Responsive web design creates websites that automatically adapt to different screen sizes and devices — from mobile phones to desktop monitors. Using CSS techniques like media queries, flexible grids, and fluid images, a single website provides optimal viewing across all devices. With 70%+ of Indian internet traffic coming from mobile, responsive design is not optional — it's essential.
Key Points
- Single codebase adapts to all screen sizes
- Mobile-first approach: design for mobile, then enhance for larger screens
- CSS techniques: media queries, flexbox, CSS grid, fluid typography
- Google uses mobile-friendliness as a ranking factor
Frequently Asked Questions
Responsive design is almost always better. It's easier to maintain (one codebase), better for SEO (Google prefers responsive), and more cost-effective. Separate mobile sites (m.example.com) are a legacy approach that creates maintenance headaches. The only exception might be when mobile and desktop experiences are fundamentally different (rare).
Start with a mobile viewport meta tag, then use CSS media queries to adjust layouts at different breakpoints (typically 768px for tablet, 1024px for desktop). Replace fixed-width layouts with flexbox or CSS grid. Ensure images are responsive (max-width: 100%). Test on real devices, not just browser DevTools, as performance differs.
