What is a Tailwind Grid Generator?
A Tailwind grid generator is a visual builder for CSS Grid layouts expressed with Tailwind utility classes. Instead of remembering the exact utility names and counting columns by hand, you move sliders for columns, rows, and gap, watch a live preview update, and copy the finished HTML.
The container uses two core utilities: grid to enable the grid display and grid-cols- followed by the column count. Spacing between cells is set with a gap- utility. A three-column grid with a 4-unit gap is written as grid grid-cols-3 gap-4, and a gap of zero uses the special gap-0 class.
The rows slider does not add a grid-rows- class. Instead it controls how many cells are generated: the total number of cells is always columns multiplied by rows. That makes it easy to fill a grid with placeholder blocks for a quick layout mockup. Each cell is a flex container so its content is centered both horizontally and vertically.
Cells cycle through a twelve-color palette so neighbouring blocks are easy to tell apart, and you can optionally print the cell index as a number. The whole tool runs client-side and outputs copy-ready HTML markup.
Key Concepts
- grid grid-cols-N — the container class that enables grid display and sets the column count.
- gap-N — controls the spacing between cells; a gap of zero produces
gap-0. - Cells — one
divper position, totalling columns multiplied by rows. - Color cycle — twelve Tailwind background colors applied in order to distinguish cells.
- Cell numbers — optional labels showing each cell index from 1 to the total.
- Copy-ready HTML — the generated markup includes the container and every cell.
How to Use
- Set the number of columns — Drag the Columns slider between 1 and 12 to choose the grid width.
- Set the number of rows — Drag the Rows slider between 1 and 12 to control how many cells are generated.
- Adjust the gap — Move the Gap slider from 0 to 8; a value of 0 produces the
gap-0class. - Toggle cell numbers — Turn numbered labels on or off to see or hide the index in each cell.
- Copy the HTML — Copy the generated markup and paste the container and cells into your project.
Grid Settings Reference
| Control | Range | Default | Effect on output |
|---|---|---|---|
| Columns | 1 to 12 | 3 | grid-cols-N |
| Rows | 1 to 12 | 3 | Multiplies the number of cells only |
| Gap | 0 to 8 | 4 | gap-N, or gap-0 at zero |
| Cell numbers | On / Off | On | Prints the index 1 to total in each cell |
| Cell position | Background class | Cell position | Background class |
|---|---|---|---|
| 1 | bg-blue-500 | 7 | bg-indigo-500 |
| 2 | bg-green-500 | 8 | bg-teal-500 |
| 3 | bg-yellow-500 | 9 | bg-orange-500 |
| 4 | bg-red-500 | 10 | bg-cyan-500 |
| 5 | bg-purple-500 | 11 | bg-rose-500 |
| 6 | bg-pink-500 | 12 | bg-lime-500 |
Worked Examples
- Default settings — 3 columns, 3 rows, gap 4 produces
grid grid-cols-3 gap-4with 9 numbered cells. - Two by two — 2 columns, 2 rows, gap 0 produces
grid grid-cols-2 gap-0with 4 cells and no spacing. - Four across — 4 columns, 1 row, gap 8 produces
grid grid-cols-4 gap-8with 4 cells. - Single column list — 1 column, 3 rows, gap 4 produces
grid grid-cols-1 gap-4with 3 stacked cells. - Twelve column wall — 12 columns, 1 row produces
grid grid-cols-12 gap-4with 12 cells. - Numbers off — turning cell numbers off keeps the same grid classes but leaves every cell empty.
Tips and Common Mistakes
- The rows slider changes cell count, not a rows class — the generated container never includes
grid-rows-, onlygrid-cols-andgap-. - Zero gap is a special case — the tool emits
gap-0rather thangap-when the slider is at 0. - Columns times rows equals the cells — increasing either slider multiplies the markup, so large grids get long.
- Cell colors are decorative — replace the
bg-*-500classes with your own styling before shipping. - The counter wraps after twelve — the thirteenth cell reuses the first color in the cycle.
- Safelist dynamic classes — Tailwind scans source files, so make sure the color and grid classes you copy are present in your code.
Common Use Cases
Grid layouts are everywhere in modern interfaces. These are some of the practical ways this generator helps.
- Card galleries — mock up a responsive card grid before adding real content.
- Dashboards — lay out stat tiles and widgets with a predictable column count.
- Photo grids — build an image mosaic and swap the placeholder cells for images.
- Feature sections — arrange marketing features into tidy columns.
- Skeleton screens — generate a block grid to represent loading content.

grid-cols-andgap-values change a layout in real time.
Frequently Asked Questions
What is Tailwind Grid Generator?
It is a free online tool that builds Tailwind CSS grid layouts visually. You set columns, rows, and gap with sliders and copy the generated HTML markup.
How do I use Tailwind Grid Generator?
Drag the Columns, Rows, and Gap sliders, optionally toggle cell numbers, then copy the generated HTML. The preview and markup update instantly as you move the sliders.
Is my data sent to a server or stored?
No. All processing is performed locally in your browser using JavaScript. Your settings never leave your device and are not stored, logged, or shared with any third party.
Is this compatible with Tailwind CSS v3 and v4?
Yes. The generated classes such as grid, grid-cols-3, and gap-4 are core utilities that work in both Tailwind CSS v3 and v4.
Is this tool free to use?
Yes. This tool is completely free to use with no limitations, registration, or API key required. There are no usage caps, and you can use it as often as you need.
How many cells are generated?
The number of cells is the column count multiplied by the row count. For example, 3 columns and 4 rows generate 12 cells.
Why is there no grid-rows class in the output?
The rows slider controls how many cells are generated rather than adding a grid-rows utility. The container only ever uses grid, grid-cols-N, and gap-N.
What happens when the gap is zero?
A gap of zero produces the gap-0 class. Any value above zero produces gap-N, such as gap-1 or gap-8.
