📌 What is CSS Grid?

CSS Grid is a powerful 2-dimensional layout system that allows developers to create complex, responsive web layouts with ease. Unlike Flexbox (which is 1-dimensional), Grid controls both rows and columns at the same time — making it perfect for full-page layouts, dashboards, galleries, and component structures.

💡 Why Use CSS Grid?

🧱 Basic Terminology in CSS Grid

1️⃣ Grid Container

The parent element that holds the grid layout. You define it using:

.container {
  display: grid;
}

2️⃣ Grid Items

All direct children of the grid container automatically become grid items.

3️⃣ Tracks (Rows & Columns)

Grid uses tracks to define layout structure:

.container {
  display: grid;
  grid-template-columns: 200px 1fr 200px;
  grid-template-rows: 100px 200px;
}

🧩 A Simple Example

Let’s create a basic 3-column grid layout:

.grid {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  gap: 20px;
}

.item {
  background: lightblue;
  padding: 20px;
  border-radius: 8px;
}

📐 Important Grid Units

📲 Responsive Grid Example

Using repeat() and minmax() makes grids responsive without media queries:

.gallery {
  display: grid;
  gap: 20px;
  grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
}
