → select the 'Default' skin.

💡 Alternatively, if you wish to use a JavaScript browser extension, @Write has written a ready-to-use UserScript to load Tangerine UI on any Mastodon instance. Check out the TangerineUI-Userscript repository for instructions.

Things to know

• Tangerine UI currently only supports Mastodon's single column layout. The advanced web interface (multiple columns) will not be affected.
• Tangerine UI auto-switches from light to dark mode based on your OS preference.
• Check your Mastodon instance version before using. The latest Mastodon release checked to be compatible is indicated in the CSS file header.

Accessibility

Please consider that some of your users may depend on Mastodon's High Contrast theme before setting Tangerine UI as the only theme on your instance. For this reason, unless you're running a single-user instance, I recommend installing Tangerine UI as an optional/revertable theme instead.
