1
Build spacing with padding
Build this first target: .notice with padding: 1rem. Keep the selector relationships intact and inspect the preview.
Hint & worked example
Padding creates space inside the border; it does not separate the element from its neighbors.
The requested selectors and declarations exist outside comments.
```
.notice { padding: 1rem; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.
2
Extend the spacing with padding example
Extend your file to include: .notice with padding: 1rem; .notice with border: 1px solid #658b84. Keep the selector relationships intact and inspect the preview.
Hint & worked example
Padding creates space inside the border; it does not separate the element from its neighbors.
The requested selectors and declarations exist outside comments.
```
.notice { padding: 1rem; }
.notice { border: 1px solid #658b84; }
```
Common mistake to avoid: Hiding all overflow always makes content accessible.
3
Verify the complete spacing with padding pattern
Finish the pattern with: .notice with padding: 1rem; .notice with border: 1px solid #658b84; .notice with box-sizing: border-box. Keep the selector relationships intact and inspect the preview.
Hint & worked example
Padding creates space inside the border; it does not separate the element from its neighbors.

```
.notice { padding: 1rem; }
.notice { border: 1px solid #658b84; }
.notice { box-sizing: border-box; }
```

Understand the pattern

Padding creates space inside the border; it does not separate the element from its neighbors.

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

.notice { padding: 1rem; }
.notice { border: 1px solid #658b84; }
.notice { box-sizing: border-box; }

Padding creates space inside the border; it does not separate the element from its neighbors.

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 spacing with padding?Padding creates space inside the border; it does not separate the element from its neighbors.If the page fits one desktop viewport, no narrower viewport needs checking.Hiding all overflow always makes content accessible.

Apply it elsewhere

You reuse spacing with padding 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.
