💡 Hint

Common Mistakes

Using 'order-sm-0' which does not reorder the column.

Using 'order-sm-3' which places the column last but may not be intended.

4fill in blank

hard

Fill both blanks to reorder columns: make the first column second and the second column first on extra large screens.

💡 Hint

Common Mistakes

Using 'order-xl-last' which places a column last but does not swap order.

Using the same order number for both columns.

Assigning 'order-xl-2' to the first column and 'order-xl-1' to the second column swaps their order on extra large screens.

5fill in blank

hard

Fill all three blanks to create a row with three columns where the middle column appears first, the last column second, and the first column last on large screens.

Bootsrap

<div class="row">
  <div class="col-lg-4 [1]">First</div>
  <div class="col-lg-4 [2]">Second</div>
  <div class="col-lg-4 [3]">Third</div>
</div>

Aorder-lg-3

Border-lg-1

Corder-lg-2

Dorder-lg-last

Attempts:

💡 Hint

Common Mistakes

Using 'order-lg-last' which always places a column last, not second.

Assigning the same order number to multiple columns.

Assigning 'order-lg-3' to the first column, 'order-lg-1' to the second, and 'order-lg-2' to the third column reorders them as requested on large screens.

Practice

1. What does Bootstrap's .order-* class do in a grid layout?

easy

A. It adds padding inside columns.

B. It changes the visual order of columns without altering the HTML structure.

C. It hides columns on smaller screens.

D. It changes the background color of columns.

Solution

1. Step 1: Understand the purpose of .order-* classes

   Bootstrap's .order-* classes let you rearrange columns visually without changing their HTML order.

2. Step 2: Compare with other options

   The other options describe unrelated styling or behavior, not column ordering.

3. Final Answer:

   It changes the visual order of columns without altering the HTML structure. -> Option B

4. Quick Check:

   Column ordering = Visual reorder without HTML change [OK]

Hint: Remember: .order-* changes visual order, not HTML order [OK]

Common Mistakes:

• Thinking .order-* changes HTML structure
• Confusing order with visibility or color
• Assuming it affects padding or margins

2. Which of the following is the correct syntax to make a column appear first using Bootstrap classes?

easy

A. class="col order-last"

B. class="col order-1"

C. class="col order-0"

D. class="col order-first"

Solution

1. Step 1: Recall Bootstrap order classes

   Bootstrap provides order-first to place a column first, order-last to place last, and numeric order-* from 0 to 12 for custom order.

2. Step 2: Analyze each option

   class="col order-1" uses order-1 which is not guaranteed first. class="col order-first" uses order-first which explicitly places the column first. class="col order-0" uses order-0 which is valid but less clear than order-first. class="col order-last" places the column last.

3. Final Answer:

   class="col order-first" -> Option D

4. Quick Check:

   Use order-first to place column first [OK]

Hint: Use order-first to make a column appear first easily [OK]

Common Mistakes:

• Using order-0 instead of order-first
• Confusing order-last with order-first
• Using invalid order numbers like order-13

3. Given this HTML snippet:

<div class="row">
  <div class="col order-3">A</div>
  <div class="col order-1">B</div>
  <div class="col order-2">C</div>
</div>

What is the visual order of columns on the page?

medium

A. B, C, A

B. A, B, C

C. C, B, A

D. B, A, C

Solution

1. Step 1: Understand order numbers

   Lower order numbers appear first visually. Here, B has order-1, C order-2, A order-3.

2. Step 2: Arrange columns by order

   Order from smallest to largest: B (1), C (2), A (3).

3. Final Answer:

   B, C, A -> Option A

4. Quick Check:

   Order numbers ascending = B, C, A [OK]

Hint: Lower order-* number means earlier visual position [OK]

Common Mistakes:

• Assuming HTML order is visual order
• Mixing up order numbers and column content
• Ignoring that order-1 is before order-2

4. You want the second column to appear first on small screens but keep original order on larger screens. Which class should you add?

medium

A. order-lg-first

B. order-first

C. order-sm-first

D. order-last

Solution

1. Step 1: Understand responsive order classes

   Bootstrap uses breakpoint prefixes like sm, md, lg to apply order changes at specific screen sizes.

2. Step 2: Match requirement to class

   To reorder only on small screens, use order-sm-first. order-first applies to all sizes. order-lg-first applies on large screens. order-last places last always.

3. Final Answer:

   order-sm-first -> Option C

4. Quick Check:

   Use order-sm-first for small screen reorder [OK]

Hint: Use order-sm-first to reorder only on small screens [OK]

Common Mistakes:

• Using order-first which affects all sizes
• Using order-lg-first which affects large screens
• Confusing order-last with order-first

5. You have three columns with classes:

<div class="col order-2 order-md-1">First</div>
<div class="col order-1 order-md-2">Second</div>
<div class="col order-3">Third</div>

How will the columns appear on small and medium screens respectively?

hard

A. Small: Second, First, Third; Medium: First, Second, Third

B. Small: First, Second, Third; Medium: Second, First, Third

C. Small: First, Second, Third; Medium: First, Second, Third

D. Small: Second, Third, First; Medium: First, Second, Third

Solution

1. Step 1: Analyze small screen order

   On small screens, order-* without breakpoint applies. So orders are: First=2, Second=1, Third=3. Visual order: Second (1), First (2), Third (3).

2. Step 2: Analyze medium screen order

   On medium screens, order-md-* overrides. First=1, Second=2, Third=3. Visual order: First, Second, Third.

3. Final Answer:

   Small: Second, First, Third; Medium: First, Second, Third -> Option A

4. Quick Check:

   Breakpoint order overrides default order [OK]

Hint: Breakpoint-specific order overrides default order [OK]

Common Mistakes:

• Ignoring breakpoint-specific order classes
• Assuming order-md-* applies on small screens
• Mixing up order numbers and visual positions
