Implement Dark/Light Mode Toggle
đ Problem
Add a button that toggles a website between dark mode and light mode, and remembers the user's choice on their next visit.
đ§ Approach
Use a CSS class (like 'dark') on the <body> or <html> element that changes colors via CSS variables or Tailwind's dark: variants. On button click, toggle that class with JavaScript, and save the current choice to localStorage so it persists across page reloads.
