1. Which Bootstrap class would you use to create the largest display heading?

easy

A. lead

B. display-4

C. h1

D. display-1

Solution

1. Step 1: Understand Bootstrap display classes

   Bootstrap provides display classes from display-1 to display-4, where display-1 is the largest size.

2. Step 2: Identify the largest display class

   Among the options, display-1 is the biggest heading style.

3. Final Answer:

   display-1 -> Option D

4. Quick Check:

   Largest display heading = display-1 [OK]

Hint: Remember display-1 is biggest, display-4 is smallest [OK]

Common Mistakes:

• Choosing display-4 thinking higher number means bigger
• Using lead which styles paragraphs, not headings

2. Which of the following is the correct way to apply a Bootstrap display heading class to an h2 element?

easy

A. <h2 class='display-2'>Hello</h2>

B. <h2 display-2>Hello</h2>

C. <h2 class='display2'>Hello</h2>

D. <h2 class='display-5'>Hello</h2>

Solution

1. Step 1: Check correct class syntax

   Bootstrap display classes use the format display-1 to display-4 and must be added inside the class attribute.

2. Step 2: Validate each option

   <h2 class='display-2'>Hello</h2> uses class='display-2' correctly. <h2 display-2>Hello</h2> misses class=. <h2 class='display2'>Hello</h2> uses wrong class name display2. <h2 class='display-5'>Hello</h2> uses invalid class display-5 which doesn't exist.

3. Final Answer:

   <h2 class='display-2'>Hello</h2> -> Option A

4. Quick Check:

   Use class='display-x' with x from 1 to 4 [OK]

C. The text will be smaller and lighter with display-3 class.

D. The text will be italicized with display-3 class.

Solution

1. Step 1: Understand Bootstrap display classes effect

   Display classes increase font size and weight to make headings stand out more than default heading tags.

2. Step 2: Compare default h3 with display-3

   Using display-3 on h3 makes the text bigger and bolder than the normal h3 style.

3. Final Answer:

   The text will be larger and bolder with display-3 class. -> Option B

4. Quick Check:

   Display classes enlarge and bold headings [OK]

4. Identify the error in this code snippet: <h1 class='display-5'>Welcome</h1>

medium

A. The h1 tag cannot have classes.

B. The class name should be display_5 with underscore.

C. The class display-5 does not exist in Bootstrap.

D. The text 'Welcome' should be inside a span.

Solution

1. Step 1: Verify Bootstrap display classes range

   Bootstrap display classes only go from display-1 to display-4. There is no display-5.

2. Step 2: Check other options for validity

   The h1 tag cannot have classes. is false because h1 can have classes. The class name should be display_5 with underscore. is incorrect because Bootstrap uses dashes, not underscores. The text 'Welcome' should be inside a span. is unnecessary; text can be directly inside h1.

3. Final Answer:

   The class display-5 does not exist in Bootstrap. -> Option C

4. Quick Check:

   Display classes only from display-1 to display-4 [OK]

Hint: Check Bootstrap docs for valid display class numbers [OK]

Common Mistakes:

• Using non-existent display classes like display-5
• Thinking class names can have underscores
• Believing headings can't have classes

5. You want a heading that is visually large using Bootstrap but semantically an h4 for accessibility. Which is the best way to do this?

hard

A. <h4 class='display-1'>Big Heading</h4>

B. <h1 class='display-4'>Big Heading</h1>

C. <div class='display-1'>Big Heading</div>

D. <h4 style='font-size: 3rem;'>Big Heading</h4>

Solution

1. Step 1: Understand semantic vs visual roles

   For accessibility, the heading tag (h4) should reflect the document structure. Visual size can be changed with Bootstrap classes.

2. Step 2: Evaluate options for semantic correctness and styling

   <h4 class='display-1'>Big Heading</h4> keeps h4 semantic tag and applies display-1 for large style. <h1 class='display-4'>Big Heading</h1> uses h1 which changes semantics. <div class='display-1'>Big Heading</div> uses div which is not semantic heading. <h4 style='font-size: 3rem;'>Big Heading</h4> uses inline style, not Bootstrap class.

3. Final Answer:

   <h4 class='display-1'>Big Heading</h4> -> Option A

4. Quick Check:

   Use semantic tag + display class for size [OK]

Hint: Use heading tag for structure, display class for size [OK]

Common Mistakes:

• Changing heading tag to bigger one for size
• Using non-semantic tags for headings
• Relying on inline styles instead of Bootstrap classes
