I'll add a theme toggle to switch between the current style and a completely different skin with different fonts, icons, and colors.

I've added a theme toggle that switches between two completely different visual styles while keeping the same data. Here's what I implemented:

Theme Toggle Feature

1. Theme Toggle Button: Added a moon/sun icon button in the top right corner that switches between themes
2. Theme Provider: Created a context provider to manage theme state across components
3. Theme Persistence: Added localStorage support to remember the user's theme preference

Light Theme (Original)

• Blue gradient background
• Sans-serif font
• Clean, modern styling
• White and blue color scheme
• Standard icon styling

Dark Theme (Alternative)

• Dark purple gradient background
• Serif font (Playfair Display) with italic accents
• More dramatic styling with glow effects on icons
• Purple and amber color scheme
• Larger weather icons with drop shadows

Implementation Details

1. Component Theming:

   • Updated all components to accept a theme prop
   • Modified styling based on the current theme
   • Added conditional classes for colors, fonts, and effects

2. Icon Styling:

   • Created different color schemes for icons in each theme
   • Added glow effects to icons in dark mode
   • Adjusted icon sizes for better visibility in dark mode

3. Typography Changes:

   • Added serif font for the dark theme
   • Used italic styling for key elements in dark theme
   • Adjusted font weights and sizes for better readability

4. Color Palette Shift:

   • Changed from blue/white to purple/amber in dark mode
   • Modified all UI elements to use theme-specific colors
   • Adjusted opacity and contrast for better visibility

The toggle provides a completely different visual experience while maintaining the same functionality and data structure. Users can switch between themes at any time, and their preference will be remembered across sessions.

I'll reverse the theme toggle feature and return to the original single-theme design.

I've reversed the theme toggle feature and returned the app to its original single-theme design. Here's what was removed:

1. Theme Provider: Removed the ThemeProvider component and its context
2. Theme Props: Removed all theme-related props from components
3. Conditional Styling: Removed all theme-conditional styling from components
4. Toggle Button: Removed the theme toggle button from the header
5. Dark Theme Styles: Removed dark theme specific styles from globals.css
6. Font Imports: Removed the Playfair Display font import
7. Special Effects: Removed the glow effects and other theme-specific styling

The app now has its original appearance with:

• Blue gradient background
• Sans-serif font
• Standard icon styling
• Original color scheme

All components have been reverted to their previous implementations, and the app layout no longer wraps the content in a ThemeProvider. The weather app now maintains a consistent visual style without the ability to toggle between different themes.
