    Beautiful Scrollbar — Compact Dark UI (Instant Jump)

    Minimal, fast, and modern custom scrollbars for any page. Multi-container aware, themeable, and tuned for instant navigation.

    • Instant quick jumps: 1 = top (0%), 0 = bottom (100%), 2–9 = 20%–90%
    • Multi-container support: acts on the scrollable element under your mouse/focus
    • Minimal dark settings UI (ESC), glass overlay, red-close feedback
    • 10+ built-in themes, persisted with GM storage/localStorage
    • Near-zero overhead: rAF-based updates, observer cleanups, reduced redundancy

    Installation

    Option A: Paste into Tampermonkey

    1. Install Tampermonkey (Chrome/Edge/Firefox/Safari).
    2. Create new script → paste the provided userscript.
    3. Save. It runs on all sites at document-start.

    Option B: Import from file

    • Save the script to a file and import via Tampermonkey dashboard.

    Note: The script hides native scrollbars globally via CSS for a clean look.

    Usage

    • Press ESC to open/close the Themes panel.
    • Hover over a scrollable element (or focus it) to make it the “active container”.
    • The custom bar appears only when scrolling is possible and aligns with that container’s viewport.

    Keyboard Shortcuts

    Key Action Notes
    ESC Open/close settings Works when not typing in inputs
    1 Jump to top (0%) Instant
    0 Jump to bottom (100%) Instant
    2–9 Jump to 20%–90% Instant; number row or numpad

    Shortcuts are ignored while typing in inputs/contenteditable or when the settings UI is open.

    Settings UI

    • Open with ESC. Minimal dark panel with a glassy overlay.
    • Click any theme card to apply immediately.
    • Close button turns red on hover and deeper red on click.

    Themes and Customization

    Built-in themes include: Modern, Neon, Ocean, Sunset, Forest, Candy, Dark, Gold, Cyber, Ruby, Slate, and None.

    To change the default theme:

    • Open the settings (ESC) and select a theme; it’s saved automatically.
    • Or edit the script: set the initial storage value for key bs-theme to your desired theme.

    Advanced (developers):

    • Themes are defined in a THEMES object.
    • Each theme uses CSS variables applied to :root:
      • --bs-track (track), --bs-thumb (thumb), --bs-thumb-hover (hover), --bs-radius, --bs-width, --bs-glow
    • You can add your own theme by extending THEMES and selecting it in the UI.

    Multi-Container Behavior

    • The script tracks the active container from mouseover, wheel, and focus events.
    • Quick-jump keys operate on that active container.
    • Scrollbar instances are created on demand and cleaned up when elements are removed.

    Note: If content is inside an iframe, the userscript must run in that frame as well for an in-frame scrollbar.

    Performance

    • Instant scroll updates (no smooth scrolling for shortcuts).
    • Minimal layout work; updates are scheduled via requestAnimationFrame.
    • MutationObserver cleans removed instances efficiently.
    • Honors prefers-reduced-motion for UI transitions.
