CSS Layout Coding Challenge in Action

Challenge: "Create a responsive card grid layout with equal height cards"

Interviewer: "Build a responsive card grid layout where cards have equal heights regardless of content length. It should be 3 columns on desktop, 2 on tablet, and 1 on mobile."

/* HTML Structure */ <div class="card-grid"> <div class="card"> <h3>Card Title 1</h3> <p>Short content</p> </div> <div class="card"> <h3>Card Title 2</h3> <p>Much longer content that spans multiple lines</p> </div> <div class="card"> <h3>Card Title 3</h3> <p>Medium length content</p> </div> </div>

CSS Layout Strategy:

This challenge tests multiple CSS concepts:

CSS Grid: Perfect for equal-height cards and responsive columns
Responsive Design: Media queries for different breakpoints
Card Layout: Consistent spacing and alignment
Equal Heights: Grid automatically handles this

Implementation Approach:

Use CSS Grid for the main container layout
Set up responsive columns with grid-template-columns
Add proper spacing with gap property
Style individual cards with consistent padding
Implement media queries for different screen sizes

/* Modern CSS Grid Solution */ .card-grid { display: grid; grid-template-columns: repeat(auto-fit, minmax(300px, 1fr)); gap: 1.5rem; padding: 1rem; max-width: 1200px; margin: 0 auto; } .card { background: white; border-radius: 8px; padding: 1.5rem; box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1); transition: transform 0.2s ease; /* Grid automatically handles equal heights */ } .card:hover { transform: translateY(-4px); box-shadow: 0 4px 20px rgba(0, 0, 0, 0.15); }

/* Responsive Design with Media Queries */ /* Desktop: 3 columns */ @media (min-width: 1024px) { .card-grid { grid-template-columns: repeat(3, 1fr); } } /* Tablet: 2 columns */ @media (min-width: 768px) and (max-width: 1023px) { .card-grid { grid-template-columns: repeat(2, 1fr); } } /* Mobile: 1 column */ @media (max-width: 767px) { .card-grid { grid-template-columns: 1fr; padding: 0.5rem; } .card { padding: 1rem; } }

📱 Responsive Layout Preview

Card 1
Short

Card 2
Much longer content

Card 3
Medium

✨ All cards have equal height automatically

Alternative Solutions & Advanced Techniques:

1. Flexbox Alternative (if Grid not preferred):

.card-grid-flex { display: flex; flex-wrap: wrap; gap: 1.5rem; } .card-flex { flex: 1 1 calc(33.333% - 1rem); min-width: 300px; }

2. Container Queries (Modern Approach):

.card-grid { container-type: inline-size; } @container (min-width: 600px) { .card-grid { grid-template-columns: repeat(2, 1fr); } }

Key CSS Concepts Demonstrated:

✅ CSS Grid mastery: Automatic equal heights and flexible columns
✅ Responsive design: Mobile-first approach with breakpoints
✅ Modern CSS: Gap property instead of margins
✅ Performance: Hardware-accelerated transforms for hover effects
✅ Accessibility: Proper focus states and semantic structure

Follow-up Interview Questions:

"How would you add a sticky header to this layout?"
"Implement infinite scroll for the card grid"
"Add CSS animations for card loading states"
"How would you optimize this for performance?"
"Make the cards draggable and reorderable"
