🌍 Real World

Masonry grids are popular for photo galleries, portfolios, and product showcases on websites.

💼 Career

Knowing how to build responsive, visually appealing grids is a key skill for front-end web developers and UI designers.

1

Set up the HTML structure with images

Create a <div> container with the class masonry-grid. Inside it, add exactly 6 <img> tags with these src attributes: photo1.jpg, photo2.jpg, photo3.jpg, photo4.jpg, photo5.jpg, and photo6.jpg. Each image should have an alt attribute describing it as Photo 1, Photo 2, and so on.

Tailwind

Hint

Use a <div> with class masonry-grid and add 6 <img> tags inside with the exact src and alt values.

2

Add Tailwind CSS classes for columns and gap

Add Tailwind CSS classes to the masonry-grid <div> to create a 3-column layout with a gap of 1.5rem between items. Use the classes columns-3 and gap-6.

Tailwind

Hint

Add the classes columns-3 and gap-6 to the masonry-grid <div> to create columns and spacing.

3

Make images responsive and add rounded corners

Add Tailwind CSS classes to each <img> tag to make images take full width of their column and have rounded corners. Use the classes w-full and rounded-lg on each image.

Tailwind

Hint

Add class="w-full rounded-lg" to each <img> tag to make images fill their column width and have smooth corners.

4

Make the grid responsive with fewer columns on small screens

Update the masonry-grid <div> classes to have 1 column on small screens and 2 columns on medium screens. Use the Tailwind responsive classes sm:columns-1 and md:columns-2 along with the existing columns-3 and gap-6.

Tailwind

Hint

Add sm:columns-1 and md:columns-2 classes to the masonry-grid <div> to make the grid adapt on smaller screens.

Practice

1. What does the Tailwind class columns-3 do in a masonry-style grid layout?

easy

A. It sets the font size to 3 rem.

B. It creates 3 rows with equal height.

C. It adds 3 pixels of margin between grid items.

D. It splits the container into 3 vertical columns for items to flow into.

Solution

1. Step 1: Understand the columns-3 class

   This class divides the container into 3 vertical columns, allowing items to flow vertically like bricks in a wall.

2. Step 2: Differentiate from rows and spacing

   It does not create rows or set spacing or font size; those are controlled by other classes like gap- or text-.

3. Final Answer:

   It splits the container into 3 vertical columns for items to flow into. -> Option D

4. Quick Check:

   columns-3 means 3 vertical columns [OK]

Hint: Remember columns-3 means 3 vertical columns, not rows [OK]

Common Mistakes:

• Confusing columns with rows
• Thinking it sets spacing or font size
• Assuming it creates fixed-height rows

2. Which Tailwind class correctly adds horizontal and vertical gaps between items in a masonry grid?

easy

A. space-x-4

B. columns-4

C. gap-4

D. m-4

Solution

1. Step 1: Identify gap class usage

   The gap-4 class adds consistent horizontal and vertical spacing between grid items.

2. Step 2: Differentiate from other spacing classes

   space-x-4 adds only horizontal spacing between flex items, m-4 adds margin around an element, and columns-4 sets column count, not spacing.

3. Final Answer:

   gap-4 -> Option C

4. Quick Check:

   Use gap-4 for spacing in grids [OK]

Hint: Use gap-4 for both horizontal and vertical spacing [OK]

Common Mistakes:

• Using space-x-4 which only adds horizontal space
• Confusing margin (m-4) with gap
• Using columns-4 to add space instead of columns

3. Given this HTML snippet using Tailwind:

<div class="columns-2 gap-3">
  <div class="bg-blue-300 p-4">Item 1</div>
  <div class="bg-green-300 p-4">Item 2</div>
  <div class="bg-red-300 p-4">Item 3</div>
  <div class="bg-yellow-300 p-4">Item 4</div>
</div>

How will the items be arranged visually?

medium

A. Four horizontal rows with items side by side.

B. Two vertical columns with items flowing top to bottom in each column.

C. A single column with all items stacked vertically.

D. Items arranged in a 2x2 grid with equal height rows.

Solution

1. Step 1: Understand columns-2 effect

   The container is split into 2 vertical columns. Items flow vertically in each column, filling the first column top to bottom, then the second.

2. Step 2: Analyze gap and item styling

   The gap-3 adds spacing between columns and rows. Each item has padding and background color but no fixed height, so heights can vary.

3. Final Answer:

   Two vertical columns with items flowing top to bottom in each column. -> Option B

4. Quick Check:

   columns-2 means 2 vertical columns [OK]

Hint: Columns flow vertically, not horizontally [OK]

Common Mistakes:

• Thinking columns create rows
• Assuming equal height rows automatically
• Ignoring vertical flow in columns

4. You wrote this Tailwind code for a masonry grid:

<div class="columns-3 gap-4">
  <div class="p-4">Item A</div>
  <div class="p-4">Item B</div>
  <div class="p-4">Item C</div>
</div>

But the items appear stacked in one column instead of three. What is the likely cause?

medium

A. The container div is missing a width or max-width, so columns collapse.

B. The gap-4 class is invalid and breaks layout.

C. The items need flex class to arrange in columns.

D. Tailwind does not support columns-3 for masonry layouts.

Solution

1. Step 1: Check container sizing

   Without a set width or max-width, the container may shrink to fit content, causing columns to collapse into one.

2. Step 2: Verify other classes

   gap-4 is valid, and columns-3 works for masonry. Flex is not needed here because columns use CSS multi-column layout.

3. Final Answer:

   The container div is missing a width or max-width, so columns collapse. -> Option A

4. Quick Check:

   Container width needed for columns to show [OK]

Hint: Ensure container has width for columns to display [OK]

Common Mistakes:

• Assuming gap-4 breaks layout
• Adding flex unnecessarily
• Thinking Tailwind lacks columns support

5. You want a responsive masonry grid that shows 1 column on small screens, 2 columns on medium, and 4 columns on large screens using Tailwind. Which class combination achieves this?

hard

A. columns-1 md:columns-2 lg:columns-4 gap-6

B. grid grid-cols-1 md:grid-cols-2 lg:grid-cols-4 gap-6

C. flex flex-wrap gap-6 columns-4

D. columns-4 md:columns-2 lg:columns-1 gap-6

Solution

1. Step 1: Understand responsive columns classes

   Using columns-1 md:columns-2 lg:columns-4 sets the number of columns based on screen size: 1 for small, 2 for medium, 4 for large.

2. Step 2: Confirm gap usage

   gap-6 adds consistent spacing between items across all screen sizes.

3. Step 3: Differentiate from grid and flex

   Grid and flex layouts are different from masonry columns. grid grid-cols-1 md:grid-cols-2 lg:grid-cols-4 gap-6 uses grid, which is not masonry style. flex flex-wrap gap-6 columns-4 mixes flex and columns incorrectly. columns-4 md:columns-2 lg:columns-1 gap-6 reverses column counts.

4. Final Answer:

   columns-1 md:columns-2 lg:columns-4 gap-6 -> Option A

5. Quick Check:

   Responsive columns use breakpoint prefixes [OK]

Hint: Use responsive prefixes with columns-{n} for masonry grids [OK]

Common Mistakes:

• Using grid instead of columns for masonry
• Mixing flex with columns incorrectly
• Reversing responsive column counts
