Responsive design made easy

Kevin Powell walks through why layouts that look fine on desktop fall apart on smaller screens, and the fixes are the exact culprits behind most mobile breaks: fixed pixel widths, missing flexible units, and clumsy media queries. He builds it visually so you see the break and the fix side by side rather than just reading rules. It is a practical starting point for anyone whose landing page shrinks badly on a phone.

• Swap hardcoded px widths for relative units and max-width so content flexes instead of overflowing on narrow screens.
• Use min(), max(), and clamp() to size things fluidly and lean less on brittle breakpoints.
• Build mobile first, then layer on desktop enhancements, rather than shrinking a desktop layout down.
