How do you make a grid responsive with Tailwind CSS?

Use responsive prefixes like sm:grid-cols-1, md:grid-cols-2, lg:grid-cols-3 to change columns at different screen widths.

beginner

Why use semantic HTML elements inside cards?

Semantic elements like <article> and <section> help screen readers understand the content, improving accessibility.

What Tailwind utilities help add spacing between cards?

Use gap-* utilities like gap-4 to add consistent space between grid items.

Which Tailwind class sets a grid with three columns on large screens?

A grid-cols-lg-3

B grid-cols-3

C lg:grid-rows-3

D lg:grid-cols-3

The prefix lg: applies styles on large screens, and grid-cols-3 sets three columns.

What does the Tailwind class gap-6 do in a grid?

A Sets grid columns to 6

B Adds 1.5rem space between grid items

C Adds 6px padding inside grid items

D Removes gaps between grid items

gap-6 adds 1.5rem (24px) space between grid rows and columns.

Which HTML element is best for a card container to improve accessibility?

A <article>

B <div>

C <span>

D <section>

<article> is a semantic element representing a self-contained piece of content, ideal for cards.

How do you make a grid have 1 column on small screens and 4 columns on extra-large screens in Tailwind?

A sm:grid-cols-4 xl:grid-cols-1

B grid-cols-1 grid-cols-xl-4

C sm:grid-cols-1 xl:grid-cols-4

D grid-cols-sm-1 grid-cols-xl-4

Use responsive prefixes sm: and xl: to set columns for different screen sizes.

What is the main benefit of using CSS Grid for a card layout?

A It easily creates flexible rows and columns that adapt to screen size

B It only works on desktop screens

C It requires JavaScript to function

D It disables responsive design

CSS Grid allows easy creation of flexible, responsive layouts without extra scripts.

Practice

1. What does a responsive card grid do in a web page layout?

easy

A. It only works on desktop screens.

B. It fixes the number of columns regardless of screen size.

C. It hides cards on smaller screens.

D. It changes the number of columns based on screen size.

Solution

1. Step 1: Understand responsive design

   Responsive design means the layout adapts to different screen sizes.

2. Step 2: Role of a responsive card grid

   A responsive card grid changes how many columns show depending on screen width, so cards fit nicely on all devices.

3. Final Answer:

   It changes the number of columns based on screen size. -> Option D

4. Quick Check:

   Responsive grid = column count changes [OK]

Hint: Responsive means layout adapts to screen size [OK]

Common Mistakes:

• Thinking columns stay fixed on all screens
• Assuming cards get hidden instead of rearranged
• Believing responsiveness only applies to desktops

2. Which Tailwind class correctly sets a grid with 1 column by default and 3 columns on medium screens and above?

easy

A. grid grid-cols-3 md:grid-cols-3

B. grid-cols-3 md:grid-cols-1

C. grid grid-cols-1 md:grid-cols-3

D. grid md:grid-cols-3 grid-cols-3

Solution

1. Step 1: Understand Tailwind responsive prefixes

   Classes prefixed with md: apply at medium screen sizes and larger.

2. Step 2: Set default and medium screen columns

   Default is 1 column (grid-cols-1), and medium screens get 3 columns (md:grid-cols-3).

3. Final Answer:

   grid grid-cols-1 md:grid-cols-3 -> Option C

4. Quick Check:

   Default 1 col, md+ 3 cols = grid grid-cols-1 md:grid-cols-3 [OK]

Hint: Use mobile-first: default then md: for medium screens [OK]

Common Mistakes:

• Putting grid-cols-3 before md: prefix incorrectly
• Missing the base grid class
• Reversing default and md: column counts

3. Given this Tailwind code snippet, how many columns will display on a large screen?

<div class="grid grid-cols-1 sm:grid-cols-2 md:grid-cols-3 lg:grid-cols-4 gap-4">...</div>

medium

A. 4 columns

B. 2 columns

C. 3 columns

D. 1 column

Solution

1. Step 1: Identify screen size breakpoints

   Tailwind applies classes from smallest to largest: default, sm, md, lg.

2. Step 2: Check lg:grid-cols-4 on large screens

   On large screens, the lg:grid-cols-4 class sets 4 columns.

3. Final Answer:

   4 columns -> Option A

4. Quick Check:

   Large screen uses lg: prefix = 4 columns [OK]

Hint: Largest breakpoint prefix overrides smaller ones [OK]

Common Mistakes:

• Choosing default or smaller breakpoint columns
• Ignoring the lg: prefix effect
• Confusing gap with columns

4. What is wrong with this Tailwind grid code if the cards do not space out properly?

<div class="grid grid-cols-3 gap-2 p-4">...</div>

medium

A. Using gap-2 instead of gap-4 causes no spacing.

B. Missing responsive prefixes for different screen sizes.

C. Padding p-4 should be on each card, not the grid container.

D. grid-cols-3 is invalid without grid-rows.

Solution

1. Step 1: Check responsiveness

   The code sets 3 columns always, no responsive changes for smaller screens.

2. Step 2: Effect on spacing and layout

   Without responsive prefixes, cards may look cramped on small screens because columns don't adjust.

3. Final Answer:

   Missing responsive prefixes for different screen sizes. -> Option B

4. Quick Check:

   Responsive prefixes needed for proper spacing [OK]

Hint: Add responsive prefixes to adjust columns on all screens [OK]

Common Mistakes:

• Thinking gap-2 means no spacing
• Believing padding must be on cards only
• Assuming grid-rows is required with grid-cols

5. You want a responsive card grid that shows 1 column on small screens, 2 columns on medium, and 4 columns on large screens, with consistent spacing and shadow on each card. Which Tailwind setup is correct?

hard

A. Card

B. Card

C. Card

D. Card

Solution

1. Step 1: Check column counts and breakpoints

   Card

   uses mobile-first: 1 column default, 2 at md, 4 at lg, matching requirements.

2. Step 2: Verify spacing and shadow

   Card
   uses gap-6 for consistent spacing and shadow with padding on cards, which is correct.

3. Final Answer:

   <div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-4 gap-6 p-4"> <div class="shadow p-4">Card</div> </div> -> Option A

4. Quick Check:

   Correct breakpoints and spacing =
   Card
   [OK]

Hint: Mobile-first columns then md: and lg: prefixes for responsiveness [OK]

Common Mistakes:

• Reversing breakpoint order
• Using inconsistent gap or padding
• Missing shadow or applying it incorrectly
