Responsive Web Design (RWD) is a crucial approach to create websites that adapt to any device and screen size. Here's a concise guide:

Key Principles ✅

  1. Fluid Grids
    Use relative units (e.g., %, fr) for layout sizing.

  2. Flexible Images
    Ensure images scale with their containers: 

    img { max-width: 100%; height: auto; }

  3. Media Queries 📱
    Apply conditional styling for different breakpoints: 

    @media (max-width: 768px) { /* mobile-specific rules */ }
    media_queries

Implementation Tools 🛠️

  • CSS Flexbox for dynamic layout alignment
  • CSS Grid for complex responsive structures
  • CSS Variables (--) for scalable theme management
  • Meta Viewport Tag in HTML: 
    <meta name="viewport" content="width=device-width, initial-scale=1">

Best Practices 📌

  • Test across devices using tools like BrowserStack
  • Prioritize content hierarchy and readability
  • Use a mobile-friendly font size (e.g., 16px as base)
