Responsive Design
Tailwind makes responsive design easy with breakpoint prefixes. Add `md:` or `lg:` before any class to apply it only at that screen size.
```html <!-- Stack on mobile, row on desktop --> <div class="flex flex-col md:flex-row gap-4"> <div class="w-full md:w-1/2">Left</div> <div class="w-full md:w-1/2">Right</div> </div> <!-- Hide on mobile, show on desktop --> <nav class="hidden md:flex gap-4"> <a href="/">Home</a> <a href="/about">About</a> </nav> ``` **Breakpoints:** - `sm:`: 640px and up - `md:`: 768px and up - `lg:`: 1024px and up - `xl:`: 1280px and up
