CSS LightDark Mode Toggle Generator
The CSS Light/Dark Mode Toggle Generator helps you create a responsive, customizable theme switcher for light and dark modes. It offers prebuilt toggle styles and theme variables, allowing you to desi gn, preview, and export a fully functional toggle switch with HTML, CSS, and JavaScript—all in one place.
How to Use This Tool
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.
