Common Mistakes

Using a number other than 3 for the columns.

Forgetting to add the grid class.

The class grid-cols-3 sets the grid to have 3 columns.

2fill in blank

medium

Tailwind

<div class="grid grid-cols-[1] gap-[2]">
  <div class="bg-yellow-400">Item A</div>
  <div class="bg-pink-400">Item B</div>
  <div class="bg-purple-400">Item C</div>

💡 Hint

Common Mistakes

Using the wrong number for columns or gap.

Mixing up gap and padding classes.

The class grid-cols-4 sets 4 columns, and gap-6 sets the gap size between grid items.

3fill in blank

hard

Fix the error in the code to make the grid automatically create columns with a minimum width of 10rem using Tailwind CSS.

Tailwind

<div class="grid grid-cols-[1] gap-4">
  <div class="bg-gray-300">Box 1</div>
  <div class="bg-gray-400">Box 2</div>
  <div class="bg-gray-500">Box 3</div>
</div>

Drag options to blanks, or click blank then click option'

A[repeat(auto-fill,minmax(10rem,1fr))]

B[auto-fit_minmax(10rem,_1fr)]

C[repeat(auto-fit,minmax(10rem,1fr))]

D[repeat(auto-fill,minmax(10rem,2fr))]

Attempts:

💡 Hint

Common Mistakes

Forgetting repeat() wrapper.

Using spaces incorrectly or auto-fit instead of auto-fill.

Not using square brackets for arbitrary values.

In Tailwind CSS, to use custom grid-template-columns with repeat(auto-fill, minmax) for responsive implicit grid sizing, you wrap the valid CSS value in square brackets: grid-cols-[repeat(auto-fill,minmax(10rem,1fr))] is correct.

4fill in blank

hard

Fill both blanks to create a grid that automatically fits columns with a minimum width of 12rem and a gap of 8.

Tailwind

<div class="grid grid-cols-[1] gap-[2]">
  <div class="bg-red-200">Item 1</div>
  <div class="bg-red-400">Item 2</div>
  <div class="bg-red-600">Item 3</div>
  <div class="bg-red-800">Item 4</div>
</div>

Drag options to blanks, or click blank then click option'

A[repeat(auto-fit,minmax(12rem,1fr))]

💡 Hint

Common Mistakes

Using gap-6 instead of gap-8.

Omitting repeat() in the grid columns value.

Not using square brackets for the custom grid columns.

The class grid-cols-[repeat(auto-fit,minmax(12rem,1fr))] sets the grid to automatically fit columns with a minimum width of 12rem. The class gap-8 sets the gap size between items.

5fill in blank

hard

Fill all three blanks to create a responsive grid that uses auto-fill with a minimum column width of 14rem, a gap of 10, and a background color of blue-100.

Tailwind

<div class="grid grid-cols-[1] gap-[2] bg-[3]">
  <div>Box A</div>
  <div>Box B</div>
  <div>Box C</div>
  <div>Box D</div>
</div>

Drag options to blanks, or click blank then click option'

A[repeat(auto-fill,minmax(14rem,1fr))]

B10

Cblue-100

Dblue-200

Attempts:

3 left

💡 Hint

Common Mistakes

Using blue-200 instead of blue-100 for background.

Omitting repeat() for the custom grid columns.

The class grid-cols-[repeat(auto-fill,minmax(14rem,1fr))] sets the grid to auto-fill columns with a minimum width of 14rem. The class gap-10 sets the spacing between grid items. The class bg-blue-100 sets a light blue background color.

Practice

1. What does implicit grid sizing do in Tailwind CSS grids?

easy

A. Automatically adds extra rows or columns when needed

B. Removes unused grid cells from the layout

C. Fixes the grid size to a specific number of rows and columns

D. Disables grid layout and switches to flexbox

Solution

1. Step 1: Understand grid behavior

   Implicit grid sizing means the grid can create extra rows or columns if content needs more space than defined.

2. Step 2: Recognize Tailwind usage

   Tailwind uses classes like grid-auto-rows-[size] to control these extra rows or columns.

3. Final Answer:

   Automatically adds extra rows or columns when needed -> Option A

4. Quick Check:

   Implicit grid sizing = auto-add rows/columns [OK]

Hint: Implicit means automatic extra rows/columns added [OK]

Common Mistakes:

• Thinking implicit sizing fixes grid size
• Confusing implicit sizing with removing grid cells
• Assuming implicit sizing disables grid

2. Which Tailwind class sets the size of implicit grid rows?

easy

A. grid-rows-[size]

B. grid-auto-rows-[size]

C. auto-grid-rows-[size]

D. grid-row-size-[size]

Solution

1. Step 1: Recall Tailwind naming conventions

   Tailwind uses grid-auto-rows-[size] to control implicit row sizes.

2. Step 2: Differentiate from similar classes

   grid-rows-[size] sets explicit rows, not implicit ones.

3. Final Answer:

   grid-auto-rows-[size] -> Option B

4. Quick Check:

   Implicit rows size = grid-auto-rows-[size] [OK]

Hint: Look for 'auto' in class for implicit sizing [OK]

Common Mistakes:

• Choosing grid-rows-[size] which is explicit sizing
• Using incorrect class names like auto-grid-rows-[size]
• Confusing row and column class names

3. Given this Tailwind grid container:

<div class="grid grid-cols-2 grid-auto-rows-16">
  <div>A</div>
  <div>B</div>
  <div>C</div>
</div>

What will be the height of the second grid row?

medium

A. 4rem

B. 16px

C. Default auto height

D. 16rem

Solution

1. Step 1: Understand the class grid-auto-rows-16

   This class sets implicit rows to 4rem because Tailwind's spacing scale '16' equals 4rem (64px).

2. Step 2: Identify the second row as implicit

   With 2 columns, the third item creates a new implicit row sized by grid-auto-rows-16.

3. Final Answer:

   4rem -> Option A

4. Quick Check:

   grid-auto-rows-16 = 4rem implicit row height [OK]

Hint: Tailwind spacing 16 = 4rem, implicit rows use grid-auto-rows [OK]

Common Mistakes:

• Assuming 16 means 16px instead of 4rem
• Thinking second row uses explicit row size
• Ignoring implicit row sizing

4. You wrote this Tailwind grid:

<div class="grid grid-cols-3 grid-auto-cols-20">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
</div>

But the extra column width is not applied. What is the likely mistake?

medium

A. grid-cols-3 conflicts with grid-auto-cols-20

B. Missing grid-auto-rows to set row height

C. Using grid-auto-cols-20 but no implicit columns are created

D. You must add auto-cols-auto to enable implicit columns

Solution

1. Step 1: Understand implicit columns

   Implicit columns only appear if content overflows the defined columns.

2. Step 2: Check grid setup

   With grid-cols-3 and 4 items, the 4th item creates a new implicit row, not column, so grid-auto-cols-20 is unused.

3. Final Answer:

   Using grid-auto-cols-20 but no implicit columns are created -> Option C

4. Quick Check:

   Implicit columns appear only if needed [OK]

Hint: Implicit columns appear only if content overflows columns [OK]

Common Mistakes:

• Confusing implicit rows with implicit columns
• Thinking grid-auto-cols sets explicit columns
• Adding unrelated classes like auto-cols-auto

5. You want a grid with 2 fixed columns and any extra items placed in new rows sized 6rem tall automatically. Which Tailwind classes achieve this?

hard

A. grid grid-cols-2 grid-rows-auto-[6rem]

B. grid grid-cols-2 grid-rows-[6rem]

C. grid grid-cols-2 grid-auto-cols-[6rem]

D. grid grid-cols-2 grid-auto-rows-[6rem]

Solution

1. Step 1: Set fixed columns

   grid-cols-2 fixes two columns as required.

2. Step 2: Set implicit row height

   grid-auto-rows-[6rem] sets the height of any automatically added rows to 6rem.

3. Step 3: Verify other options

   grid-rows-[6rem] sets explicit rows, not implicit. grid-auto-cols-[6rem] affects columns, not rows. grid-rows-auto-[6rem] is invalid syntax.

4. Final Answer:

   grid grid-cols-2 grid-auto-rows-[6rem] -> Option D

5. Quick Check:

   Implicit rows size = grid-auto-rows-[size] [OK]

Hint: Use grid-auto-rows-[size] for implicit row height [OK]

Common Mistakes:

• Using grid-rows-[size] instead of grid-auto-rows-[size]
• Confusing row and column classes
• Using invalid class syntax
