What is Responsive Web Design?

Responsive web design is an approach that makes web pages render well on a variety of devices and window or screen sizes. It uses flexible layouts, images, and CSS media queries to adapt to different screen sizes.

Key Components of Responsive Design

1. Flexible Grid Systems

Use CSS Grid and Flexbox to create layouts that adapt to different screen sizes. These modern CSS features provide powerful tools for creating responsive layouts.

2. Flexible Images and Media

Implement responsive images using the srcset attribute and CSS techniques to ensure images look great on all devices.

3. CSS Media Queries

Use media queries to apply different styles for different screen sizes, orientations, and device capabilities.

4. Typography Scaling

Implement fluid typography that scales appropriately across different screen sizes using techniques like clamp() and viewport units.
