Responsive CSS Summary

Responsive Summary

Responsive CSS combines the viewport meta tag, mobile-first media queries, fluid units, clamp(), auto-fit grids, container queries, and print styles to create layouts that work on any device.

Example

/* Core responsive toolkit */
:root { --max-w: 1140px; --gap: clamp(1rem, 3vw, 2rem); }
.container { width: min(100% - 2rem, var(--max-w)); margin-inline: auto; }
.grid { display: grid; grid-template-columns: repeat(auto-fit, minmax(min(260px,100%),1fr)); gap: var(--gap); }

Pro Tip

Start every project with the viewport meta tag and a fluid container — everything else builds on top.
