Quick start

How to generate CSS Grid

Choose rows, columns and gap with a visual layout preview.

  1. Step 1
    Configure tracks

    Set your column and row count, then tune gap size.

  2. Step 2
    Check live grid

    Validate spacing and structure in the preview panel.

  3. Step 3
    Copy CSS

    Use the generated display/grid-template/gap declaration block.

In-depth guide

CSS Grid generator

Build responsive CSS grid layouts with live visual feedback and copy-ready CSS.

Grid mental model

Define tracks first (grid-template-columns and grid-template-rows), then place content. Gap controls spacing between tracks.

Responsive tip

Start with 1-2 columns on small screens and scale to 3-4 columns on desktop breakpoints.

How to use it

  1. Set the number of columns and rows, then choose track sizing (fixed px, flexible fr, or auto).
  2. Adjust the gap and watch cells reflow in the live preview.
  3. Copy the generated display: grid rule into your stylesheet and drop your items inside the container.

The fr unit splits free space proportionally, and repeat(auto-fit, minmax(200px, 1fr)) gives you a responsive grid with no media queries.

Pitfalls and privacy

Mixing fixed px tracks with fr tracks can overflow on small screens — prefer minmax() so columns shrink gracefully. Grid sizes the container, not the content, so long unbreakable words still overflow a cell unless you add min-width: 0 or overflow-wrap. The generated CSS is built entirely in your browser; nothing is uploaded.

When to use it vs alternatives

Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.

Frequently asked questions

Can this generate named grid areas?

This release focuses on columns, rows and gap. Area-template mode can be added in the next sprint.

Is this beginner-friendly?

Yes. The preview mirrors exactly what the generated CSS does, so you can learn grid visually.

Does it work on mobile?

Yes. The controls and preview are responsive and usable on small screens.

What does the fr unit do?

The fr unit distributes leftover space proportionally. Two columns of 1fr 2fr split the row so the second is twice as wide as the first.

How do I make a grid responsive without media queries?

Use repeat(auto-fit, minmax(200px, 1fr)) so columns wrap automatically based on available width.

Why does long text overflow a grid cell?

Grid tracks have a minimum content size by default. Add min-width: 0 (or overflow-wrap: anywhere) to the cell so long words can wrap.
