CSS Grid provides a flexible two-dimensional layout system for modern web design.
1. Defining a Grid
.container {
display: grid;
grid-template-columns: repeat(3, 1fr);
grid-gap: 20px;
}
2. Grid Items
Items can span multiple columns or rows using grid-column and grid-row.
3. Auto Placement
The browser can automatically place items efficiently in the grid.
Conclusion
CSS Grid simplifies complex layouts compared to floats or flexbox alone.

Grid changed my life as a frontend dev! Cleaner than flexbox for complex layouts.
