4. Quick Check:

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

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

   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.

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

4. Quick Check:

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

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>

   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
