Container Queries

ELI5 — The Vibe Check

Container Queries are the CSS feature we begged for years. Instead of 'how wide is the screen?' they ask 'how wide is my parent container?' Finally, a card component can adapt to its container whether it's in a sidebar or full-width. Components that truly own their responsiveness.

Real Talk

Container Queries are a CSS feature that allows elements to be styled based on the size of their containing element rather than the viewport. Using @container rules and container-type declarations, components can adapt their layout independently of the overall page dimensions.

Show Me The Code

.card-container { container-type: inline-size; }
@container (min-width: 400px) {
  .card { display: grid; grid-template-columns: 1fr 1fr; }
}
