How this works

Give six columns different numbers of links and their internal rows drift: column 3's "See all" link sits 40px above column 5's. The usual fix is a fixed min-height, which breaks the moment the copy changes. Subgrid makes the children share the parent's rows instead:

.cols{ display:grid; grid-template-columns:repeat(6,1fr);
       grid-template-rows: auto 1fr auto }   /* heading · links · footer link */
.col { display:grid; grid-row: span 3; grid-template-rows: subgrid }

Each column now inherits the parent's three row tracks, so all headings align, all lists start together, and all trailing links sit on one line — with zero magic numbers and no JS measurement.

The brand cell spans two columns with grid-column: span 2, and the whole arrangement collapses at narrow widths by swapping the explicit six-track definition for repeat(auto-fit,minmax(10rem,1fr)) inside a container query — the columns get narrower and then fewer, in that order.

Two details that keep a 60-link footer usable: every column is a <nav aria-labelledby> so a screen-reader user can jump between groups, and the gap does all vertical rhythm work (no margins anywhere), so removing a link never leaves a hole.

Where subgrid is unavailable the columns simply lay out as normal grid children — headings still align because they are the first child of each column; only the trailing links lose their shared baseline. That is the correct kind of degradation: nothing breaks, one refinement is missing.

Make it yours

  • Column count: change repeat(6,1fr). The subgrid rule is count-independent.
  • More shared rows: add tracks to the parent (auto auto 1fr auto) and bump the span to match — a per-column badge or count line then aligns too.
  • Region/locale row: add a full-width area under the columns with grid-column:1/-1.
  • Compact mode for app shells: the container query threshold is a single value — set it to the width where six columns stop being readable in your type scale.

Gotchas — read before shipping

  • grid-template-rows: subgrid only works if the child spans multiple parent rows — grid-row: span 3 is required, and forgetting it silently does nothing.
  • Subgrid inherits tracks, not gaps by default — set gap on the child to inherit or re-declare it if you need matching internal spacing.
  • A 60-link footer without grouped navs is a screen-reader maze. <nav aria-labelledby> per column is not optional at this size.
  • Don't reduce footer link font-size to make six columns fit; reduce the column count instead. 14px is the floor.
  • Avoid nesting a second grid inside a column for 'sub-links' — indent them in the same list with a modifier class so the subgrid alignment survives.

Browser support

ChromeSafariFirefoxEdge

Subgrid is now supported in all three engines (Chrome 117, late 2023). Older browsers ignore the subgrid value and fall back to normal grid children — headings still align, trailing links do not.
