1
Build visual polish checkpoint
Build this first target: main with color: #182b2a, background-color: #ffffff, line-height: 1.6. Keep the selector relationships intact and inspect the preview.
Hint & worked example
Readable typography, one action hierarchy, and a keyboard focus treatment are useful polish before decorative effects.
The requested selectors and declarations exist outside comments.
```
main { color: #182b2a; background-color: #ffffff; line-height: 1.6; }
```
Common mistake to avoid: If the page fits one desktop viewport, no narrower viewport needs checking.
2
Extend the visual polish checkpoint example
Extend your file to include: main with color: #182b2a, background-color: #ffffff, line-height: 1.6; button with padding: 0.75rem 1rem, color: #ffffff, background-color: #164e45. Keep the selector relationships intact and inspect the preview.

main { color: #182b2a; background-color: #ffffff; line-height: 1.6; }
button { padding: 0.75rem 1rem; color: #ffffff; background-color: #164e45; }
```
Common mistake to avoid: Hiding all overflow always makes content accessible.
3
Verify the complete visual polish checkpoint pattern
Finish the pattern with: main with color: #182b2a, background-color: #ffffff, line-height: 1.6; button with padding: 0.75rem 1rem, color: #ffffff, background-color: #164e45; button:focus-visible with outline: 3px solid #164e45, outline-offset: 3px. Keep the selector relationships intact and inspect the preview.

Understand the pattern

Readable typography, one action hierarchy, and a keyboard focus treatment are useful polish before decorative effects.

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

main { color: #182b2a; background-color: #ffffff; line-height: 1.6; }
button { padding: 0.75rem 1rem; color: #ffffff; background-color: #164e45; }
button:focus-visible { outline: 3px solid #164e45; outline-offset: 3px; }

Readable typography, one action hierarchy, and a keyboard focus treatment are useful polish before decorative effects.

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 visual polish checkpoint?Readable typography, one action hierarchy, and a keyboard focus treatment are useful polish before decorative effects.If the page fits one desktop viewport, no narrower viewport needs checking.Hiding all overflow always makes content accessible.

Apply it elsewhere

You reuse visual polish checkpoint 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.
