The image uses card-img-top, the title uses card-title, and the button uses btn-primary for a blue styled button.

Solution

1. Step 1: Understand the purpose of cards

   Cards are designed to group related content visually in a box format.

2. Step 2: Compare options with card features

B. .card

C. .box-card

D. .card-container

   Bootstrap card class = .card [OK]

Hint: Bootstrap cards use the class .card for containers [OK]

Solution

1. Step 1: Analyze card structure

   The card has an image on top, a body with a title, text, and a button styled with Bootstrap classes.

2. Step 2: Understand Bootstrap styling

   The btn btn-primary class creates a blue button, and the card groups all content in a box.

3. Final Answer:

   A box with an image on top, a title, text, and a blue button inside. -> Option A

<div class="card">
  <div class="card-body">
    <h5 class="card-title">Title</h5>
    <p class="card-text">Text here</p>
  </div>
  <img src="pic.jpg" class="card-img-top" alt="Image">
</div>

medium

A. The card-title class is invalid and should be removed.

B. The card class must be applied to the image, not the div.

C. The card-text class should be on the div, not the paragraph.

D. The image should be placed before the card body inside the card.

Solution

1. Step 1: Review Bootstrap card image placement

   Bootstrap expects the image with card-img-top to be placed before the card body for correct layout.

2. Step 2: Check other classes usage

   The card-title and card-text classes are correctly used on heading and paragraph respectively.

3. Final Answer:

   The image should be placed before the card body inside the card. -> Option D

4. Quick Check:

   Image placement before body = B [OK]

Hint: Place .card-img-top before .card-body inside .card [OK]

Common Mistakes:

• Putting image after card body breaks layout
• Removing valid card-title or card-text classes
• Misapplying card class to image

5. You want to create a responsive Bootstrap card layout that shows three cards side by side on large screens but stacks them vertically on small screens. Which Bootstrap classes should you use to organize the cards correctly?

hard

A. Use grid with three col-4 col-12 cards inside.

B. Use container with three card-lg-4 card-12 inside.

C. Use row with three col-lg-4 col-12 cards inside.

D. Use flex-row with three card-4 card-12 inside.

Solution

1. Step 1: Understand Bootstrap grid for responsiveness

   Bootstrap uses row and col-* classes to create responsive layouts.

2. Step 2: Choose correct column classes for screen sizes

   col-lg-4 makes each card take 1/3 width on large screens, and col-12 makes them full width on small screens, stacking vertically.

3. Final Answer:

   Use row with three col-lg-4 col-12 cards inside. -> Option C

4. Quick Check:

   Responsive columns use col-lg-4 and col-12 inside row = D [OK]

Hint: Combine row with col-lg-4 and col-12 for responsive cards [OK]

Common Mistakes:

• Using incorrect class names like card-lg-4
• Confusing flex-row with Bootstrap grid row
• Using grid without proper Bootstrap classes
