Understanding Responsive Breakpoints

What are Breakpoints?

Breakpoints are specific screen widths where your website's layout changes to provide the best user experience. They're defined using CSS media queries.

Mobile-First vs Desktop-First

  • Mobile-First (min-width): Start with mobile styles, then add styles for larger screens. Recommended for modern web development.
  • Desktop-First (max-width): Start with desktop styles, then override for smaller screens. Useful for legacy projects.

Common Breakpoint Ranges

  • Mobile: 320px - 767px (smartphones)
  • Tablet: 768px - 1023px (tablets and small laptops)
  • Desktop: 1024px+ (desktops and large screens)
  • Large Desktop: 1440px+ (wide monitors)

Best Practices

  • Use mobile-first approach for better performance
  • Keep breakpoints consistent across your project
  • Test on real devices, not just browser DevTools
  • Consider content, not just device sizes
  • Use em or rem for breakpoints to respect user font size preferences
