Common Mistakes

Using % instead of px for fixed pixel width.

Forgetting to add any unit after the number.

The px unit means pixels, which sets the width to exactly 100 pixels.

💡 Hint

Common Mistakes

Using em instead of rem when root-relative size is needed.

Using px which is fixed and not scalable.

The rem unit means relative to the root element's font size, so 1.5rem scales accordingly.

💡 Hint

Common Mistakes

Adding a number without units to a length with units.

Using a different unit like em which causes unit mismatch.

When adding lengths in Sass, both values must have units. So 10px is correct.

4fill in blank

hard

Fill both blanks to create a Sass map with font sizes in rem units for small and large text.

SASS

$font-sizes: (small: [1], large: [2]);

Drag options to blanks, or click blank then click option'

Swapping the small and large values.

The small font size is 0.875rem and the large font size is 2rem, both relative to root font size.

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using rem units for mobile width which is usually fixed in pixels.

Mixing up tablet and desktop widths.

The mobile width is 320px, tablet width is 768px, and desktop width is 64rem for scalable layout.
