Perfect for Typography: Create fluid text that scales smoothly between breakpoints. Great for headings, body text, and buttons.
h1 { font-size: clamp(1.5rem, 4vw, 3rem); }Spacing & Layout: Use clamp() for responsive padding, margins, and gaps that adapt to screen size automatically.
section { padding: clamp(1rem, 5vw, 4rem); }No Media Queries Needed: One CSS declaration replaces multiple media query breakpoints, making your code cleaner.
Instead of 3 @media rules, use one clamp()Accessible by Default: Using rem units respects user font size preferences. Always test with different browser zoom levels.
Zoom to 200% to verify readabilityStart Conservative: Begin with subtle scaling (16px → 18px) then increase range as needed. Too much scaling can hurt readability.
Body text: 16px → 18px is often enough
