Development Approach

Tailwinds Utility-First Philosophy

Tailwind CSS embraces a utility-first approach:

<div class="flex items-center justify-between p-4 bg-blue-500 text-white rounded-lg shadow-md hover:bg-blue-600">
  <h2 class="text-xl font-bold">Welcome</h2>
  <button class="px-4 py-2 bg-white text-blue-500 rounded">Click Me</button>
</div>

Bootstraps Component-Based Approach

Bootstrap provides pre-built components:

<div class="card">
  <div class="card-body">
    <h2 class="card-title">Welcome</h2>
    <button class="btn btn-primary">Click Me</button>
  </div>
</div>

Customization Options

Tailwind CSS

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        primary: '#1a2b3c',
        secondary: '#4d5e6f'
      },
      spacing: {
        '128': '32rem'
      }
    }
  }
}

Bootstrap
