Practice

1. Which Bootstrap class would you use to make text color red?

easy

A. bg-red

B. text-danger

C. text-red

D. bg-danger

Solution

1. Step 1: Understand Bootstrap text color classes

   Bootstrap uses text-{color} classes to change text color, where {color} is a predefined color name.

2. Step 2: Identify the correct class for red text

   The class text-danger applies a red color to text. The other options either apply background color or use incorrect class names.

3. Final Answer:

   text-danger -> Option B

4. Quick Check:

   Text color red = text-danger [OK]

Hint: Text color uses text-{color}, background uses bg-{color} [OK]

Common Mistakes:

• Confusing text and background classes
• Using non-existent classes like text-red
• Using bg-danger for text color

2. Which of the following is the correct syntax to set a blue background using Bootstrap?

easy

A. bg-blue

B. text-primary

C. background-blue

Solution

1. Step 1: Recall Bootstrap background color classes

   Bootstrap uses bg-{color} classes to set background colors, where {color} is a predefined color name.

2. Step 2: Identify the correct class for blue background

   The class bg-primary sets a blue background. The other options either set text color or use invalid class names.

3. Final Answer:

   bg-primary -> Option D

4. Quick Check:

Common Mistakes:

• Using text-primary for background

4. You want to set a yellow background but wrote bg-warningg. What will happen?

medium

A. The text color will change to yellow

B. The background will be yellow as expected

C. The background will be transparent (no color)

D. The page will show an error

Solution

1. Step 1: Check the class name spelling

   The correct class for yellow background is bg-warning, but bg-warningg has an extra 'g' and is invalid.

2. Step 2: Understand how browsers handle invalid classes

   Invalid classes are ignored by the browser, so no background color will be applied, resulting in transparent background.

3. Final Answer:

   The background will be transparent (no color) -> Option C

4. Quick Check:

   Invalid class = no style applied [OK]

Hint: Check spelling carefully; invalid classes do nothing [OK]

Common Mistakes:

• Assuming a typo still applies the color
• Expecting an error message in browser
• Confusing background and text color effects

   The class text-white sets the text color to white.

3. Step 3: Combine classes for desired effect

   Using btn bg-danger text-white applies a red background and white text on the button.

4. Final Answer:

   class="btn bg-danger text-white" -> Option A

5. Quick Check:

   Red background + white text = bg-danger + text-white [OK]

Hint: Background red = bg-danger, white text = text-white [OK]

Common Mistakes:

• Mixing text-danger (red text) with bg-danger (red background)
• Using bg-white for background when red is needed
• Using same color for text and background causing unreadable text
