How to Use This Tool

Create custom dark mode toggle switches with our comprehensive theme generator. This powerful tool helps you build accessible, responsive dark/light mode toggles with complete HTML, CSS, and JavaScript code.

Step 1: Choose Toggle Style
Select from four toggle styles: Switch (default checkbox style), Button (text-based toggle), Icon (sun/moon icons), or Custom HTML (bring your own markup). Each style offers different visual approaches for theme switching.

Step 2: Configure Sizing and Position
Set your toggle size (Small, Medium, or Large) for perfect proportion control. Choose positioning: Top Right, Top Left, Bottom Right, Bottom Left, or Inline for flexible layout integration.

Step 3: Customize Color Themes
Define complete color schemes for both light and dark modes. Set background, text, primary, and secondary colors for each theme. The live preview updates instantly as you adjust colors.

Step 4: Set Animation Preferences
Choose transition animations: None (instant change), Fade (smooth opacity transition), Slide (directional movement), or Scale (zooming effect). Enable smooth transitions for professional-quality theme switching.

Step 5: Configure Advanced Options
Respect system preference to automatically match user's OS theme setting. Save user preference with localStorage for persistent theme selection across sessions. All accessibility features are built-in.

Step 6: Export and Implement
Copy individual HTML, CSS, or JavaScript code snippets from the tabbed interface. Download complete zip files with all necessary assets. Test your toggle in a new window before implementation.
