📖 What is CSS Grid Generator?
CSS Grid Generator creates grid layouts visually. Define columns, rows, gaps, alignment and named grid areas with a live preview. Copy the generated CSS for your project. Use it to prototype layouts, learn CSS Grid, or quickly build page structures without memorizing grid syntax. Everything runs in your browser.
💡 Example
Input
Columns: 1fr 1fr 1fr
Rows: auto auto
Gap: 16px
Output
display: grid;
grid-template-columns: 1fr 1fr 1fr;
grid-template-rows: auto auto;
gap: 16px;
🛠️ Common Use Cases
- Prototyping page layouts (header, sidebar, main, footer)
- Building responsive grid systems for cards and galleries
- Learning CSS Grid syntax with visual feedback
- Creating dashboard layouts with fixed and flexible sections
- Generating grid CSS for component libraries
📝 CSS Grid Properties
grid-template-columns — defines column sizes (px, fr, %, auto)grid-template-rows — defines row sizesgap — space between grid cellsgrid-template-areas — named layout regionsfr — fractional unit (1fr = 1 equal share of available space)repeat(3, 1fr) — shorthand for 1fr 1fr 1fr
⚠️ Common Mistakes
- Confusing Grid and Flexbox — Grid is 2D (rows + columns). Flexbox is 1D (one direction). Use Grid for page layout, Flexbox for component alignment.
- Not using fr units — fixed pixel columns break responsive design. Use fr for flexible columns.
- Forgetting gap — without gap, grid items touch edges. Gap replaces the need for margin hacks.
❓ Frequently Asked Questions
When should I use CSS Grid vs Flexbox? ▾
Use Grid for 2D layouts (rows AND columns together) like page structures. Use Flexbox for 1D layouts (alignment in one direction) like navbars or card rows.
What does fr mean? ▾
fr stands for "fraction." 1fr means one equal share of available space. Two columns of 1fr 2fr means the second column is twice as wide.
Can I make a responsive grid without media queries? ▾
Yes — use repeat(auto-fit, minmax(250px, 1fr)) to create a grid that automatically adjusts the number of columns based on available width.
