5. You want to create a responsive Vue component with Tailwind that shows a vertical stack of cards on small screens and a horizontal row on medium and larger screens. Which class combination on the container div achieves this?
hard
A. flex flex-col md:flex-row gap-4
B. grid grid-cols-1 md:grid-cols-3 gap-4
C. block md:flex-row flex-col gap-4
D. flex-row flex-col md:flex gap-4
Solution
Step 1: Understand responsive Tailwind classes
flex-col stacks items vertically; md:flex-row switches to horizontal row on medium screens and up.
Step 2: Check gap usage
gap-4 adds spacing between cards in both layouts.
Step 3: Evaluate options
flex flex-col md:flex-row gap-4 correctly uses flex with flex-col by default and md:flex-row for medium+ screens. Others misuse grid or class order.
Final Answer:
flex flex-col md:flex-row gap-4 -> Option A
Quick Check:
flex-col then md:flex-row creates responsive vertical to horizontal layout [OK]
Hint: Use flex-col then md:flex-row for responsive stack to row [OK]
Common Mistakes:
Using grid instead of flex for this layout
Wrong order of classes causing no effect
Missing responsive prefix md: on flex-row
