Introduction to Tailwind CSS

Key Characteristics

• Utility-First: Compose designs directly in your markup with utility classes
• Responsive: Built-in responsive design system
• Component-Friendly: Extract reusable components from repeated utility patterns
• Customizable: Tailor the framework to your design system
• Modern: Built with modern CSS features and best practices

Feature	Traditional CSS Frameworks	CSS Methodologies	Tailwind CSS
Approach	Pre-designed components	Naming conventions	Utility classes
Learning Curve	Learn component names and modifiers	Learn naming conventions and rules	Learn utility class names
Customization	Override pre-existing styles	Write custom CSS	Configure theme values
File Size	Large, includes unused styles	Depends on implementation	Small, purges unused styles
Design Freedom	Limited by framework design	High, but requires custom CSS	High, with utility composition
Examples	Bootstrap, Bulma, Foundation	BEM, SMACSS, OOCSS	Tailwind CSS

<!-- Bootstrap Button -->
<button class="btn btn-primary">
  Submit
</button>

<!-- Tailwind Button -->
<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Submit
</button>

Ideal Use Cases

• Custom UI designs: When you need to implement unique designs that don't fit neatly into existing frameworks
• Design system implementation: When translating a design system into code with consistent tokens
• Rapid prototyping: When you need to quickly build and iterate on UI concepts
• Component-based architectures: When working with React, Vue, or other component frameworks
• Design-to-code workflows: When implementing designs from Figma, Sketch, or other design tools

Considerations

• Learning curve: Developers need to learn Tailwind's utility classes
• HTML verbosity: Markup can become lengthy with multiple utility classes
• Team adoption: Requires buy-in from the entire development team
• Legacy projects: May be challenging to integrate with existing CSS architectures

1. Installation

Install Tailwind CSS via npm:

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

2. Configuration

Configure your template paths in tailwind.config.js:

module.exports = {
  content: ["./src/**/*.{html,js}"],
  theme: {
    extend: {},
  },
  plugins: [],
}

3. Add Tailwind Directives

Add the Tailwind directives to your CSS:

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

4. Start Building

Begin using Tailwind's utility classes in your HTML:

<div class="p-6 max-w-sm mx-auto bg-white rounded-xl shadow-lg flex items-center space-x-4">
  <div class="shrink-0">
    <img class="h-12 w-12" src="/img/logo.svg" alt="Logo">
  </div>
  <div>
    <div class="text-xl font-medium text-black">ChitChat</div>
    <p class="text-slate-500">You have a new message!</p>
  </div>
</div>

Understanding the Classes

Class	Purpose
p-6	Padding on all sides (1.5rem)
max-w-sm	Maximum width (24rem)
mx-auto	Horizontal margin auto (centers the element)
bg-white	Background color white
rounded-xl	Border radius (0.75rem)
shadow-lg	Large box shadow
flex items-center space-x-4	Flexbox layout with centered items and horizontal spacing
