Visually design CSS Grid layouts with flexible column/row sizing. Set gap, configure spanning cells, and export production-ready CSS and HTML.
Open CSS Grid Builder → free, no sign-inCSS Grid is the most powerful layout system the web has seen, but visualising a grid before writing the code is genuinely difficult — especially for complex layouts with spanning cells, named areas, and mixed unit tracks. The CSS Grid Builder gives you a visual editor: define your columns, rows, and gaps, drag cells to span them, and export the production-ready CSS and HTML when the layout looks right.
Developers prototyping complex page layouts, designers communicating grid specifications, or anyone who thinks in visual grids but has to express them in CSS.

What is an fr unit?
The fr (fractional) unit distributes available space proportionally. 1fr 2fr gives one column twice the width of the other.
How is grid different from flexbox?
Grid is two-dimensional (rows and columns simultaneously). Flexbox is one-dimensional (row or column). Use Grid for page layouts, Flexbox for component layouts.
What is grid-template-areas?
A way to name grid zones and assign elements to them by name — making complex layouts more readable.
Can I have cells span multiple columns?
Yes — grid-column-span and grid-row-span are configurable in the builder.
Does this generate responsive grid code?
The grid structure is generated — media queries for responsive breakpoints would need to be added manually.
