CSS Grid

🌐 What is CSS Grid?

Picture a spreadsheet… but for your website layout.
CSS Grid is a two-dimensional layout system that lets you control rows + columns at the same time.
It’s like Flexbox’s older, more structured sibling — the one who shows up to office meetings with a neatly colour-coded planner.

With Grid, you can:

Place items exactly where you want
Create rows and columns in seconds
Build complex layouts that stay responsive
Stop fighting with floats, positions, or hacks from 2010 😭

🪄 Why Grid is goated:

Perfect for full page layouts
Rows + columns = ultimate control
Less CSS, more power
Cleaner than Flexbox for complex layouts
Makes you look like you know what you’re doing even when you don’t

🧱 Basic CSS Grid Syntax:

1. Turn on Grid-

This is how you activate the grid layout system on any container:

.container { display: grid; }

Boom. You're officially in Grid mode.

2.Define Columns-

You decide how many columns your layout needs:

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

First column: 200px
Middle: flexible
Last: 200px

3. Define Rows-

Same idea for rows:

grid-template-rows: 100px auto 50px;

4. Add Spacing Between Items-

Because nobody likes elements hugging too close:

gap: 20px; /* both row + column */ row-gap: 10px; /* only rows */ column-gap: 30px; /* only columns */

5. Place Items-

Tell an item where to sit:

.item1 { grid-column: 1 / 3; /* spans from column 1 to 3 */ grid-row: 1 / 2; }

6. Grid Areas (Optional but Fire)

Name your zones to keep layout clean:

grid-template-areas: "header header header" "sidebar content content" "footer footer footer";

Assign area:

.header { grid-area: header; }

7. Responsive Magic-

grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));

⚔️ CSS Grid vs Flexbox —

Both are powerful. Both are modern.
But they’re built for different missions — like two cousins who pull up with different skill sets.
