CSS Grid Generator
Build responsive grid layouts faster: choose fixed columns or auto-fit minmax, set gap and row rules, preview instantly, then copy ready CSS and HTML.
How to Use the CSS Grid Generator
- Choose a layout mode: Fixed Columns or Auto-fit (minmax).
- Enter your columns or minimum column width, then set the gap size.
- Optionally set row height and choose item alignment settings.
- Click “Generate CSS” to view the code and live preview.
- Copy the CSS and HTML snippets and paste them into your page or component.

Formula / How It Works
CSS Grid is declarative: you describe the columns, spacing, and row behavior, and the browser calculates the final layout. This generator focuses on the most reliable patterns used in production UI.
Fixed Columns pattern
display: grid; grid-template-columns: repeat(N, minmax(0, 1fr)); gap: Gpx;
Auto-fit (minmax) pattern
display: grid; grid-template-columns: repeat(auto-fit, minmax(Mpx, 1fr)); gap: Gpx;
Variables: N = number of columns, M = minimum column width in pixels, G = grid gap in pixels. If you set a row height, the tool adds grid-auto-rows to make rows consistent; otherwise rows remain automatic based on content.
Practical Examples
🇮🇳 Mumbai, Maharashtra — Product card grid for a small store
Scenario: You want a responsive product listing that shows more columns on wider screens and fewer on mobiles.
Settings: Auto-fit, minimum width 260px, gap 16px.
Verified result: grid-template-columns: repeat(auto-fit, minmax(260px, 1fr)); gap: 16px;
🇮🇳 Bengaluru, Karnataka — 3-column dashboard widgets
Scenario: Your admin dashboard should always have exactly 3 columns on desktop, with equal widths.
Settings: Fixed columns 3, gap 20px, row height blank (auto).
Verified result: grid-template-columns: repeat(3, minmax(0, 1fr)); gap: 20px;
🇮🇳 Kolkata, West Bengal — Uniform tiles for a photo gallery
Scenario: You want equal-height tiles so the gallery feels consistent even when captions vary.
Settings: Fixed columns 4, gap 12px, row height 180px.
Verified result: grid-auto-rows: 180px; grid-template-columns: repeat(4, minmax(0, 1fr));
🇺🇸 Austin, USA — Blog cards with centered content
Scenario: Card content should be centered inside each cell for a tidy editorial look.
Settings: Auto-fit, minimum width 320px, gap 24px, justify-items center, align-items center.
Verified result: justify-items: center; align-items: center; grid-template-columns: repeat(auto-fit, minmax(320px, 1fr));
What Is a CSS Grid Generator?
A CSS Grid generator is a helper that turns a few layout decisions—like column behavior, minimum card width, spacing, and row rules—into correct CSS you can paste into your site. Instead of trial-and-error with repeat() and minmax(), you pick the intent and let the code reflect it.
Here is what most people get wrong: they treat grid like a “set columns and forget it” system. In real projects, layout changes with screen width, content length, and component spacing. Using an auto-fit + minmax pattern keeps the design responsive without writing multiple breakpoints.
Use this tool when you want a grid that’s easy to maintain, easy to read, and predictable for both simple landing pages and complex UI screens.
Frequently Asked Questions
Is this tool free to use?
Yes. You can generate and copy CSS Grid code here without any sign-in.
What is the difference between Fixed Columns and Auto-fit (minmax)?
Fixed Columns keeps an exact number of columns (like 3 or 4) across breakpoints. Auto-fit with minmax lets the grid automatically wrap items into new rows based on available width, using your minimum column width as the constraint.
Why does the generator use minmax(0, 1fr) for fixed columns?
minmax(0, 1fr) prevents overflow issues when grid items contain long words or wide content. It tells the browser the column can shrink to 0 if needed, while still distributing space evenly.
What should I set as a good minimum column width for responsive cards?
A common starting point is 240–320px for product or blog cards. If your cards have larger images or longer titles, increase the minimum so the layout doesn’t feel cramped on tablets.
How is gap different from margin between cards?
gap is a grid property that creates consistent spacing between rows and columns inside the grid container. Margins are applied on each item and can create uneven edges and extra spacing at the container boundaries.
Can I create equal-height rows with this tool?
Yes. Set a fixed Row height to apply grid-auto-rows. If you keep Row height as auto, each row grows naturally based on its content.
Will the generated CSS Grid work in modern browsers?
Yes. CSS Grid is supported by all major modern browsers. If you must support very old browsers, consider a fallback layout using flexbox or a simpler column system.
Does this generate both CSS and HTML?
It provides a clean CSS snippet for the grid container and a simple HTML structure you can paste and adapt. You can replace the sample items with your real content and classes.
