Two-D Precision
Control both axes simultaneously. Axonix Grid Architect handles complex spatial relationships that Flexbox can't reach.
Spanning Logic
Create Bento-grids, magazine layouts, and complex dashboards by spanning items across multiple tracks with ease.
Clean Syntax
Every line of CSS is optimized for size and performance. We use the most modern shorthand Grid syntax available today.
Built With Care
“The output uses the CSS Grid Level 1 specification: repeat(n, 1fr) track definitions on the container and grid-column / grid-row span rules on individual items. Every slider and input maps directly to a property in the generated syntax tree, and the same grid properties are applied live to the canvas so the preview and the code always match.”
Mastering CSS Grid Architect
Design CSS Grid layouts visually by setting columns, rows, gaps, and per-item spans against a live canvas, then copy the generated grid CSS. Includes bento-style presets for dashboards, hero sections, and magazine layouts.
- 1Set the Columns and Rows sliders to define the base track count of the matrix.
- 2Adjust the Gap slider to control the spacing between modules.
- 3Click Generate Item to add new modules to the canvas.
- 4Edit each module's column and row span in the Spatial Data panel.
- 5Watch the live blueprint update as spans reshape the layout.
- 6Copy the Syntax Tree CSS into your stylesheet to reuse the layout.
- Dynamic Matrix Engine: The canvas redraws instantly as columns, rows, and gaps change.
- Item Spanning: Per-item grid-column and grid-row span controls for asymmetric layouts.
- Preset Library: Standard 3x3, Complex Bento, Hero Dashboard, and Sidebars presets to start fast.
- Up to 24 Items: Enough modules to model real-world layouts without visual clutter.
- Shorthand CSS Output: Clean grid-template and span rules that paste straight into a stylesheet.
- Blueprint Overlays: Visual track guides show column and row boundaries while you work.

Real Ways People Use This
Dashboard Layouts
Prototype admin panels with sidebar, header, and content zones using explicit column spans.
Bento Grid Design
Build the mixed-size tile layouts popular in modern SaaS product pages and app home screens.
Magazine Layouts
Arrange articles and images across asymmetric rows with varying row spans.
Landing Page Sections
Test feature grids and pricing layouts visually before writing production CSS.
Learning CSS Grid
Experiment with tracks and spans to understand how placement works without guessing in a text editor.
- The generated CSS targets Grid Level 1; subgrid (Level 2) is not included.
- Span values above the track count will overflow into implicit tracks — keep each item's span within the current column and row counts.
- Responsive behavior still needs media queries; the playground outputs a fixed track layout.
- 1Verify each item's span values stay within the current column and row counts.
- 2Test the layout at narrower viewport widths to spot overflow before shipping.
- 3Paste the generated CSS into a test page and confirm the grid matches the canvas.
