💡 Hint

Common Mistakes

Using 'screen' instead of 'print' will apply styles only on screens, not print.

Using 'all' applies styles everywhere, not just print.

The @media print rule targets styles specifically for printed documents.

  .no-print {
    [1]: none;

💡 Hint

Common Mistakes

Using 'visibility: none' is invalid CSS.

Using 'opacity: none' is invalid; opacity uses numbers.

Setting display: none; hides the element completely in print.

3fill in blank

hard

Fix the error in the print media query syntax.

SASS

@media [1] {
  p {
    color: black;
  }
}

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

Bprint screen

Cscreen

Dprint;

💡 Hint

Common Mistakes

Adding a semicolon after 'print' causes a syntax error.

Using 'print screen' is not a valid media type.

The media type should not have a semicolon inside the @media rule.

4fill in blank

hard

Fill both blanks to create a Sass mixin for print styles and include it.

SASS

@mixin [1] {
  @media [2] {
    @content;
  }
}

@include print-styles;

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

Aprint-styles

Bscreen

Cprint

Dscreen-only

💡 Hint

Common Mistakes

Using 'screen' instead of 'print' will not target print media.

Mismatch between mixin name and include name causes errors.

The mixin is named print-styles and uses @media print to target print media.

5fill in blank

hard

Fill all three blanks to create a print-specific style for links inside a Sass print mixin.

SASS

@mixin print-styles {
  @media [1] {
    a {
      color: [2];
      text-decoration: [3];
    }
  }
}

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

💡 Hint

Common Mistakes

Using 'screen' media type will not apply styles to print.

Setting text-decoration to 'none' removes underlines.

The media type is 'print'. Links are colored blue and have no underline in 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
