CSS Grid Layout
CSS Grid Layout is the most powerful layout system available in CSS. It is a 2-dimensional system, meaning it can handle both columns and rows, unlike Flexbox which is largely 1-dimensional.
Core Concepts:
- Grid Container: The parent with
display: grid. - Grid Tracks: The rows and columns defined with
grid-template-rowsandgrid-template-columns. - Grid Areas: Rectangular spaces on the grid made of one or more cells.
- fr unit: A fractional unit representing a fraction of the available space.
Examples
Valid - 3-Column Layout
display: grid;
grid-template-columns: 1fr 1fr 1fr;
gap: 20px; Valid - Sidebar + Main
display: grid;
grid-template-columns: 250px 1fr;
gaps: 1rem; Valid - Auto-Fit Grid
display: grid;
grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));Frequently Asked Questions
What is the difference between auto-fill and auto-fit?
`auto-fill` fills the row with as many columns as it can, even if they are empty. `auto-fit` collapses empty columns and stretches the items to fit the row.
Can nested grids be subgrids?
Yes! `grid-template-columns: subgrid` allows a child to inherit the grid tracks of its parent, ensuring perfect alignment across nested components (supported in Firefox and Safari, coming to Chrome).
Grid vs Bootstrap?
CSS Grid replaces the need for layout frameworks like Bootstrap for structure. It is native, lighter, and more flexible.
💡 Tips
- Use `repeat(auto-fit, minmax(300px, 1fr))` for instantly responsive card grids without media queries.
- Name your grid lines for easier maintenance in complex layouts: `[main-start] 1fr [main-end]`.
