This Firefox extension replaces the CSS styles on Lemmy instances to create a modern looking theme. Works with Lemmy 0.17 and 0.18 (other versions haven't been tested).
https://addons.mozilla.org/firefox/addon/lemmy-modern-ui-theme
Install dependencies:
npm install
Build the addon:
npm run build
You can build the CSS styles to use them on your Lemmy instance (you can also get them from Releases page):
npm run build-theme
The following files will appear in the dist folder:
modern-light.css - light theme only
modern-dark.css - dark theme only
modern-auto.css - contains both themes and switches between them automatically depending on user's current system settings (the default Lemmy theme works the same way)
In order to use the theme on your instance, put the chosen CSS files into the extra_themes folder or follow the documentation.
