To install Tailwind CSS, you'll need to start by installing the Tailwind CSS package using npm or yarn. You can do this by running the command npm install tailwindcss or yarn add tailwindcss in your terminal.
Tailwind CSS is a utility-first CSS framework that allows you to write more concise and maintainable CSS code. By using utility classes, you can style your HTML elements without writing custom CSS.
To use Tailwind CSS, you'll need to create a postcss.config.js file in the root of your project. This file will configure PostCSS to process your CSS files and apply the Tailwind CSS utility classes.
Next, you'll need to create a tailwind.config.js file to configure Tailwind CSS. This file will allow you to customize the colors, spacing, and other settings for your project.

Installation Methods
You can install Tailwind CSS using various methods, including npm and the Tailwind CLI.
To install Tailwind CSS via npm, you'll need to have Node.js and npm installed. You can download Node.js from the official website, which will include npm. Once you have Node.js and npm set up, you can install Tailwind CSS into your project via npm by running the command `npm install tailwindcss -D` in your project directory.

Installing Tailwind CSS as a PostCSS plugin is another option. This method requires Node.js 12.13.0 or higher. Most modern frameworks use PostCSS under the hood already, so you may already be using other PostCSS plugins like autoprefixer.
If you're looking for a quick and easy way to try out Tailwind CSS, you can use the CDN build. However, keep in mind that the CDN build is large and not representative of the sizes you see when including Tailwind as part of your build process.
Here are the installation methods summarized:
Using the Tailwind CLI is also an option, which involves installing the libraries and compiling the final CSS code. This method is recommended if you want to use Tailwind CSS more seriously and take advantage of its advanced features.
Setup
To get started with Tailwind CSS, you need to set it up correctly. You can do this by running a command that generates a configuration file.
This command generates tailwind.config.cjs and postcss.config.cjs configuration files, also known as config files. They help you interact with your project and customize everything.
You can customize what Tailwind generates by creating a tailwind.config.js file using the Tailwind CLI tool. This file will automatically be read when building your CSS with Tailwind CLI.
To set up the Tailwind configuration file, you need to run a command that generates a new configuration file called tailwind.config.js. This file will contain the initial configuration settings.
After the installation, you can generate your tailwind.config.js file by running a command. This creates a tailwind.config.js file in your project root.
Including in Your Project
Including Tailwind in your project can be done in several ways. You can create a new CSS file, such as styles.css, and use the @import directive to include Tailwind's base, components, and utilities styles.
To include Tailwind in your CSS, create a CSS file if you don’t already have one, and use the @tailwind directive to inject Tailwind’s base, components, and utilities styles. This directive will be swapped by the actual Tailwind CSS classes when using PostCSS later in this guide.

If you’re using postcss-import or a tool that uses it under the hood, use Tailwind’s imports instead of the @tailwind directive to avoid issues when importing any of your own additional files. This is especially important if you’re working on a project with a lot of custom CSS files.
You can also skip creating a CSS file altogether and import tailwindcss/tailwind.css instead, which has all of these directives already in place. This is a great option if you’re working in a JavaScript framework like React or Vue that supports directly importing CSS files into your JS.
Basic Usage and Process
To set up Tailwind CSS, you can add a build script to your package.json file. This script will allow you to run npm run build to build your CSS.
You can also run Tailwind CSS from within your terminal to build your CSS files. The CLI is already installed from previous steps.
Here are some key classes to know when creating a basic layout with Tailwind CSS:
- max-w-md: sets the maximum width of the element to 24rem.
- mx-auto: centers the element horizontally.
- bg-white: sets the background color of the element to white.
- rounded-xl: gives the element rounded corners.
- shadow-md: applies medium box shadow to the element.
- overflow-hidden: clips any child content or padding that goes outside the bounds of the element.
- m-5: applies 1.25rem margin on all four sides of the element.
Basic Layout
Creating a basic layout with Tailwind CSS is a great way to get started with the framework. You can use classes like max-w-md to set the maximum width of an element to 24rem.
To center an element horizontally, use the mx-auto class. This will give you a clean and simple layout.
The bg-white class sets the background color of an element to white, while rounded-xl gives the element rounded corners. Shadow-md applies a medium box shadow to the element, and overflow-hidden clips any child content or padding that goes outside the bounds of the element.
Some other useful classes for basic layouts include m-5, which applies 1.25rem margin on all four sides of an element.

You can also run Tailwind CSS from within your terminal to build your CSS files. The command to do this is already installed and ready to use.
To include Tailwind CSS in your HTML using the recommended PostCSS method, you'll need to add some code to your configuration file. This will generate a new CSS file called output.css, which you can then include in your HTML file.
Here's a step-by-step guide to processing your CSS:
1. Add a build script to your package.json file.
2. Run npm run build to build your CSS.
3. Alternatively, use the Tailwind CSS CLI to build your CSS files.
4. Add the necessary code to your configuration file.
5. Run the command to process your files and generate output.css.
6. Include output.css in your HTML file.
Some useful commands to know include running npm run build and using the --watch flag to automatically rebuild your CSS when changes are made.
