Common Mistakes

Using col-start-2 only changes the start column, not the span.

Using col-end-3 is about ending position, not span.

Using col-span-3 spans all columns, not 2.

Using col-span-2 makes the grid item span across 2 columns.

Common Mistakes

Using col-span-2 spans fewer columns than needed.

Using col-span-4 spans all columns, not 3.

💡 Hint

Common Mistakes

Using col-span-4 in a 3-column grid causes layout issues.

Using col-start-2 only changes start position.

Using col-end-3 is not for spanning columns.

The correct class to span 2 columns is col-span-2. Other options cause errors or don't span correctly.

4fill in blank

Fill both blanks to make the first item span 2 columns and the second item span 3 columns.

Tailwind

<div class="grid grid-cols-5 gap-4">

💡 Hint

Common Mistakes

Using col-span-4 for the first item spans too many columns.

Using col-start-2 does not control span.

Mixing up the spans between items.

Use col-span-2 for the first item and col-span-3 for the second item to span the correct number of columns.

5fill in blank

hard

Fill all three blanks to create a grid where the first item spans 3 columns, the second item spans 1 column, and the third item spans 2 columns.

Tailwind

<div class="grid grid-cols-6 gap-2">
  <div class="[1]">Item 1</div>
  <div class="[2]">Item 2</div>
  <div class="[3]">Item 3</div>

💡 Hint

Common Mistakes

Using col-start-2 instead of a span class.

Assigning wrong span numbers that don't add up.

Using the same span for all items.

Assign col-span-3 to the first item, col-span-1 to the second, and col-span-2 to the third to match the required spans.

Practice

1. What does the Tailwind class col-span-3 do in a grid layout?

easy

A. Creates 3 columns inside the element

B. Adds 3 columns to the grid container

C. Makes the element span across 3 columns in the grid

D. Sets the element width to 3rem

Solution

1. Step 1: Understand the role of col-span-{n}

   The class col-span-3 tells the element to cover 3 columns in the grid layout.

2. Step 2: Differentiate from other grid classes

   It does not create columns or set width; it only controls how many columns the element spans.

3. Final Answer:

   Makes the element span across 3 columns in the grid -> Option C

4. Quick Check:

   col-span-3 = span 3 columns [OK]

Hint: Remember col-span controls how many columns an item covers [OK]

Common Mistakes:

• Confusing col-span with grid-cols which sets columns on container
• Thinking col-span creates columns inside the element
• Assuming col-span sets fixed width in rem or px

2. Which of the following is the correct way to make a grid container with 4 columns and an item that spans 2 columns in Tailwind?

easy

A. Item

B. Item

C. Item

D. Item

Solution

1. Step 1: Set up the grid container with 4 columns

   The class grid-cols-4 inside a grid container creates 4 columns.

2. Step 2: Make the item span 2 columns

   The class col-span-2 on the item makes it cover 2 columns.

3. Final Answer:

   <div class='grid grid-cols-4'><div class='col-span-2'>Item</div></div> -> Option B

4. Quick Check:

   grid-cols-4 + col-span-2 = correct syntax [OK]

Hint: Use grid-cols on container, col-span on item [OK]

Common Mistakes:

• Swapping order of grid and grid-cols classes
• Using incorrect class like span-col-2 instead of col-span-2
• Setting col-span larger than grid-cols

3. Given this code snippet, what will be the visual layout of the grid items?

<div class='grid grid-cols-3 gap-4'>
  <div class='col-span-2 bg-blue-300'>A</div>
  <div class='bg-red-300'>B</div>
  <div class='bg-green-300'>C</div>
</div>

medium

A. Item A spans 2 columns in the first row, B occupies the third column in the first row, C starts a new row

B. Items A, B, and C all appear in the first row, each spanning one column

C. Item A spans 3 columns, B and C are below in separate rows

D. Item A spans 2 rows, B and C are side by side in the first row

Solution

1. Step 1: Analyze grid container and columns

   The container has 3 columns with gaps. Item A spans 2 columns, so it fills columns 1 and 2 in the first row.

2. Step 2: Position of items B and C

   Item B fills the remaining 1 column in the first row (column 3). Item C moves to the next row occupying the first column.

3. Final Answer:

   Item A spans 2 columns in the first row, B occupies the third column in the first row, C starts a new row -> Option A

4. Quick Check:

   col-span-2 + grid-cols-3 layout = Item A spans 2 columns in the first row, B occupies the third column in the first row, C starts a new row [OK]

Hint: Count columns and span to place items visually [OK]

Common Mistakes:

• Assuming all items fit in one row regardless of span
• Thinking col-span affects rows instead of columns
• Ignoring grid gaps affecting spacing

4. Identify the error in this Tailwind grid code:

<div class='grid grid-cols-3'>
  <div class='col-span-4 bg-yellow-200'>Item 1</div>
  <div>Item 2</div>
</div>

medium

A. col-span-4 is invalid because the grid has only 3 columns

B. Missing gap class for spacing between columns

C. The grid container is missing the grid class

D. The second div should also have a col-span class

Solution

1. Step 1: Check grid container columns

   The container has 3 columns defined by grid-cols-3.

2. Step 2: Validate col-span value

   The item uses col-span-4, which tries to span 4 columns, exceeding the 3 columns available.

3. Final Answer:

   col-span-4 is invalid because the grid has only 3 columns -> Option A

4. Quick Check:

   col-span cannot exceed grid-cols [OK]

Hint: col-span must be ≤ grid-cols count [OK]

Common Mistakes:

• Ignoring that col-span cannot be larger than grid-cols
• Thinking missing gap causes layout error
• Assuming grid class is missing when it is present

5. You want to create a responsive grid where an item spans 4 columns on large screens but only 2 columns on small screens. Which Tailwind classes achieve this?

hard

A. grid grid-cols-6 col-span-2 sm:col-span-4

B. grid grid-cols-4 col-span-4 sm:col-span-2

C. grid grid-cols-6 col-span-4 sm:col-span-2

D. grid grid-cols-6 col-span-2 lg:col-span-4

Solution

1. Step 1: Define grid with enough columns

   Using grid-cols-6 gives 6 columns, enough for spanning 4 columns on large screens.

2. Step 2: Set default and large screen spans

   col-span-2 applies by default (small screens). lg:col-span-4 overrides on large screens to span 4 columns.

3. Final Answer:

   grid grid-cols-6 col-span-2 lg:col-span-4 -> Option D

4. Quick Check:

   Responsive col-span with lg: prefix = grid grid-cols-6 col-span-2 lg:col-span-4 [OK]

Hint: Use responsive prefixes like lg: for different spans [OK]

Common Mistakes:

• Using sm: prefix for large screen changes
• Setting col-span larger than grid-cols
• Not defining enough columns in grid-cols
