Practice

1. Why is CSS Grid especially good for complex layouts compared to older methods like floats?

easy

A. It only works for single-column layouts.

B. It requires writing lots of extra CSS code.

C. It lets you place items in rows and columns easily without extra markup.

D. It only works on mobile devices.

Solution

1. Step 1: Understand CSS Grid's layout method

   CSS Grid allows placing items in rows and columns directly, unlike floats which need hacks.

2. Step 2: Compare with older methods

   Floats require extra wrappers and clearing, making complex layouts hard and messy.

3. Final Answer:

   It lets you place items in rows and columns easily without extra markup. -> Option C

4. Quick Check:

   Grid simplifies layout by rows and columns [OK]

Hint: Grid = easy rows and columns, no extra wrappers needed [OK]

Common Mistakes:

• Thinking Grid only works for simple layouts
• Confusing Grid with Flexbox for single direction
• Believing Grid needs lots of extra CSS

2. Which Tailwind class sets a grid with three equal columns?

easy

A. grid-cols-3

B. grid-rows-3

C. grid-gap-3

D. grid-flow-col

Solution

1. Step 1: Identify the class for columns

   In Tailwind, grid-cols-3 sets the grid to have 3 columns.

2. Step 2: Check other options

   grid-rows-3 sets rows, grid-gap-3 sets spacing, grid-flow-col changes flow direction.

3. Final Answer:

   grid-cols-3 -> Option A

4. Quick Check:

   3 columns = grid-cols-3 [OK]

Hint: Cols = columns, rows = rows in class names [OK]

Common Mistakes:

• Confusing rows and columns classes
• Using gap class to set columns
• Mixing flow direction with column count

3. What will be the visual layout result of this Tailwind code?

<div class="grid grid-cols-2 gap-4">
  <div>A</div>
  <div>B</div>
  <div>C</div>
</div>

medium

A. Two columns with A and B in first row, C alone in second row

B. Three columns in one row with A, B, C

C. One column with A, B, C stacked vertically

D. Grid with no gaps and all items overlapping

Solution

1. Step 1: Understand grid-cols-2 and gap-4

   The class grid-cols-2 creates 2 columns, and gap-4 adds space between items.

2. Step 2: Place items in grid

   Items fill rows left to right: A and B in first row, C starts second row alone.

3. Final Answer:

   Two columns with A and B in first row, C alone in second row -> Option A

4. Quick Check:

   2 columns + 3 items = 2 in first row, 1 in second [OK]

Hint: Items fill rows left to right in grid-cols-N [OK]

Common Mistakes:

• Assuming all items fit in one row
• Ignoring gap spacing effect
• Thinking grid-cols-2 means 3 columns

4. Identify the error in this Tailwind grid layout code:

<div class="grid grid-cols-3 gap-2">
  <div class="col-span-4">Item</div>
</div>

medium

A. gap-2 is not a valid Tailwind class

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

C. grid-cols-3 should be grid-rows-3

D. Missing closing tag for div

Solution

1. Step 1: Check grid column count

   The grid has 3 columns set by grid-cols-3.

2. Step 2: Validate col-span value

   col-span-4 tries to span 4 columns, which is more than available 3 columns, causing layout error.

3. Final Answer:

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

4. Quick Check:

   Span cannot exceed total columns [OK]

Hint: Span number must not exceed grid columns [OK]

Common Mistakes:

• Using col-span larger than columns
• Confusing gap class validity
• Misreading grid-cols as rows

5. You want a responsive layout with 4 columns on large screens and 2 columns on small screens using Tailwind. Which code correctly achieves this?

hard

A. ...

B. ...

C. ...

D. ...

Solution

1. Step 1: Understand responsive prefixes

   In Tailwind, lg: prefix applies styles on large screens and above.

2. Step 2: Check column classes for responsiveness

   grid-cols-2 sets 2 columns by default (small screens), lg:grid-cols-4 changes to 4 columns on large screens.

3. Final Answer:

   <div class="grid grid-cols-2 lg:grid-cols-4 gap-6">...</div> -> Option D

4. Quick Check:

   Default 2 cols, large screens 4 cols [OK]

Hint: Use lg: prefix for large screen overrides [OK]

Common Mistakes:

• Reversing small and large screen classes
• Missing grid class for display
• Using grid-rows instead of grid-cols
