Responsive Design

Build websites that work beautifully on any device — from phones to ultrawide monitors.

Learning Objectives​

  • Implement mobile-first responsive design strategies
  • Use media queries, fluid grids, and flexible images
  • Test across multiple screen resolutions and devices
  • Understand viewport units and modern CSS sizing

Key Topics​

Mobile-First Approach​

Start with the smallest screen and progressively enhance. This ensures your core content is always accessible.

Media Queries​

Use breakpoints strategically — not for specific devices, but for when your layout breaks. Let the content dictate the breakpoints.

Modern CSS Tools​

Leverage clamp(), container queries, and CSS Grid's auto-fit/auto-fill for layouts that adapt naturally without excessive media queries.

Exercise​

Take an existing desktop-only layout and refactor it to be fully responsive. Test on at least three different viewport widths.
