How to Use the CSS Grid Generator
CSS Grid is the most powerful layout tool in modern CSS, enabling two-dimensional control over both rows and columns at once. Writing grid-template-columns and grid-template-rows by hand requires memorizing units like fr, minmax(), and auto-fit. This free CSS grid generator gives you visual controls and a live preview so you can build any grid layout in seconds.
Step 1: Set Columns and Rows
Use the Columns slider (1–12) and Rows slider (1–6) to define your grid dimensions. The live preview grid updates immediately to show how many cells your layout will have. For a 3-column 2-row layout, set columns to 3 and rows to 2 — you get 6 grid cells.
Step 2: Configure Gap Spacing
The Column Gap and Row Gap sliders set the spacing between grid cells in pixels. A gap of 16px is standard for most card layouts. The gap property only applies between cells — not to the outer edges of the grid container.
Step 3: Choose Column Sizing
Select from three column template modes. Equal fr units divides available space equally using repeat(n, 1fr). Auto-fit generates a responsive grid where columns adjust count based on viewport width. Custom lets you type any values like 300px 1fr 2fr for precise control.
Step 4: Use Layout Presets
Click any preset to instantly load a named layout: Holy Grail (classic 3-column layout with header and footer), Dashboard (mixed-size panels), Photo Gallery (auto-fit responsive grid), Blog Layout (content plus sidebar), or Sidebar+Content (60/40 split). Each preset sets columns, rows, gaps, and template values.
Step 5: Copy CSS and HTML
Click Copy CSS to copy the complete container styles including display: grid, grid-template-columns, grid-template-rows, and gap. Click Copy HTML to copy the matching markup with the correct number of child divs. Both outputs are production-ready for any modern browser.
FAQ
Is this CSS grid generator free?
Yes, completely free with no limits or account required. All grid building and previewing runs locally in your browser — no data is sent to any server.
What is CSS Grid?
CSS Grid is a two-dimensional layout system built into CSS. It lets you arrange elements into rows and columns simultaneously, making it ideal for full-page layouts, dashboards, photo galleries, and any design requiring precise placement across both axes.
What is the difference between CSS Grid and Flexbox?
CSS Grid is designed for two-dimensional layouts (rows AND columns simultaneously). Flexbox is designed for one-dimensional layouts (either row OR column). Use Grid for overall page structure and complex layouts; use Flexbox for aligning items within a single row or column.
What does the fr unit mean in CSS Grid?
The fr (fractional) unit represents a fraction of the available space in the grid container. For example, in a 3-column grid with 1fr 2fr 1fr, the middle column gets twice the space of each side column. It is the most flexible and responsive unit for grid sizing.
How do I make a responsive grid that changes columns?
Use grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)). This creates as many columns as will fit in the container, each at least 200px wide. The grid automatically adjusts the column count as the viewport resizes — no media queries needed.
What is grid-gap or gap in CSS Grid?
The gap property (formerly grid-gap) sets the spacing between grid cells. It accepts one value for both row and column gaps, or two values to set them separately: gap: row-gap column-gap. The gap only applies between cells, not on the outer edges of the grid.
How do I make a grid item span multiple columns?
Use grid-column: span N to make an item span N columns, or grid-column: start / end to specify exact placement. Similarly, grid-row: span N spans multiple rows. These are essential for headers, heroes, and sidebar layouts.
How do I copy the generated CSS and HTML?
Click Copy CSS to copy the complete grid container CSS, or Copy HTML to copy the HTML markup with correctly structured grid items. Paste them directly into your project — the code is production-ready.
