💡 Hint

Common Mistakes

Using variable names as values instead of actual colors.

Forgetting the # in hex color codes.

The variable $primary-color should be assigned a valid color value like #3498db. This allows consistent use of the primary color throughout the styles.

💡 Hint

Common Mistakes

Using 100vw which can cause horizontal scroll.

Using auto which does not limit width.

The max-width of a container is often set to a fixed pixel value like 1200px to limit content width on large screens while centering it.

Fix the nested selector to add hover styles for links inside a nav.

SASS

nav {
  a {
    color: $primary-color;
    [1] {
      text-decoration: none;
    }
  }
}

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

C&:link

D:hover

💡 Hint

Common Mistakes

Using :hover without &, resulting in invalid selector.

Using pseudo-classes at the wrong nesting level.

To target the hover state on links inside nav, nest &:hover inside the a selector. This compiles to nav a:hover { text-decoration: none; }.

4fill in blank

Fill both blanks to create a map of breakpoints and use it in a media query.

SASS

$breakpoints: (small: [1], large: [2]);

@media (min-width: map-get($breakpoints, small)) {
  body { font-size: 1rem; }
}

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

A480px

B768px

C1024px

D1200px

💡 Hint

Common Mistakes

Mixing up small and large breakpoint values.

Using invalid units or missing px.

The map defines breakpoints for responsive design. small is often around 480px and large around 1200px. The media query uses the small breakpoint.

5fill in blank

hard

Fill all three blanks to create a function that darkens a color by a percentage.

SASS

@function darken-color($color, $amount) {
  @return [1]($color, $amount * [2]);
}

$dark-primary: darken-color($primary-color, [3]);

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

💡 Hint

Common Mistakes

Using lighten instead of darken.

Not converting the percentage number to decimal (multiply by 0.01).

Passing percentage as '20%' with % sign instead of number 20.

The darken function in Sass darkens a color by a percentage (decimal). Multiplying $amount (20) by 0.01 converts it to a decimal (0.2). Calling with 20 darkens by 20 percent.
