Container queries let a component respond to its parent's width instead of the viewport — perfect for reusable cards and widgets.

Container nameBreakpoint 400px

CSS

/* 1. Mark the parent as a container */
.card-wrap {
  container-type: inline-size;
  container-name: card;
}

/* 2. Style children based on the CONTAINER's width (not the viewport) */
@container card (min-width: 400px) {
  .card {
    display: grid;
    grid-template-columns: 1fr 1fr;
    gap: 1rem;
  }
}
