From 0446202b239cc8db5302f2cd839a2ea31da19dd4 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 24 Feb 2026 13:33:08 +0000 Subject: [PATCH] Fix theme switching robustness and add a11y improvements - Updated `app/globals.css` to include `color-scheme: light/dark` for system UI elements. - Updated `app/layout.tsx` to use CSS variable `bg-[var(--background)]` for the body, ensuring consistent background color switching. - Restored `darkMode: "class"` in `tailwind.config.ts` to ensure compatibility with manual theme toggling. - Added `aria-label` to the theme toggle button in `components/Sidebar.tsx` for accessibility.

Using CSS variables (`bg-[var(--background)]`) that are scoped in `:root` and `.dark` blocks is more robust because it relies on standard CSS inheritance, ensuring the background color always matches the active theme class on the document root. Also, adding `color-scheme: dark` is critical for native UI elements (scrollbars) to match. +**Action:** When implementing dark mode, always define `color-scheme` in CSS and prefer CSS variables for the main background to avoid "flash" or mismatch issues. diff --git a/app/globals.css b/app/globals.css index d7efd95..ffb095d 100644 --- a/app/globals.css +++ b/app/globals.css @@ -79,11 +79,13 @@ /* Base styles */ :root { + color-scheme: light; --background: #f6f6f8; --foreground: #0f172a; } .dark { + color-scheme: dark; --background: #000000; --foreground: #ffffff; } diff --git a/app/layout.tsx b/app/layout.tsx index 268f65e..7f31992 100644 --- a/app/layout.tsx +++ b/app/layout.tsx @@ -38,7 +38,7 @@ export default function RootLayout({ - + {children} diff --git a/components/Sidebar.tsx b/components/Sidebar.tsx index 04f5f07..b34e873 100644 --- a/components/Sidebar.tsx +++ b/components/Sidebar.tsx @@ -78,6 +78,7 @@ export function Sidebar() {
