🎨 CSS Grid vs Flexbox — Which One Should You Use?

When building responsive and complex layouts, two powerful CSS tools come to mind: Flexbox and Grid. Both are essential, but they solve different problems. Let’s dive deep into their differences and understand when to use each.

🧩 What is Flexbox?

Flexbox (Flexible Box Layout) is a one-dimensional layout system, meaning it deals with either rows or columns at a time.

✅ Great for aligning elements in one direction
✅ Automatically adjusts item size to fill available space

📌 Example:

cssCopyEdit.container {
  display: flex;
  justify-content: center;
  align-items: center;
}

🧱 What is Grid?

CSS Grid Layout is a two-dimensional system, allowing you to control both rows and columns simultaneously.

✅ Ideal for complex layouts
✅ Makes building full-page layouts easier

📌 Example:

cssCopyEdit.container {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  grid-gap: 20px;
}
