What this tool does

A visual CSS Grid layout designer for the kind of layouts you actually ship — 12-column hero rows, three-card product galleries, main + sidebar app shells, and the classic holy-grail (header / nav / main / aside / footer) page skeleton. Set the number of rows and columns, pick a gap value, then choose how columns should size: equal (1fr 1fr 1fr ...), fit-content (auto), or per-track custom values where every column gets its own size string (200px, minmax(0, 1fr), 12rem, 25%, anything CSS Grid accepts). Click a cell to give it a name — header, sidebar, content — and drag across cells to merge them into a single named area (grid-template-areas style). The preview panel renders the grid live using the exact same values that will end up in your copied CSS, so what you see is what you ship. Hit copy and paste display: grid; grid-template-columns: ...; grid-template-rows: ...; gap: ...; grid-template-areas: ...; into your stylesheet, your Tailwind arbitrary-value class, or a React inline style. Four presets get you started in one click; everything is editable from there. 100% client-side, no upload, no account, no tracking — designed for developers wiring layouts in React/Vue/Svelte, designers prototyping responsive grids before handing off, and indie builders who want the right grid in 60 seconds instead of 20 minutes of MDN deep dives.

How CSS Grid Generator fits into your work

Use it while choosing, checking, converting, or documenting colors for real interface work.

Color jobs

  • Moving from a visual idea to reusable color values.
  • Checking contrast and accessibility before a UI ships.
  • Keeping brand, design, and implementation color decisions aligned.

Color checks

  • Verify contrast against the actual background, not just a sample swatch.
  • Check dark and light themes separately when both exist.
  • Copy the final format your design system or codebase expects.

Real-world use cases

  • Building a holy-grail dashboard shell in React

    You need a header / nav / main / aside / footer layout for an admin panel. Name the cells, drag to merge the header across all 5 columns, set the sidebar to 240px and main to 1fr, then copy the grid-template-areas block straight into your layout component. What took 20 minutes of hand-counting line numbers now takes about 90 seconds, and the named areas read clearly in review.

  • Prototyping a responsive product gallery before handoff

    A designer wants 4 cards per row on desktop that reflow to 2, then 1 on phones. Set columns to repeat(auto-fit, minmax(240px, 1fr)) and a 24px gap, drop in placeholder cells, and watch the live preview reflow as you resize the panel. Copy the 3-line CSS and hand the developer a layout that needs zero media queries for the grid itself.

  • Pasting a grid into a Tailwind arbitrary-value class

    Your project uses Tailwind and you want a 280px sidebar plus a fluid content column without leaving utility classes. Set custom tracks to 280px 1fr, copy the generated grid-template-columns value, and wrap it as grid-cols-[280px_1fr]. The generator gives you the exact track string so you skip the trial-and-error of guessing fr units in the browser devtools.

  • Teaching a junior dev why their grid overflows

    A teammate's three-card row keeps blowing past the container because a long product URL forces a track to 600px. Rebuild the same grid here, flip the offending column from 1fr to minmax(0, 1fr), and show the preview snap back into place. It turns an abstract spec gotcha into a before/after they can see, copy, and remember.

Common pitfalls

  • Using 1fr everywhere and wondering why a column won't shrink — a track with long content needs minmax(0, 1fr), not 1fr, or its auto floor refuses to go below the content width.

  • Forgetting that grid-template-areas requires every cell to be named and each area to be a rectangle — leave gaps as "." and never make an L-shaped region, or the whole template silently fails.

  • Reaching for Grid on a one-dimensional row of buttons — if items only flow along one axis and wrap, Flexbox with flex-wrap is simpler than fighting grid track counts on every breakpoint.

Privacy

Everything runs in your browser. The rows, columns, gap, track sizes and area names you enter never leave the page — there is no upload, no account and no server call. When you turn on shareable links, your grid settings are encoded into the URL so a teammate opening it sees the same layout; keep that in mind before sharing a link publicly, since the parameters travel in the address bar. Nothing is stored or tracked otherwise.
