Fluent Scrollbars.

This feature modernizes the Chromium scrollbars (both overlay and non-overlay) on Windows and Linux to fit the Windows 11 Fluent design language.

concepts

  1. Fluent Scrollbars

    Chrome on Windows renders scrollbars with the Fluent design language to match the OS. Cosmetic but a big perceived-quality bump.

  2. Author overrides

    Sanity check for every existing site: do scrollbar-width and scrollbar-color still win over the new UA default? Three side-by-side scrollers, three override strategies.

  3. Density Explorer

    Three densities (auto/thin/none) and a colour-pair picker for scrollbar-color in one workshop. Branded, dark, and default presets, plus computed-style readouts to verify the cascade.

  4. Scrollbar Audit

    Paste CSS with scrollbar rules. The auditor classifies each rule (standard vs webkit vs none), checks whether it overrides the Fluent UA default, renders live preview scrollers, and generates a compatibility report showing which selectors correctly theme scrollbars in Chrome 136.
