Why use variables for colors in Sass?

What is the main advantage of using variables to control colors in Sass instead of hardcoding color values everywhere?

A It disables the use of hex colors and only allows named colors.

B It allows changing a color in one place to update it everywhere automatically.

C It makes the CSS file size bigger because variables add extra code.

D It forces the browser to download colors separately, improving speed.

💡 Hint

Think about how easy it is to update a color used many times in your styles.

Using variables means you only change the color value once, and all places using that variable update automatically. This saves time and reduces mistakes.

Identify the correct Sass syntax for defining a color variable

Which of the following is the correct way to define a color variable in Sass?

A var main-color: #ff5733;

B main-color = #ff5733;

C $main-color: #ff5733;

Sass variables always start with a dollar sign ($) and use a colon to assign values.

What color will the button background be?

Given the Sass code below, what will be the background color of the button when compiled to CSS?

SASS

$base-color: #008080;
$button-bg: lighten($base-color, 20%);

button {
  background-color: $button-bg;
}

A #339999

B #006666

C #008080

D #33b3b3

💡 Hint

The lighten function makes the color lighter by the given percentage.

The lighten function increases the brightness of the base color by 20%, resulting in #33b3b3.

❓ selector

How to apply a programmatic color to multiple selectors?

You want to apply the same programmatic color variable to both h1 and h2 elements in Sass. Which selector syntax is correct?

A

h1, h2 {
  color: $heading-color;
}

B

h1 > h2 {
  color: $heading-color;
}

C

h1 + h2 {
  color: $heading-color;
}

D

h1 h2 {
  color: $heading-color;
}

💡 Hint

Think about how to select multiple elements separately.

Using a comma between selectors applies the styles to each separately. Other options select nested or adjacent elements.

❓ accessibility

Why is programmatic color control important for accessibility?

How does using programmatic color control in Sass help improve accessibility for users with visual impairments?

A It allows easy adjustment of color contrast ratios to meet accessibility standards.

B It automatically detects user vision problems and changes colors accordingly.

C It disables colors so screen readers can read text faster.

D It forces all colors to be grayscale, which is easier to see.

💡 Hint

Think about how changing colors in one place can help meet rules for readable text.

Programmatic color control lets developers quickly adjust colors to ensure enough contrast between text and backgrounds, making content easier to read for everyone.
