Tailwind CSS is a utility-first CSS framework designed for rapid UI development. Instead of providing pre-built components, it offers low-level utility classes that let you build custom designs without ever leaving your HTML.

Utility-first CSS is an approach where you use small, single-purpose classes to build your user interface. These utility classes are composed to create complex designs directly in the HTML, rather than relying on custom CSS. This approach favors composition over inheritance, making it easier to maintain and scale your codebase.

To install Tailwind CSS, you can use npm or yarn by running the following commands:

Using npm:

npm install tailwindcss

Using yarn:

yarn add tailwindcss

After installing, create a configuration file called tailwind.config.js in your project's root directory using the following command:

npx tailwindcss init

In your project's CSS file, import Tailwind's base styles, components, and utilities using the @import directive:

@import 'tailwindcss/base';
@import 'tailwindcss/components';
@import 'tailwindcss/utilities';
