Why use a separate print stylesheet in Sass?

Which of the following best explains the main reason to organize a separate print stylesheet in Sass?

A To optimize styles specifically for printed pages, improving readability and layout when printing.

B To apply animations and transitions only when printing documents.

C To reduce the overall file size of the main stylesheet by removing unused styles.

D To enable JavaScript to dynamically change styles during printing.

💡 Hint

Think about how printed pages differ from screens in style needs.

Print stylesheets focus on adjusting layout and colors for paper, making printed content clear and readable. This is why they are separated.

📝 Syntax

Correct syntax for print media query in Sass

Which option shows the correct way to write a print media query in Sass to style printed pages?

SASS

@media print {
  body {
    font-size: 12pt;
  }
}

A

@media only print {
  body {
    font-size: 12pt;
  }
}

B

@media screen and print {
  body {
    font-size: 12pt;
  }
}

C

@media (print) {
  body {
    font-size: 12pt;
  }
}

D

@media print {
  body {
    font-size: 12pt;
  }
}

💡 Hint

Remember the standard media query syntax for print.

The correct syntax for targeting print media is @media print { ... }. Other options are either invalid or target multiple media types.

❓ layout

Effect of print styles on page layout

Given this Sass print stylesheet snippet, what will be the visual effect when printing?

@media print {
  nav, footer {
    display: none;
  }
  main {
    width: 100%;
  }
}

A Navigation and footer will be hidden, but main content width remains unchanged.

B Navigation and footer will be visible, but main content width will shrink.

C Navigation and footer will be hidden, and main content will expand to full page width.

D Only footer will be hidden; navigation remains visible with reduced width.

💡 Hint

Consider what happens when elements are set to display none and width 100%.

Setting display: none hides nav and footer from print. Setting width: 100% on main makes it fill the available page width.

❓ accessibility

advanced

Accessibility considerations in print stylesheets

Which practice improves accessibility when organizing print stylesheets in Sass?

A Ensure high contrast colors and readable font sizes for printed text.

B Use only light gray text to save printer ink.

C Hide all images to reduce printing time.

D Use very small fonts to fit more content on each page.

💡 Hint

Think about what makes printed text easy to read for everyone.

High contrast and readable font sizes help users with visual impairments read printed content easily. Other options reduce readability or accessibility.

❓ selector

expert

Which selector targets only printed links in Sass?

In a Sass print stylesheet, which selector correctly styles only links when printing?

A @media print { a:hover { color: black; } }

B @media print { a { color: black; text-decoration: underline; } }

C @media print { a:link { color: black; } }

D @media print { a:visited { color: black; } }

💡 Hint

Consider which pseudo-classes apply in print media.

In print media, pseudo-classes like :hover do not apply. The base a selector styles all links for print.

Practice

1. What is the main purpose of a print stylesheet in web development?

easy

A. To make the webpage look good when printed on paper

B. To add animations to the webpage

C. To improve website loading speed

D. To change the webpage's background color on screen

Solution

1. Step 1: Understand what print stylesheets do

   Print stylesheets adjust the webpage's appearance specifically for printing on paper.

2. Step 2: Compare options to the purpose

   Only To make the webpage look good when printed on paper matches the purpose of print stylesheets, which is to make pages look good on paper.

3. Final Answer:

   To make the webpage look good when printed on paper -> Option A

4. Quick Check:

   Print stylesheets = good print appearance [OK]

Hint: Print stylesheets improve printed page look, not screen effects [OK]

Common Mistakes:

• Confusing print stylesheets with screen stylesheets
• Thinking print stylesheets add animations
• Assuming print stylesheets speed up loading

2. Which of the following is the correct way to write a print media query in Sass?

easy

A. @media print { body { font-size: 12pt; } }

B. @media screen { body { color: black; } }

C. @media all { body { background: white; } }

D. @media handheld { body { font-weight: bold; } }

Solution

1. Step 1: Identify the print media query syntax

   The correct syntax for print styles is @media print { ... }.

2. Step 2: Match the option with print media query

   @media print { body { font-size: 12pt; } } uses @media print correctly with a style inside.

3. Final Answer:

   @media print { body { font-size: 12pt; } } -> Option A

4. Quick Check:

   Print media query syntax = @media print [OK]

Hint: Use '@media print' to target print styles in Sass [OK]

Common Mistakes:

• Using '@media screen' instead of '@media print'
• Forgetting curly braces after '@media print'
• Using unsupported media types like 'handheld'

3. Given this Sass code, what will be the font size of paragraphs when printed?

@media print {
  p {
    font-size: 14pt;
  }
}
p {
  font-size: 16px;
}

medium

A. 14px

B. 16px

C. 16pt

D. 14pt

Solution

1. Step 1: Understand media query effect on print

   The @media print block applies only when printing, overriding other styles.

2. Step 2: Compare font sizes inside and outside print query

   Outside print, paragraphs have 16px font size; inside print, 14pt is set, which applies when printing.

3. Final Answer:

   14pt -> Option D

4. Quick Check:

   Print font size = 14pt [OK]

Hint: Print styles override screen styles inside '@media print' [OK]

Common Mistakes:

• Confusing px and pt units
• Ignoring media query overrides
• Assuming screen styles apply when printing

4. Identify the error in this Sass print stylesheet code:

@media print {
  .hide-on-print {
    display: none
  }
}

medium

A. Cannot use 'display: none' in print styles

B. Wrong media type, should be '@media screen'

C. Missing semicolon after 'display: none'

D. Class selector should start with '#' instead of '.'

Solution

1. Step 1: Check CSS syntax inside '@media print'

   Every CSS property must end with a semicolon; here, 'display: none' misses it.

2. Step 2: Verify other options

   Media type '@media print' is correct, class selectors use '.', and 'display: none' is valid in print styles.

3. Final Answer:

   Missing semicolon after 'display: none' -> Option C

4. Quick Check:

   CSS properties need semicolons [OK]

Hint: Always end CSS declarations with semicolons [OK]

Common Mistakes:

• Omitting semicolons in CSS blocks
• Confusing class selectors with ID selectors
• Using wrong media types for print styles

5. You want to hide navigation menus and change font size only when printing. Which Sass structure correctly organizes these print styles?

hard

A. nav { display: none; }
body { font-size: 12pt; }

B. @media print {
nav { display: none; }
body { font-size: 12pt; }
}

C. @media screen {
nav { display: none; }
body { font-size: 12pt; }
}

D. @media print {
nav { font-size: 12pt; }
body { display: none; }
}

Solution

1. Step 1: Identify correct media query for print styles

   Print styles must be inside @media print { ... } to apply only when printing.

2. Step 2: Check style rules for hiding nav and changing font size

   @media print { nav { display: none; } body { font-size: 12pt; } } hides nav with display: none; and sets font size on body inside print media query, which is correct.

3. Final Answer:

   @media print { nav { display: none; } body { font-size: 12pt; } } -> Option B

4. Quick Check:

   Print styles inside '@media print' with correct selectors [OK]

Hint: Group all print styles inside '@media print' block [OK]

Common Mistakes:

• Placing print styles outside '@media print'
• Using '@media screen' instead of print
• Mixing display and font-size on wrong selectors
