Introduction

Responsive design makes websites look good on all devices, big or small. It helps everyone use your site easily, no matter what screen they have.

When building a website that people will visit on phones, tablets, and computers.
When you want your site to be easy to read and navigate on any screen size.
When you want to reach more users by supporting different devices.
When you want to improve your website's search engine ranking, since search engines prefer mobile-friendly sites.
When you want to avoid making separate versions of your site for different devices.
Syntax
Tailwind
Use Tailwind CSS responsive prefixes like sm:, md:, lg:, xl:, 2xl: before utility classes.
Example: <div class="bg-blue-500 sm:bg-green-500 md:bg-red-500">Content</div>

Responsive prefixes apply styles at or above the specified screen size.

Tailwind uses a mobile-first approach, so unprefixed styles apply to all sizes unless overridden.

Examples
Text is normal size on small screens, larger on medium and bigger screens.
Tailwind
<div class="text-base md:text-lg">Hello</div>
Padding increases as screen size grows: small padding on mobile, bigger on tablets and desktops.
Tailwind
<button class="p-2 sm:p-4 lg:p-6">Click me</button>
Image takes full width on small screens, half width on medium and larger screens.
Tailwind
<img class="w-full md:w-1/2" src="image.jpg" alt="Example image">
Sample Program

This page shows a header and a section with text and a button. The text and button sizes grow bigger on larger screens using Tailwind's responsive prefixes.
