Mastering CSS Grid Layout

# Mastering CSS Grid Layout

CSS Grid is a powerful layout system for creating complex, responsive designs.

## Basic Grid

Create a simple grid:

```css
.container {
display: grid;
grid-template-columns: repeat(3, 1fr);
gap: 1rem;
}
```

## Named Grid Areas

Define layout regions:

```css
.container {
display: grid;
grid-template-areas:
"header header header"
"sidebar main main"
"footer footer footer";
grid-template-columns: 200px 1fr 1fr;
gap: 1rem;
}

.header { grid-area: header; }
.sidebar { grid-area: sidebar; }
.main { grid-area: main; }
.footer { grid-area: footer; }
```

## Responsive Grid

Mobile-first responsive design:

```css
.grid {
display: grid;
grid-template-columns: 1fr;
gap: 1rem;
}

@media (min-width: 768px) {
.grid {
grid-template-columns: repeat(2, 1fr);
}
}

@media (min-width: 1024px) {
.grid {
grid-template-columns: repeat(3, 1fr);
}
}
```
