Hints are always available. Wrong turns never cost XP.

1
Build card rhythm
Build this first target: .card with padding: 1.25rem. Keep the selector relationships intact and inspect the preview.
Hint & worked example
Consistent internal spacing makes repeated content easier to compare than arbitrary per-card offsets.
The requested selectors and declarations exist outside comments.
```
.card { padding: 1.25rem; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.
2
Extend the card rhythm example
Extend your file to include: .card with padding: 1.25rem; .card with display: grid, gap: 0.75rem. Keep the selector relationships intact and inspect the preview.
Hint & worked example
Consistent internal spacing makes repeated content easier to compare than arbitrary per-card offsets.
The requested selectors and declarations exist outside comments.
```
.card { padding: 1.25rem; }
.card { display: grid; gap: 0.75rem; }
```
Common mistake to avoid: Hiding all overflow always makes content accessible.
3
Verify the complete card rhythm pattern
Finish the pattern with: .card with padding: 1.25rem; .card with display: grid, gap: 0.75rem; .card h2,.card p with margin: 0. Keep the selector relationships intact and inspect the preview.
Hint & worked example
Consistent internal spacing makes repeated content easier to compare than arbitrary per-card offsets.

```
.card { padding: 1.25rem; }
.card { display: grid; gap: 0.75rem; }
.card h2, .card p { margin: 0; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.

Understand the pattern

Consistent internal spacing makes repeated content easier to compare than arbitrary per-card offsets.

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

.card { padding: 1.25rem; }
.card { display: grid; gap: 0.75rem; }
.card h2, .card p { margin: 0; }

Consistent internal spacing makes repeated content easier to compare than arbitrary per-card offsets.

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 card rhythm?If the page fits one desktop viewport, no narrower viewport needs checking.Hiding all overflow always makes content accessible.Consistent internal spacing makes repeated content easier to compare than arbitrary per-card offsets.

Apply it elsewhere

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

Keep the momentum.

Complete the lab, then explain and apply the pattern.
