What people use CSS Grid Generator for

  • Laying out a dashboard or gallery with named areas rather than nested divs.
  • Building a responsive card grid that reflows without media queries.
  • Producing a layout where items must align across both rows and columns.

CSS Grid Generator: limits and things worth knowing

  • The fr unit distributes leftover space after fixed tracks are placed, so 1fr 1fr and 50% 50% behave differently once there is a gap.
  • repeat(auto-fit, minmax(200px, 1fr)) gives a responsive grid with no media queries at all. auto-fill keeps empty tracks in the row; auto-fit collapses them — that single word is the difference between items stretching and items staying put.
  • A track sized 1fr will not shrink below its content by default, which is why long unbroken text can overflow a grid. minmax(0, 1fr) fixes it.
  • Grid handles two dimensions and flexbox handles one. A row of items that just needs spacing is a flexbox problem, not a grid one.

Is it private and secure?

Your privacy is built in. CSS Grid Generator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
