Yo folks, I’m wiring up a checkout form that sits inside responsive “card” tiles, and the annoying failure mode is when a single validation message gets long and the whole grid jumps or the card overflows on mobile.

```css
.cards {
  display: grid;
  gap: 12px;
  grid-template-columns: repeat(auto-fit, minmax(260px, 1fr));
  align-items: start;
}

.card {
  display: flex;
  flex-direction: column;
  min-width: 0;
  overflow: clip;
}

.field {
  display: grid;
  grid-template-rows: auto auto;
}

.error {
  min-height: 1.25em;
  overflow-wrap: anywhere;
}

```

Neat little combo: grid handles the responsive columns, flex keeps each card stacked, and the reserved `.error` height stops layout thrash when validation toggles while still letting long messages wrap instead of blowing out the card.

`min-width: 0` on `.card` is doing a ton of work here. Without it, one ugly unbroken token in an error string (order IDs, pasted URLs, whatever) will force min-content sizing and you get the “why is my grid wider than the viewport” nonsense on mobile.

One thing that’s bitten me in this exact pattern: make sure the _thing actually holding the text_ can shrink too. If `.error` contains a `<p>`/`span` that’s still acting like it has a min-content floor, `overflow-wrap: anywhere` won’t save you and you’ll still get one rogue card blowing out while the rest behave. I’ve had to put `min-width: 0` on the inner wrapper more than once when everything “looked right” in CSS but didn’t in reality.

And yeah, I’d drop the kirupa link — the snippet + the failure mode explanation is the value.
