Viewport Meta Tag
The viewport meta tag tells browsers how to handle device width and scaling. It’s a small line that makes a huge difference. Without it, your responsive design won’t work properly on mobile devices.
Breakpoints Strategy
You don’t need dozens of breakpoints. Most projects work fine with three or four key breakpoints. The trick is choosing breakpoints based on your content, not just device sizes.
Relative Units Matter
Pixels are fixed. That’s why responsive design relies on percentages, ems, and rems. Learning when to use each unit is crucial for layouts that actually adapt smoothly.
Touch-Friendly Design
Mobile devices use touch, not mouse cursors. That means buttons need to be bigger, spacing needs adjustment, and hover states don’t work the same way. Plan for touch from the start.
