CSS Grid & Flexbox Layout Generator

Build a CSS Grid or Flexbox layout visually — set the number of columns and the gap between items, watch the preview update live, then copy the exact display: grid / display: flex CSS or the equivalent Tailwind layout utility classes.

How to use the CSS Grid & Flexbox Layout Generator

  1. Choose Grid or Flexbox. Pick which layout model to generate CSS for.
  2. Set the number of columns. Control how many columns the grid or flex-wrap layout uses.
  3. Adjust the gap. Set the spacing between items with the gap slider.
  4. Copy the CSS or Tailwind classes. Copy the generated display/grid-template-columns/gap CSS, or switch to the equivalent Tailwind classes.

Frequently asked questions

How do I create a CSS Grid layout?

Set display: grid and grid-template-columns (e.g. repeat(3, 1fr)) on the container, plus an optional gap. This generator builds that CSS from a columns slider with a live preview.

How do I create a Flexbox layout in CSS?

Set display: flex on the container along with flex-wrap and gap. This generator produces the equivalent Flexbox CSS alongside the Grid option.

What is the difference between CSS Grid and Flexbox?

Grid is two-dimensional (rows and columns at once) and best for overall page/section layout; Flexbox is one-dimensional (a single row or column) and best for aligning items within a component.

How do I control the gap between grid or flex items?

The CSS gap property sets spacing between items in both Grid and Flexbox without needing manual margins. Adjust it with the gap slider here.

How many columns should a responsive grid use?

A common pattern is 1 column on mobile, 2–3 on tablet, and 3–4+ on desktop — combine this generator’s output with a media query or CSS auto-fit/minmax() for full responsiveness.

Can I export the layout as Tailwind classes?

Yes. Toggle Tailwind mode to get the equivalent grid-cols-*/flex/gap-* utility classes instead of raw CSS.

Is this CSS layout generator free?

Yes — completely free with no sign-up, and it runs entirely in your browser.

Does it support a dark mode preview?

Yes, toggle the light/dark preview to check spacing and contrast in both themes.
