Hints are always available. Wrong turns never cost XP.

1
Build flexible rows
Build this first target: .layout with display: flex. Keep the selector relationships intact and inspect the preview.
Hint & worked example
A flex container lays out its direct children along a main axis; gap separates items.
The requested selectors and declarations exist outside comments.
```
.layout { display: flex; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.
2
Extend the flexible rows example
Extend your file to include: .layout with display: flex; .layout with gap: 1rem. Keep the selector relationships intact and inspect the preview.
Hint & worked example
A flex container lays out its direct children along a main axis; gap separates items.
The requested selectors and declarations exist outside comments.
```
.layout { display: flex; }
.layout { gap: 1rem; }
```
Common mistake to avoid: Hiding all overflow always makes content accessible.
3
Verify the complete flexible rows pattern
Finish the pattern with: .layout with display: flex; .layout with gap: 1rem; .layout with align-items: center. Keep the selector relationships intact and inspect the preview.

.layout { display: flex; }

Understand the pattern

A flex container lays out its direct children along a main axis; gap separates items.

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: flex; }
.layout { gap: 1rem; }
.layout { align-items: center; }

A flex container lays out its direct children along a main axis; gap separates items.

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 flexible rows?A flex container lays out its direct children along a main axis; gap separates items.If the page fits one desktop viewport, no narrower viewport needs checking.Hiding all overflow always makes content accessible.

Apply it elsewhere

You reuse flexible rows 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.
