Hints are always available. Wrong turns never cost XP.

1
Build repeatable card grid
Build this first target: .layout with display: grid. Keep the selector relationships intact and inspect the preview.
Hint & worked example
auto-fit repeats as many tracks as fit; the minimum controls when cards wrap.
The requested selectors and declarations exist outside comments.
```
.layout { display: grid; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.
2
Extend the repeatable card grid example
Extend your file to include: .layout with display: grid; .layout with grid-template-columns: repeat(auto-fit,minmax(12rem,1fr)). Keep the selector relationships intact and inspect the preview.
Hint & worked example
auto-fit repeats as many tracks as fit; the minimum controls when cards wrap.
The requested selectors and declarations exist outside comments.
```
.layout { display: grid; }
.layout { grid-template-columns: repeat(auto-fit, minmax(12rem, 1fr)); }
```
Common mistake to avoid: Hiding all overflow always makes content accessible.
3
Verify the complete repeatable card grid pattern
Finish the pattern with: .layout with display: grid; .layout with grid-template-columns: repeat(auto-fit,minmax(12rem,1fr)); .layout with gap: 1rem. Keep the selector relationships intact and inspect the preview.

Understand the pattern

auto-fit repeats as many tracks as fit; the minimum controls when cards wrap.

Misconceptions to reject

If the page fits one desktop viewport, no narrower viewport needs checking.
Hiding all overflow always makes content accessible.

The preview is a sanitized subset, not a full browser compatibility test.

Worked example and expected result

.layout { display: grid; }
.layout { grid-template-columns: repeat(auto-fit, minmax(12rem, 1fr)); }
.layout { gap: 1rem; }

auto-fit repeats as many tracks as fit; the minimum controls when cards wrap.

Try a variation

Adapt the final example to a different project name while retaining its structure and relationships. A different context still needs a real browser and accessibility check.

Explain it

Which statement correctly explains repeatable card grid?auto-fit repeats as many tracks as fit; the minimum controls when cards wrap.If the page fits one desktop viewport, no narrower viewport needs checking.Hiding all overflow always makes content accessible.

Apply it elsewhere

You reuse repeatable card grid in a different project. What must still be verified?Nothing; passing a single exercise guarantees every future use.Only whether the source code has the same number of lines.The resulting layout, focus behavior, and readability at the target viewport sizes.

Keep the momentum.

Complete the lab, then explain and apply the pattern.
