SaaS Product Mega Footer with Resource Grid

The big-surface SaaS footer: a promoted resource rail of three real content cards sitting above six link columns, so the last screen of the page does conversion work instead of just listing URLs. Named grid areas keep the whole arrangement readable, and the mobile order is declared, not accidental.

How this works

A mega footer has three jobs stacked on top of each other, so the layout is declared as named areas rather than a pile of nested divs:

.mega{
  display:grid;
  grid-template-areas:
    'promo promo promo'
    'links links links'
    'legal legal legal';
}
@media (min-width:60rem){
  .mega{ grid-template-areas: 'promo links links' 'legal legal legal' }
}

Areas are worth the extra lines here because the reading order on mobile (resources first, then links, then legal) is different from the desktop arrangement, and areas let you say that once in the stylesheet instead of reordering the DOM — the DOM stays in the order a screen reader should hear it.

The resource cards use aspect-ratio on the thumbnail so images never cause layout shift while they load, and the hover treatment is a gradient hairline drawn with a masked pseudo-element:

.card::before{
  content:'';position:absolute;inset:0;border-radius:inherit;padding:1px;
  background:linear-gradient(140deg, var(--acc), transparent 60%);
  -webkit-mask: linear-gradient(#000 0 0) content-box, linear-gradient(#000 0 0);
  -webkit-mask-composite: xor; mask-composite: exclude;
}

That is the only reliable way to get a gradient border with a rounded corner that follows border-radius — border-image does not respect radii.

Finally the whole card is one link: the anchor wraps nothing, it sits absolutely inside the card as a stretched pseudo-element (a::after{position:absolute;inset:0}). One tab stop, one announcement, the full card clickable, and any real text inside stays selectable.

Make it yours

  • Number of resource cards: the rail is repeat(auto-fit,minmax(min(15rem,100%),1fr)) — add a fourth card and it fits itself in.
  • Swap the promo rail for a product screenshot or a demo video by giving the promo area a single full-bleed figure — the areas map does not change.
  • Six columns to four: change the link grid's minmax() minimum; the legal bar is a separate area so it is unaffected.
  • Brand the cards per category with --card-acc set per card and every accent (border, pill, arrow) reading from it.

Gotchas — read before shipping

  • Card-wide click targets built by wrapping a whole card in <a> make the link's accessible name the entire card text. Use the stretched-pseudo-element pattern with a short, meaningful link label instead.
  • Every grid-template-areas row string must have the same number of cells or the whole declaration is invalid and silently dropped — a common cause of a mega footer that looks unstyled.
  • Thumbnails without aspect-ratio or width/height attributes are the biggest CLS source in a footer, because footer images load last.
  • A footer with 40+ links needs the <nav aria-labelledby> grouping from demo 02 far more than the small ones do — without it the landmarks list is useless.
  • Do not put the only path to critical pages (pricing, security, status) exclusively in a mega footer; footers are skipped by most keyboard and mobile users.

Floor set by :has(), oklch(), text-wrap as this demo is written. The core technique itself goes back further — Chrome 105+.

grid-template-areas, aspect-ratio and mask-composite are broadly supported. :has() (used to tint a card group on hover) needs Chrome 105 / Safari 15.4 / Firefox 121 and degrades to no tint.
