I'll fix the dark/light theme toggle to work properly with Tailwind CSS's class-based dark mode. Let me gather the current state of the project first:
Now let me check the current ThemeProvider and Header components:
I can see the issue. The current setup uses CSS variables for theming, but doesn't have explicit light/dark mode colors. I need to:
Let me fix all of this:
Now let me update the globals.css with proper light and dark mode color schemes:
Now let me update the ThemeProvider to properly handle hydration and fix the theme application:
Now let me update the layout to suppress hydration warnings and ensure the theme is applied before rendering:
Now let me also add a script to the layout that applies the theme before any content renders to prevent flash:
I've now completed a full fix for the dark/light theme toggle. Here's what I implemented:
Tailwind Config: Created a proper tailwind.config.ts with darkMode: 'class' to enable class-based dark mode switching.
Color Scheme: Updated globals.css with explicit light (white backgrounds, dark text) and dark (dark backgrounds, white text) color palettes using HSL variables that work with Tailwind's theming system.
ThemeProvider: Refactored to properly manage theme state, apply the "dark" class to the <html> element immediately, and persist the selection to localStorage using the key commbridge-theme.
Layout & Hydration: Added suppressHydrationWarning to the html element and injected a script tag that runs before any content renders, checking localStorage and system preferences to apply the theme instantly, preventing any flash of wrong-colored content.
Header Toggle: The existing toggle button with Sun/Moon icons now correctly switches between light and dark modes with immediate visual feedback. The theme persists across page refreshes and respects system preferences on first visit.
Fix dark/light theme using next-themes.
I see the issue - the Header component is being used at the top level but the ThemeProvider isn't properly wrapping it. Let me fix this by implementing next-themes properly. First, let me check the current structure:
I can see that next-themes is already installed in the project. Now I'll replace the custom ThemeProvider with next-themes, create a proper ThemeToggle component, and update the layout. Let me start:
Now let me delete the old ThemeProvider and create a new ThemeToggle component:
Now let me create the ThemeToggle component:
Now let me update the Header component to use the new ThemeToggle:
I've successfully replaced the custom theme implementation with next-themes. Here's what I changed:
layout.tsx: Replaced the custom ThemeProvider with next-themes using attribute="class", defaultTheme="dark", and enableSystem to respect system preferences. Removed the problematic inline script and suppressHydrationWarning is no longer needed.
ThemeToggle.tsx: Created a new client component that uses useTheme() from next-themes with a mounted check to prevent hydration mismatches. It provides instant theme switching with Sun/Moon icons.
Header.tsx: Updated to import and use the new ThemeToggle component instead of the custom theme hook, simplifying the code and eliminating the context error.
The theme now persists automatically via next-themes' localStorage integration, toggling works instantly without page refresh, and light/dark styles are properly applied via the "class" attribute on the html element.
