2. Which Bootstrap class is used to add basic styling to a table for better readability?

easy

A. form-control

B. btn-primary

C. table-striped

D. text-center

Solution

1. Step 1: Identify Bootstrap classes related to tables

   Bootstrap uses classes like table-striped to style tables with alternating row colors.

2. Step 2: Match class to purpose

   btn-primary styles buttons, text-center centers text, and form-control styles form inputs, so they don't style tables.

3. Final Answer:

   table-striped -> Option C

4. Quick Check:

   Table styling class = table-striped [OK]

Hint: Remember table classes start with 'table-' in Bootstrap [OK]

Common Mistakes:

• Confusing text alignment with table styling

B. It changes the table background color

C. It hides the table header

D. It makes the table text bold

Solution

1. Step 1: Understand the table-bordered class effect

   This class adds visible borders around each cell in the table, making the structure clearer.

2. Step 2: Compare with other options

   Changing background color is done by other classes, hiding header or bold text are unrelated to table-bordered.

3. Final Answer:

   It adds borders around all table cells -> Option A

4. Quick Check:

   table-bordered = cell borders visible [OK]

Hint: Borders mean lines around cells, so table-bordered adds them [OK]

Common Mistakes:

• Thinking it changes background color
• Assuming it hides parts of the table
• Confusing with text formatting classes

4. You added class="table-striped" to your table but see no alternating row colors. What is the likely problem?

medium

A. You forgot to include Bootstrap CSS in your HTML

B. You used table-striped on a div instead of a table

C. You need to add table-bordered too

D. You must add text-center for colors to show

Solution

1. Step 1: Check if Bootstrap CSS is loaded

   Without Bootstrap CSS, none of its classes will style elements, so table-striped won't work.

2. Step 2: Understand correct usage

   Using table-striped on a div won't work because it styles table elements. But the main cause is missing CSS.

3. Final Answer:

   You forgot to include Bootstrap CSS in your HTML -> Option A

4. Quick Check:

   Missing CSS = no Bootstrap styles applied [OK]

Hint: Always check if Bootstrap CSS file is linked first [OK]

Common Mistakes:

• Thinking multiple classes are needed for stripes
• Applying table classes to wrong HTML tags
• Believing text alignment affects colors

5. You want to display a list of products with their prices clearly using Bootstrap. Which combination best improves readability and user experience?

Solution

1. Step 1: Choose the right HTML structure for tabular data

   Products and prices fit well in a table because it organizes rows and columns clearly.

2. Step 2: Apply Bootstrap classes for styling

   table-striped adds alternating row colors, and table-bordered adds borders, both improving readability and user experience.

3. Final Answer:

   Use a table with table-striped and table-bordered classes -> Option B

4. Quick Check:

   Structured data + Bootstrap table classes = clear display [OK]

Hint: Tables + Bootstrap styling = best for structured data display [OK]

Common Mistakes:
