abyss-jellyfin

Project Overview

Abyss is a clean and minimal theme for Jellyfin with frosted glass surfaces, refined typography, smooth animations, and a minimal design language that re-skins JellyFin almost exhaustively.

Key Features

• One-click installer: Windows .exe and Linux .sh scripts auto-configure your Jellyfin instance, CSS, dashboard theme, home section order, and Spotlight
• Spotlight home banner: A cinematic banner showing your current Continue Watching item with backdrop image, metadata pills, and a resume play button
• Frosted glass UI: Header, drawer, dialogs, toasts, and footer use backdrop-filter blur
• Refined typography: Google Sans throughout with consistent weight and spacing
• Smooth transitions and animations: Carefully tuned easing with staggered fade-up entrance and spring pop animation for the favourite button
• Floating sidebar: Pill-shaped drawer with rounded corners and snappy slide animation
• Pill tab bar: Active tab highlighted with a filled pill indicator
• Every element targeted: Cards, indicators, sliders, checkboxes, form inputs, OSD, now playing bar, chapter thumbnails, search page, detail pages, and dashboard
• Responsive: Mobile layout tweaks, ultrawide support, and cast thumbnail scaling
• Customisable: Three CSS variables let you retheme without touching the rest
