   The main goal is to make headings stand out by increasing their size and weight, not to change colors or add animations.

3. Final Answer:

   To make headings larger and more prominent on the page -> Option D

4. Quick Check:

   Display classes = bigger, bold headings [OK]

B. <h1 display-3>Title</h1>

C. <h1 class="display-3">Title</h1>

D. <h1 class="title display3">Title</h1>

Solution

1. Step 1: Recall Bootstrap class syntax

   Bootstrap classes are added using the class attribute with the exact class name, e.g., class="display-3".

2. Step 2: Check each option for correct syntax

   <h1 class="display-3">Title</h1> uses class="display-3" correctly. Other options misuse attribute syntax or class names.

3. Final Answer:

   <h1 class="display-3">Title</h1> -> Option C

4. Quick Check:

3. What will be the visual difference between these two headings in a Bootstrap page?

<h2 class="display-1">Big Heading</h2>
<h2>Normal Heading</h2>

medium

A. The 'Big Heading' text will be much larger and bolder than 'Normal Heading'.

B. Both headings will look the same size and weight.

C. 'Normal Heading' will be larger than 'Big Heading'.

D. 'Big Heading' will be hidden on small screens.

Solution

1. Step 1: Understand the effect of display-1 class

   The display-1 class makes text very large and bold compared to normal heading styles.

2. Step 2: Compare the two headings visually

   The first heading with display-1 will appear much bigger and bolder than the second heading without any display class.

3. Final Answer:

   The 'Big Heading' text will be much larger and bolder than 'Normal Heading'. -> Option A

4. Quick Check:

   display-1 = biggest heading style [OK]

Hint: Display-1 is the largest heading style in Bootstrap [OK]

Common Mistakes:

• Assuming display classes do not change size
• Thinking normal headings are bigger
• Confusing display classes with visibility classes

4. Identify the error in this Bootstrap heading code:

<h3 class="display5">Heading</h3>

medium

A. The <h3> tag cannot use display classes

B. The class name should be display-4 with a dash, not display5

C. The heading text must be inside a <div> to use display classes

D. The class attribute is missing quotes

Solution

1. Step 1: Check Bootstrap display class naming

   Bootstrap display classes use a dash, e.g., display-1, display-2, up to display-4. There is no display5 class.

2. Step 2: Identify the mistake in the code

   The code uses display5 without a dash, which is invalid and will not apply the style.

3. Final Answer:

   The class name should be display-4 with a dash, not display5 -> Option B

4. Quick Check:

   Display classes require dash, e.g., display-1 [OK]

Hint: Remember display classes have a dash: display-1, display-2, etc. [OK]

Common Mistakes:

• Omitting the dash in class names
• Thinking display classes only work on <h1>
• Missing quotes around class attribute

5. You want to create a page with a main heading that is very large and bold, and a subheading that is smaller but still styled with Bootstrap display classes. Which combination is correct?

hard

A. <h1 class="display-1">Main Title</h1> <h2 class="display-4">Sub Title</h2>

B. <h1 class="display-4">Main Title</h1> <h2 class="display-1">Sub Title</h2>

C. <h1>Main Title</h1> <h2>Sub Title</h2>

D. <h1 class="display-5">Main Title</h1> <h2 class="display-3">Sub Title</h2>

Solution

1. Step 1: Understand Bootstrap display class sizes

   Display classes range from display-1 (largest) to display-4 (smaller). There is no display-5.

2. Step 2: Choose correct class order for main and subheading

   Main heading should use display-1 for biggest size, subheading can use display-4 for smaller but styled text.

3. Step 3: Verify semantic tags and classes

   <h1 class="display-1">Main Title</h1> <h2 class="display-4">Sub Title</h2> uses correct classes and semantic tags. Other combinations either use non-existent classes like display-5, reverse the size order (smaller main heading with display-4, larger subheading with display-1), or omit display classes entirely.

4. Final Answer:

   <h1 class="display-1">Main Title</h1> <h2 class="display-4">Sub Title</h2> -> Option A
