Hints are always available. Wrong turns never cost XP.

1
Build desktop media query
Build this first target: .layout with display: grid, grid-template-columns: 1fr. Keep the selector relationships intact and inspect the preview.
Hint & worked example
A min-width query layers a wider arrangement on top of a simple mobile-first layout.
The requested selectors and declarations exist outside comments.
```
.layout { display: grid; grid-template-columns: 1fr; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.
2
Extend the desktop media query example
Extend your file to include: .layout with display: grid, grid-template-columns: 1fr; @media(min-width:48rem) — .layout with grid-template-columns: repeat(2,minmax(0,1fr)). Keep the selector relationships intact and inspect the preview.

```
.layout { display: grid; grid-template-columns: 1fr; }
@media (min-width: 48rem) { .layout { grid-template-columns: repeat(2, minmax(0, 1fr)); } }
```
Common mistake to avoid: Hiding all overflow always makes content accessible.
3
Verify the complete desktop media query pattern
Finish the pattern with: .layout with display: grid, grid-template-columns: 1fr; @media(min-width:48rem) — .layout with grid-template-columns: repeat(2,minmax(0,1fr)); .layout with gap: 1.25rem. Keep the selector relationships intact and inspect the preview.

Understand the pattern

A min-width query layers a wider arrangement on top of a simple mobile-first layout.

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; grid-template-columns: 1fr; }
@media (min-width: 48rem) { .layout { grid-template-columns: repeat(2, minmax(0, 1fr)); } }
.layout { gap: 1.25rem; }

A min-width query layers a wider arrangement on top of a simple mobile-first layout.

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 desktop media query?If the page fits one desktop viewport, no narrower viewport needs checking.Hiding all overflow always makes content accessible.A min-width query layers a wider arrangement on top of a simple mobile-first layout.

Apply it elsewhere

You reuse desktop media query 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.
