Tailwind CSS Skill

Tailwind CSS is a utility-first CSS framework that enables rapid UI development by providing pre-built utility classes. It generates optimized CSS at build-time by scanning your project files, resulting in zero runtime overhead and minimal production bundles.

When to Use This Skill

Use this skill when:

  • Building responsive layouts with mobile-first design
  • Implementing dark mode and theme customization
  • Creating custom design systems with consistent spacing, colors, and typography
  • Styling React, Vue, Svelte, or any web framework components
  • Prototyping interfaces with rapid visual feedback
  • Building production applications with optimized CSS bundles
  • Working with state-based styling (hover, focus, disabled, etc.)
  • Creating complex layouts with Grid and Flexbox utilities

Core Concepts

Utility-First Approach

Tailwind provides low-level utility classes that you apply directly to HTML elements instead of writing custom CSS:

<!-- Traditional CSS approach -->
<div class="card">
	<h2 class="card-title">Title</h2>
</div>

<!-- Tailwind utility-first approach -->
<div class="rounded-lg bg-white p-6 shadow-md">
	<h2 class="text-2xl font-bold text-gray-900">Title</h2>
</div>

Benefits:

  • No CSS file switching - styles live with markup
  • No naming conventions needed
  • Automatic dead code elimination
  • Consistent design tokens across team
  • Fast iteration without CSS bloat

Build-Time Processing

Tailwind scans your source files at build-time and generates only the CSS classes you actually use:

// Tailwind analyzes these files
content: [
	"./src/**/*.{js,jsx,ts,tsx}",
	"./app/**/*.{js,jsx,ts,tsx}",
	"./components/**/*.{js,jsx,ts,tsx}",
];

Result: Optimized production bundles with zero runtime overhead.

Installation & Setup

Modern Setup with Vite

Step 1: Install dependencies

npm install -D tailwindcss @tailwindcss/vite
# or
pnpm add -D tailwindcss @tailwindcss/vite
# or
yarn add -D tailwindcss @tailwindcss/vite

Step 2: Configure Vite

// vite.config.ts
import { defineConfig } from "vite";
import tailwindcss from "@tailwindcss/vite";

export default defineConfig({
	plugins: [tailwindcss()],
});

Step 3: Import in CSS

/* src/index.css */
@import "tailwindcss";

Step 4: Reference stylesheet in HTML

<!DOCTYPE html>
<html>
	<head>
		<link rel="stylesheet" href="./src/index.css" />
	</head>
	<body>
		<div class="bg-blue-500 p-4 text-white">Hello Tailwind!</div>
	</body>
</html>

Framework-Specific Setup

Next.js (App Router):

npx create-next-app@latest --tailwind

Next.js (Manual):

// tailwind.config.js
module.exports = {
	content: ["./app/**/*.{js,ts,jsx,tsx}", "./components/**/*.{js,ts,jsx,tsx}"],
};

React with Vite:

npm create vite@latest my-app -- --template react
npm install -D tailwindcss @tailwindcss/vite

Vue:

npm install -D tailwindcss @tailwindcss/vite

Svelte:

npm install -D tailwindcss @tailwindcss/vite

Astro:

npx astro add tailwind

PostCSS Setup (Alternative)

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p
// postcss.config.js
export default {
	plugins: {
		tailwindcss: {},
		autoprefixer: {},
	},
};

Design System & Tokens

Default Design System

Tailwind includes a comprehensive default design system:

  • Colors: 18 color palettes with 11 shades each (50-950)
  • Spacing: Consistent scale from 0.25rem to 96rem
  • Typography: Font sizes, weights, line heights
  • Breakpoints: Mobile-first responsive system
  • Shadows: Elevation system for depth
  • Border radius: Rounded corners at different scales

Customizing Theme

Use the @theme directive in CSS:

@import "tailwindcss";

@theme {
	/* Custom colors */
	--color-brand-50: oklch(0.97 0.02 264);
	--color-brand-500: oklch(0.55 0.22 264);
	--color-brand-900: oklch(0.25 0.15 264);

	/* Custom fonts */
	--font-display: "Satoshi", "Inter", sans-serif;
	--font-body: "Inter", system-ui, sans-serif;

	/* Custom spacing */
	--spacing-18: calc(var(--spacing) * 18);
	--spacing-navbar: 4.5rem;

	/* Custom breakpoints */
	--breakpoint-3xl: 120rem;
	--breakpoint-4xl: 160rem;

	/* Custom shadows */
	--shadow-glow: 0 0 20px rgba(139, 92, 246, 0.3);
}

Usage:

<div class="bg-brand-500 font-display shadow-glow">Custom themed element</div>

Color System

Using default colors:

<div class="bg-blue-500">Background</div>
<p class="text-red-600">Text</p>
<div class="border-green-400">Border</div>

Color scale:

  • 50: Lightest
  • 100-400: Light variations
  • 500: Base color
  • 600-800: Dark variations
  • 950: Darkest

Color opacity modifiers:

<div class="bg-black/75">75% opacity</div>

Responsive Design

Mobile-First Breakpoints

Tailwind uses a mobile-first approach. Base styles apply to all screen sizes, then use breakpoint prefixes to override at larger sizes:

Breakpoints:

  • sm: - 640px and up
  • md: - 768px and up
  • lg: - 1024px and up
  • xl: - 1280px and up
  • 2xl: - 1536px and up

Example:

<!-- Mobile: 1 column, Tablet: 2 columns, Desktop: 4 columns -->
<div class="grid grid-cols-1 gap-4 sm:grid-cols-2 lg:grid-cols-4">
	<div>Item 1</div>
	<div>Item 2</div>
	<div>Item 3</div>
	<div>Item 4</div>
</div>

<!-- Hide on mobile, show on desktop -->
<div class="hidden lg:block">Desktop only content</div>

<!-- Show on mobile, hide on desktop -->
<div class="block lg:hidden">Mobile only content</div>

<!-- Responsive text sizes -->
<h1 class="text-2xl md:text-4xl lg:text-6xl">Responsive heading</h1>

Custom Breakpoints

@theme {
	--breakpoint-3xl: 120rem;
	--breakpoint-tablet: 48rem;
}
<div class="tablet:grid-cols-2 3xl:grid-cols-6">Custom breakpoints</div>

Max-width Queries

<!-- Only apply styles below 768px -->
<div class="flex max-md:hidden">Hidden on mobile</div>

<!-- Between breakpoints -->
<div class="md:block lg:hidden">Only visible on tablets</div>

Container Queries

Style elements based on parent container width:

<div class="@container">
	<div class="@md:grid-cols-2 @lg:grid-cols-3">Responds to parent width</div>
</div>

Interactive States

Hover States

<button class="bg-blue-500 text-white hover:bg-blue-700">Hover me</button>

<a class="text-blue-600 hover:underline"> Hover link </a>

<div class="scale-100 transition-transform hover:scale-105">Scale on hover</div>

Focus States

<input class="border focus:border-blue-500 focus:ring-2 focus:ring-blue-200" />

<button
	class="bg-blue-500 focus:ring-4 focus:ring-blue-300 focus:outline-hidden"
>
	Accessible button
</button>

Active States

<button class="bg-blue-500 active:bg-blue-800">Click me</button>

Disabled States

<button
	class="bg-blue-500 disabled:cursor-not-allowed disabled:opacity-50"
	disabled
>
	Disabled button
</button>

<input class="disabled:bg-gray-100" disabled />

Form States

<input class="invalid:border-red-500 focus:invalid:ring-red-200" required />

<input
	class="placeholder:text-gray-400 placeholder:italic"
	placeholder="Search..."
/>

<input type="checkbox" class="checked:bg-blue-500" />

Group Hover (Parent State)

<div class="group hover:bg-gray-100">
	<p class="group-hover:text-blue-600">Text changes when parent is hovered</p>
	<img class="group-hover:opacity-50" src="..." />
</div>

Peer State (Sibling State)

<input type="checkbox" class="peer" id="terms" />
<label for="terms" class="peer-checked:text-blue-600"> I accept terms </label>

<input type="email" class="peer" required />
<p class="hidden text-red-600 peer-invalid:block">Invalid email</p>

Dark Mode

Setup Dark Mode

Media query approach (automatic):

<div class="bg-white text-gray-900 dark:bg-gray-900 dark:text-white">
	Auto switches based on system preference
</div>

Class-based approach (manual toggle):

// Add .dark class to <html> element
document.documentElement.classList.toggle("dark");

Dark Mode Utilities

<!-- Colors -->
<div class="bg-white dark:bg-slate-900">Background</div>
<p class="text-gray-900 dark:text-gray-100">Text</p>

<!-- Borders -->
<div class="border-gray-200 dark:border-gray-700">Border</div>

<!-- Complete example -->
<div
	class="rounded-lg border border-gray-200 bg-white p-6 dark:border-gray-700 dark:bg-gray-900"
>
	<h2 class="text-2xl font-bold text-gray-900 dark:text-white">
		Dark mode card
	</h2>
	<p class="text-gray-600 dark:text-gray-300">Content adapts to theme</p>
</div>

Dark Mode Toggle Implementation

// Store preference
function toggleDarkMode() {
	const isDark = document.documentElement.classList.toggle("dark");
	localStorage.setItem("theme", isDark ? "dark" : "light");
}

// Initialize on load
if (
	localStorage.theme === "dark" ||
	(!("theme" in localStorage) &&
		window.matchMedia("(prefers-color-scheme: dark)").matches)
) {
	document.documentElement.classList.add("dark");
}

Arbitrary Values

Use square brackets for one-off custom values:

Pixel values:

<div class="top-[117px]">Custom position</div>
<p class="text-[22px]">Custom font size</p>
<div class="w-[500px]">Custom width</div>

Colors:

<div class="bg-[#bada55]">Custom hex color</div>
<div class="text-[rgb(123,45,67)]">RGB color</div>
<div class="bg-[oklch(0.55_0.22_264)]">OKLCH color</div>

CSS variables:

<div class="bg-(--my-brand-color)">CSS variable</div>
<div class="text-(length:--my-font-size)">Type hint</div>

Complex values:

<div class="grid-cols-[1fr_500px_2fr]">Custom grid</div>
<div class="content-['>']">Custom content</div>
<div class="mask-type-luminance">Custom property</div>

	}
	to {
		transform: translateX(0);
	}
}
<div class="animate-slide-in">Custom animation</div>

Advanced Patterns

Custom Utilities

Create reusable utility classes:

@utility content-auto {
	content-visibility: auto;
}

@utility tab-* {
	tab-size: var(--tab-size-*);
}
<div class="content-auto">Custom utility</div>
<pre class="tab-4">Custom tab size</pre>

Custom Variants

@custom-variant theme-midnight (&:where([data-theme="midnight"] *));
@custom-variant aria-checked (&[aria-checked="true"]);
<div theme-midnight:bg-navy-900>Applies when data-theme="midnight"</div>

Layer Organization

@layer base {
	h1 {
		@apply text-4xl font-bold;
	}

	body {
		@apply bg-white text-gray-900;
	}
}

@layer components {
	.btn {
		@apply rounded bg-blue-500 px-4 py-2 text-white hover:bg-blue-700;
	}

	.card {
		@apply rounded-lg bg-white p-6 shadow-md;
	}
}

Apply Directive

Extract repeated utilities into CSS classes:

.btn-primary {
	@apply rounded bg-blue-500 px-4 py-2 font-bold text-white hover:bg-blue-700;
}

.input-field {
	@apply rounded-md border border-gray-300 px-3 py-2 focus:ring-2 focus:ring-blue-500 focus:outline-hidden;
}

	<div
		class="grid grid-cols-1 gap-6 sm:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4"
	>

		<div class="rounded-lg bg-white p-6 shadow-md">Item 4</div>
	</div>
</div>

Best Practices

1. Use Consistent Spacing Scale

<!-- Good: Use spacing scale -->
<div class="mb-6 p-4">
	<!-- Avoid: Arbitrary values unless necessary -->
	<div class="mb-[23px] p-[17px]"></div>
</div>

2. Leverage Design Tokens

<!-- Good: Use semantic color names -->
<button class="bg-blue-600 hover:bg-blue-700">
	<!-- Avoid: One-off colors -->
	<button class="bg-[#3B82F6] hover:bg-[#2563EB]"></button>
</button>

3. Mobile-First Responsive Design

<!-- Good: Mobile first, then scale up -->
<div class="text-base md:text-lg lg:text-xl">
	<!-- Avoid: Desktop first -->
	<div class="text-xl lg:text-base"></div>
</div>

4. Component Extraction

// React component with Tailwind
function Button({ children, variant = "primary" }) {
	const baseClasses = "font-semibold px-6 py-3 rounded-lg transition-colors";
	const variants = {
		primary: "bg-blue-600 hover:bg-blue-700 text-white",
		secondary: "bg-gray-200 hover:bg-gray-300 text-gray-900",
	};

	return (
		<button className={`${baseClasses} ${variants[variant]}`}>
			{children}
		</button>
	);
}

5. Use @apply for Repeated Patterns

/* Only use @apply for truly repeated patterns */
@layer components {
	.card {
		@apply rounded-lg bg-white p-6 shadow-md transition-shadow hover:shadow-lg;
	}
}

6. Accessibility First

<button class="focus:ring-4 focus:ring-blue-300 focus:outline-hidden">
	Accessible button
</button>

<a class="text-blue-600 hover:underline focus:outline-2 focus:outline-offset-2">
	Accessible link
</a>

7. Performance Optimization

  • Use PurgeCSS in production (automatic with modern setup)
  • Avoid dynamic class names: class={text-${color}-500} won't work
  • Use safelist for dynamic classes if needed

8. Dark Mode Consistency

<!-- Ensure all elements have dark mode variants -->
<div
	class="border border-gray-200 bg-white text-gray-900 dark:border-gray-700 dark:bg-gray-900 dark:text-white"
>
	Complete dark mode support
</div>

Common Patterns

Centering Content

<!-- Horizontal center -->
<div class="flex justify-center">Content</div>
<div class="mx-auto w-fit">Content</div>

<!-- Vertical center -->
<div class="flex h-screen items-center">Content</div>

<!-- Center both axes -->
<div class="flex h-screen items-center justify-center">Centered content</div>

Full-Width Container with Max Width

<div class="container mx-auto max-w-7xl px-4">

Troubleshooting

Classes Not Working

  1. Check content configuration:
// tailwind.config.js
content: [
	"./src/**/*.{js,jsx,ts,tsx}",
	// Add all file paths where you use Tailwind
];
  1. Dynamic classes won't work:
// ❌ Won't work
const color = 'blue'
<div className={`text-${color}-500`} />

// ✅ Works
<div className={color === 'blue' ? 'text-blue-500' : 'text-red-500'} />
  1. Specificity issues:
/* Use !important sparingly */
<div class="text-red-500!">Overrides other styles</div>

Build Issues

# Clear cache and rebuild
rm -rf .next node_modules/.cache
npm run dev

IntelliSense Not Working

Install official extension:

  • VS Code: "Tailwind CSS IntelliSense"
  • Configure in .vscode/settings.json:
{
	"tailwindCSS.experimental.classRegex": [
		["cva\\(([^)]*)\\)", "[\"'`]([^\"'`]*).*?[\"'`]"]
	]
}
