Hints are always available. Wrong turns never cost XP.

1
Build subtle shadows
Build this first target: .card with background-color: #ffffff. Keep the selector relationships intact and inspect the preview.
Hint & worked example
A restrained shadow can separate surfaces; it is not a substitute for content hierarchy.
The requested selectors and declarations exist outside comments.
```
.card { background-color: #ffffff; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.
2
Extend the subtle shadows example
Extend your file to include: .card with background-color: #ffffff; .card with box-shadow: 0 2px 8px #00000014. Keep the selector relationships intact and inspect the preview.
Hint & worked example
A restrained shadow can separate surfaces; it is not a substitute for content hierarchy.
The requested selectors and declarations exist outside comments.
```
.card { background-color: #ffffff; }
.card { box-shadow: 0 2px 8px #00000014; }
```
Common mistake to avoid: Hiding all overflow always makes content accessible.
3
Verify the complete subtle shadows pattern
Finish the pattern with: .card with background-color: #ffffff; .card with box-shadow: 0 2px 8px #00000014; .card with border: 1px solid #d9e2dd. Keep the selector relationships intact and inspect the preview.

Understand the pattern

A restrained shadow can separate surfaces; it is not a substitute for content hierarchy.

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 { background-color: #ffffff; }
.card { box-shadow: 0 2px 8px #00000014; }
.card { border: 1px solid #d9e2dd; }

A restrained shadow can separate surfaces; it is not a substitute for content hierarchy.

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 subtle shadows?If the page fits one desktop viewport, no narrower viewport needs checking.Hiding all overflow always makes content accessible.A restrained shadow can separate surfaces; it is not a substitute for content hierarchy.

Apply it elsewhere

You reuse subtle shadows 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.
