3. Final Answer:

   Makes the grid item span 3 rows vertically. -> Option A

4. Quick Check:

   row-span-3 = span 3 rows [OK]

Hint: Remember: row-span controls vertical coverage [OK]

Common Mistakes:

• Confusing row-span with column-span
• Thinking it adds padding or margin
• Assuming it sets fixed height

2. Which of these is the correct Tailwind syntax to make a grid item span 2 rows?

easy

A. col-span-2

B. row-span-2

C. row-span2

D. span-row-2

Solution

1. Step 1: Recall Tailwind's row spanning syntax

   The correct format uses a dash: row-span-{number}.

2. Step 2: Check each option

   Only row-span-2 matches the correct syntax for spanning 2 rows.

3. Final Answer:

   row-span-2 -> Option B

4. Quick Check:

   Correct syntax = row-span-2 [OK]

Hint: Use dash between 'row-span' and number [OK]

• Using col-span instead of row-span
• Missing dash between words and number
• Reversing order of words

3. Given this HTML snippet inside a grid container:

<div class="grid grid-rows-4 grid-cols-2 gap-2">
  <div class="row-span-2 bg-blue-500">A</div>
  <div class="bg-red-500">B</div>

3. Final Answer:

   2 rows tall -> Option D

4. You wrote this code but the grid item does not span multiple rows:

<div class="grid grid-rows-3 grid-cols-3">
  <div class="row-span3 bg-purple-400">Item</div>
</div>

What is the error?

medium

A. Missing dash in row-span3, should be row-span-3.

B. Grid container needs grid-flow-row to enable spanning.

C. The grid must have grid-rows-4 to allow spanning 3 rows.

D. The item needs col-span-3 instead of row-span.

Solution

1. Step 1: Check the row-span class syntax

   The class is written as row-span3 but Tailwind requires a dash: row-span-3.

2. Step 2: Understand the effect of syntax error

   Without the dash, Tailwind ignores the class, so no spanning happens.

3. Final Answer:

   Missing dash in row-span3, should be row-span-3. -> Option A

4. Quick Check:

   Correct syntax needs dash [OK]

Hint: Always include dash between 'row-span' and number [OK]

Common Mistakes:

• Forgetting the dash in class names
• Assuming grid-rows count limits spanning
• Confusing row-span with col-span

C. grid grid-cols-3 grid-rows-4; item: row-span-2 col-span-2

D. grid grid-cols-3 grid-rows-4; item: row-span-3 col-span-1

2. Step 2: Make the item span 2 rows and 2 columns

   Use row-span-2 for vertical spanning and col-span-2 for horizontal spanning.

3. Final Answer:

Hint: Match grid size, then span rows and columns as needed [OK]

Common Mistakes:

• Mixing up grid-cols and grid-rows numbers
• Using wrong span numbers for item
• Forgetting to span columns when needed
