Tailwind is a utility CSS library that has been gaining a lot of popularity in the past few years. Utility libraries are great because you won't end up fighting against a framework when it comes to building your own custom designs. And with Tailwind, you can build your sites faster because you won't be jumping between your HTML and CSS all the time. In this tutorial, we're going to learn how to add TailwindCSS to a Hugo project. Prefer video? We’ve got that too https://www.youtube.com/watch?v=so3VZwdWcBg Prerequisites To follow along with this tutorial, you will need to have and installed Hugo NodeJS Installation guides: Hugo: https://gohugo.io/getting-started/installing/ NodeJS: https://nodejs.org/en/download/ Creating Hugo Project and Theme Let's start by creating a new project. Navigation into the directory where you keep all your projects, and run the command to create a new hugo site. We're going to name our site . "hugotails" cd Sites
hugo new site hugotails Then change directories into our new site and create a new theme. We will call the theme . "hugotails" "windytheme" cd hugotails

hugo new theme windytheme Initialising NPM and installing dependencies Now that we've got our hugo site all ready to go, let's install tailwind. To follow along with this section of the tutorial, you will need to have Nodejs installed. So if you haven't installed it already, you might want to do so before continuing. Make sure you're in the project root because we will be initialising NPM here. We can run the command with the flag so we don't have to go through all the setup questions. "hugotails" npm init --yes After this command is successfully run, we will have a newly-created in our project root. package.json npm init --yes Now that our project has been initialised with NPM, we can go ahead and install the necessary packages. Run: npm install --save-dev autoprefixer postcss postcss-cli postcss-import tailwindcss We are passing in the flag because we want to save these packages as dev dependencies. -save-dev If you noticed, we aren't just installing the tailwind package, we have a few other accompanying packages. Below is a brief description of what each of them are for: - a tool for transforming CSS with JavaScript. Postcss - the command-line tool we can use to execute Postcss commands in the terminal postcss-cli - used to resolve the path of an @import rule postcss-import - helps us add vendor prefixes to our CSS autoprefixer - a library of utility classes to help us build unique custom layouts without doing too much tailwindcss Setting up config files Next up, we will tell our site to use our new theme, by adding the following line to our file: windytheme hugotails/config.toml ...
theme = "windytheme" Now we can move onto adding tailwind as a PostCSS plugin. Since we're working with a brand new theme, we don't have a directory yet. Let's create one. Running mkdir with the flag will create nested directories if they don't already exist. css -p mkdir -p themes/windytheme/assets/css/ Next we need to create configuration files for both PostCSS and tailwind. We will also need a main file: styles.scss touch themes/windytheme/assets/css/postcss.config.js
touch themes/windytheme/assets/css/tailwind.config.js
touch themes/windytheme/assets/css/styles.scss Let's tackle the postcss config first. Open up the file postcss.config.js const themeDir = __dirname + '/../../';

module.exports = {    
    plugins: [   
        require('postcss-import')({
            path: [themeDir]
            }), 
        require('tailwindcss')(themeDir + 'assets/css/tailwind.config.js'),
        require('autoprefixer')({
            path: [themeDir]
        }),
    ]
} Phew, that was a lot. But we're not done yet, let's head over to our and add a basic configuration file for TailwindCSS: tailwind.config.js module.exports = {
  theme: {
    extend: {}
  },
  variants: {},
  plugins: []
} Updating styles.scss Now we have to include the necessary tailwind imports in our stylesheet. Open up our stylesheet, , and add the following imports: styles.scss @import "node_modules/tailwindcss/base";
@import "node_modules/tailwindcss/components";
@import "node_modules/tailwindcss/utilities"; Importing CSS in head tag When we created our new theme, Hugo helped us out by creating some starting templates files. One of these starter files is the partial. head.html {{ $styles := resources.Get "css/styles.scss" | toCSS | postCSS (dict "config" "./assets/css/postcss.config.js") }}
{{ if .Site.IsServer }}
  <link rel="stylesheet" href="{{ $styles.RelPermalink }}">
{{ else }}
  {{ $styles := $styles | minify | fingerprint | resources.PostProcess }}
  <link rel="stylesheet" href="{{ $styles.Permalink }}" integrity="{{ $styles.Data.Integrity }}">
{{ end }} So what's going on in our code above? Let's go over it line-by-line: - We got our stylesheet as a resource and stored it in a variable called styles $styles := resources.Get "css/styles.scss" - We used Hugo pipes to first convert the SCSS file to CSS, so the browser can understand it | toCSS - We point to where our PostCSS config file lives | postCSS (dict "config" "./assets/css/postcss.config.js") We're going to check if we're in our local dev environment by using the IsServer variable, if we are, we will link to the stylesheets relative URL However, if we're in a production environment, we're going to use Hugo Pipes to minify our css file We also want to pipe it through fingerprint so that we know the asset has not been tampered with. This also has a nice side-effect of cache-busting, so we also know we're serving the latest version Testing some TailwindCSS classes We've set up all the configuration we need. Now let's set up our page too. This file can be found at . index themes/windytheme/layouts/index.html {{ define "main" }}
  {{ .Content }}
{{ end }} Now we can imported our styles and transformed them in a few useful ways, let's see if everything actually works. Let's create a basic header in the file: themes/windytheme/layouts/partials/header.html <header>
  <h1>Welcome to HugoTails!</h1>
</header> While still in , let's add some tailwind utility classes: themes/windytheme/layouts/partials/header.html <header class="w-full bg-red-300">
  <h1 class="text-center">Welcome to HugoTails!</h1>
</header> We should also start our Hugo server: hugo server Open your browser and visit , you should be able to see your changes there. http://localhost:1313 Conclusion In this tutorial, you learnt how to add tailwindcss to your hugo site using Hugo Pipes.
