Configuring TailwindCSS

The TailwindCSS settings for this system are very basic. But there are a few settings to note.

tailwind.css

Because TailwindCSS uses Normalize.css to set sensible defaults for all browsers, we lose basic formatting on many top level elements like Headers, <a> and <p> tags, etc. So you’ll want to set your own overrides in the /src/assets/css/tailwind.css file. Here are the current settings for this system as of the writing of this post.

/* /src/assets/css/tailwind.css  */
@tailwind base;

h1,
h2,
h3,
h4,
h5,
h6 {
	@apply font-semibold text-gray-700;
}
h1 {
	@apply text-4xl;
}
h2 {
	@apply pt-12 text-3xl;
}
h3 {
	@apply text-2xl;
}
h4 {
	@apply text-xl;
}
h5 {
	@apply text-lg;
}
p a,
li a,
blockquote a,
dd a {
	@apply font-medium text-indigo-700;
}
p {
	@apply mt-4;
}
.wrapper > p:first-of-type {
	@apply p-0 m-0;
}

	@apply pt-4 ml-8 list-decimal;
}
ul {
	@apply pt-4 ml-8 list-disc;
}
blockquote {
	@apply pl-4 m-4 border-l-4 border-gray-500;
}
code {
	@apply p-1 text-sm bg-gray-200 border border-gray-300 rounded-lg;
}
pre code {
	@apply bg-transparent border-0 rounded-none;
}

@tailwind components;

@tailwind utilities;

tailwind.config.js

This system also uses TailwindCSS’ built-in support for PurgeCSS. And because the system uses _data files to control some CSS classes, we have to include them in the /tailwind.config.js settings file so those CSS classes are NOT purged.

And while we’re in the /tailwind.config.js file, let’s take a peek at those custom theme height values that were setup to allow Editors to control the Hero and Featured Images heights:

(always check the TailwindCSS Release Notes page for info on the other settings.)

// /tailwind.config.js
const defaultTheme = require('tailwindcss/defaultTheme')

module.exports = {
	purge: [
		'./src/**/*.html',
		'./src/**/*.njk',
		'./src/**/*.md',
		'./src/_data/colors.js',
		'./src/_data/structure.js',
	],
	experimental: {
		applyComplexClasses: true,
	},
	future: {
		removeDeprecatedGapUtilities: true,
	},
	theme: {
		extend: {
			// created my own heights so can specify for Heros
			height: (theme) => ({
				'1/2': '50vh',
				'3/4': '75vh',
				'9/10': '90vh',
				'1/1': '100vh',
				'1/3': 'calc(100vh / 3)',
				'1/4': 'calc(100vh / 4)',
				'1/5': 'calc(100vh / 5)',
			}),
		},
	},
	variants: {},
	plugins: [require('@tailwindcss/forms')],
}
