Abyss
by AumGupta
Previews
Abyss is a clean, minimal dark theme for Jellyfin built around frosted glass surfaces, refined typography, and smooth animations that re-skin nearly the entire interface.
It ships with one-click installers for Windows and Linux that configure your whole Jellyfin instance (CSS, dashboard theme, home section order, and Spotlight) in one step, alongside a lighter “Lite” mode that keeps the same look while reducing blur, shadows, and motion. Accent color and corner rounding can be customized via CSS variables.
Installation instructions
Abyss’s full setup (one-click installer, dashboard theme, Spotlight) is described in the installation guide.
For a quick CSS-only preview, paste into a Custom CSS box:
@import url('https://cdn.jsdelivr.net/gh/AumGupta/abyss-jellyfin@main/abyss.css');Note: This quick import only gives a partial preview. Follow the full setup guide above for the complete experience.
