Adding Tailwind CSS

There are usually two ways of adding Tailwind CSS to your HTML project.

Using the Tailwind CSS CDN
Adding Tailwind CSS in HTML via the package manager and using PostCSS to process the configuration file.

Tailwind CSS CDN

Adding the Tailwind CSS in an HTML project via the CDN is easier and very beginner friendly. This method allows you to use the Tailwind CSS framework without the need to worry about PostCSS configurations. It is a great way to jumpstart your project. However with these perks come some limitations, some of these limitations are:

You cannot install third-party plugins
You cannot customize Tailwind's default theme.
You get access to all the files even the files you do not need.
You cannot use any directives like @apply, or @variants.
You cannot enable additional variants like group-focus.

For the Tailwind's styles to work properly and to have a great experience with the Tailwind CSS framework, you need to use the HTML5 doctype and include the meta tags for responsiveness on all devices

html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
  </head>
  <body></body>
</html>

To use the Tailwind CSS in an HTML project via the CDN, add this to the head section of your HTML project.

html

<link href="https://unpkg.com/tailwindcss@^2/dist/tailwind.min.CSS" rel=" stylesheet" />

With the addition of the link above, you will get access to the Tailwind CSS classes that allow us to use its predefined styles in our projects.

Tailwind CSS using the Package Manager.

Now, I would suggest if you are building a world application, it would be best to install your tailwind CSS using the package manager. This is because most frameworks make use of PostCSS already, like the auto picker.

In this part of the Tailwind CSS tutorial, we are going to look at how to install Tailwind CSS in HTML using the package manager.

Prerequisites

To get the most out of this section of the tutorial, you need the following:

Node and its package manager, npm. You can install it from. Run the command node -v && npm -v to verify you have them installed.
Alternatively, we can use another package manager, .

Steps in installing tailwind CSS using package manager

Creating our package.json file
Install Tailwind CSS
Adding tailwind CSS directives to a CSS file
Setting up the Tailwind configuration file
Tailwind CSS Processing

Creating our package.json file

A package.json file is a file that lives in the root directory of our project. It holds important information about your project like the project's name, the project's description, dependencies required by the project, and how npm should run your project, etc.

To create a package.json file in your project, go to your terminal, and change the file directory to the folder you want your package.json file to be created in.

To change the file directory run this command in your terminal.

bash

cd <path to your folder>

Next, we run this npm or yarn ( if you decided to use the yarn package manager ) command.

bash

npm init

# or

yarn init

With this you would be asked a couple of questions, you can skip these questions by pressing the enter key.

Installing the latest Tailwind CSS

Next, we install the Tailwind CSS in the HTML project along with the latest PostCSS and autoprefixer using the command below

bash

npm install -D tailwindcss@latest postcss@latest autoprefixer@latest

Adding tailwind CSS directives to a CSS file

The next step in adding tailwind CSS in an HTML project is to create a file called main.css in the root folder of your application and write the following code to give your application the tailwind CSS utilities.

css

/* ./your-css-folder/main.css */

@tailwind base;
@tailwind components;
@tailwind utilities;

Setting up the Tailwind configuration file

Setting up Your Tailwind CSS configuration is an important step in adding Tailwind CSS to an HTML project.

The chances are that you would want to use your configuration when building your application. The configuration file makes it easy to customize the classes in Tailwind CSS by changing any fonts, color, spacing, etc.

To override the default classes when using Tailwind, run the following command in your terminal to create a tailwind.config.js file.

bash

npx tailwind css init

In the new config file, you can go ahead to configure them by writing the following code on them.

// tailwind.config.js
module.exports = {
  purge: [],
  darkMode: false, // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {},
  plugins: [],
};

Tailwind CSS Processing

The final step in adding Tailwind CSS in the HTML file using the package manager is to add plugins inside the configuration file and run them, which will process the configuration file and the style.css file.

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
};

Now, you can go ahead to run the following command on your terminal.

bash

next tailwind CSS build style.css –o output.css

This will generate a new CSS file called output.css. We then include this output.css file in our HTML file, the same way we include a normal CSS file by adding this line of code

html

<link href = “./output.CSS” rel = “stylesheet”>

With that, you can now use Tailwind CSS in the HTML project. you can go ahead to build your application.

Conclusion

In this Tailwind CSS tutorial, we covered how to add Tailwind CSS in an HTML file using different methods through the Tailwind CSS CDN and Package manager. With this information, You should be able to easily jump-start using this framework in a matter of minutes.
