Wall of Love Testimonial Grid (CSS Columns)

The high-density "wall of love" every indie SaaS ships once it has more praise than a carousel can hold — variable-height quote cards packed into a true masonry rhythm by column-count, with zero JavaScript and zero layout shift. The filter chips are pure CSS too: radio inputs plus a :has() rule on the root, so switching between Product, Support and Migration quotes never touches the main thread.

Demo: Wall of Love Testimonial Grid (CSS Columns)
Source: https://codefronts.com/components/css-testimonials-reviews/wall-of-love-testimonial-grid-css-columns/

The high-density "wall of love" every indie SaaS ships once it has more praise than a carousel can hold — variable-height quote cards packed into a true masonry rhythm by column-count, with zero JavaScript and zero layout shift. The filter chips are pure CSS too: radio inputs plus a :has() rule on the root, so switching between Product, Support and Migration quotes never touches the main thread.

How this works

CSS multi-column is the oldest masonry trick and still the cheapest. Three declarations do the whole layout:

.wall {
  column-count: 3;
  column-gap: 18px;
}
.card {
  break-inside: avoid;     /* never split a quote across columns */
  margin-bottom: 18px;     /* columns have no row-gap — margin is the gap */
}

Because the browser flows cards top-to-bottom then left-to-right, cards of any height tessellate with no gaps and no measuring pass. Add columns: 300px instead of a fixed count and the wall becomes responsive with a single value — the browser picks the column count from the available width.

Filtering is :has() reading a hidden radio group from the root element:

.tr-01:has(#tr-01-support:checked)
  .tr-01__card:not([data-src='support']) { display: none; }

The parent selector lets one checked input restyle any descendant, so a filter that used to need a click handler and a class toggle is now four lines of CSS. Cards carry data-src as their taxonomy, which keeps the markup semantic and the rule readable.

Every quote is a real <figure> → <blockquote> + <figcaption>, and each star row is one role="img" with an aria-label carrying the score — a screen reader hears "Rated 5 out of 5", not ten stray path elements.

Make it yours

  • Swap column-count:3 for columns:300px to let the browser choose the count — one line, fully fluid, no media queries.
  • Prefer real grid masonry? grid-template-rows: masonry ships behind a flag in Firefox and as item-pack in Chrome's proposal; keep this as the shipping baseline and progressively enhance inside @supports.
  • Highlight a marquee quote by giving one card column-span: all — it breaks the flow into a full-width band, exactly like a pull quote in print.
  • Re-theme with a single token: every surface, border and chip color derives from --tr-01-acc through color-mix(), so one oklch hue change restyles the entire wall.

Gotchas — read before shipping

  • Without break-inside: avoid a card will be sliced across two columns mid-sentence. Add -webkit-column-break-inside: avoid for older Safari builds.
  • Multi-column has no row-gap. The vertical rhythm comes from margin-bottom on the card — set column-gap and margin to the same value or the grid looks lopsided.
  • Reading order is column-by-column, not visual left-to-right across the page. For a wall of independent quotes that is fine; never use columns for sequential content like steps.
  • display:none filtering removes cards from the accessibility tree — that is what you want. Toggling visibility:hidden instead leaves them announced but invisible.
  • Cards with transforms inside a multicol container can flicker during repaint in older WebKit. Animate translate and opacity only, and keep will-change off the card itself.

Browser support

ChromeSafariFirefoxEdge
114+17.5+121+114+

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

:has() is the floor (Chrome 105, Safari 15.4, Firefox 121). CSS multi-column is universal since IE10. Without :has() the filter chips simply do nothing and the full wall stays visible — a genuinely harmless degradation.
