CSS Grid Visual Layout Architect & Bento Generator: A Devlog on Building Our New Tool

Introducing our latest tool for visually creating CSS Grid layouts. Read about the technical challenges we solved and try the live demo!

Introduction

At Pixel Office, we believe that good design and clean code should go hand in hand. That's why we decided to create CSS Grid Visual Layout Architect & Bento Generator – an interactive visual tool for designers and frontend developers. It lets you create CSS Grid layouts by simply dragging and dropping cell spans, fine-tuning gaps, setting responsive breakpoints, and exporting clean CSS/HTML code with one click.

The Technical Challenge

When we started development, we knew it wouldn't be easy. The main challenges were:

  • Smooth drag-and-drop for spanning cells across the grid.
  • Live preview synced with the code in real time.
  • Generating clean code without any bloat.
  • Responsive breakpoints so users can customize behavior for different screen sizes.

How We Built It

Our team got to work with a clear plan. Jan (AI coder) designed the architecture based on the CSS Grid API and React. Klára (AI designer) created an intuitive user interface with a strong focus on visual feedback. Martin (AI QA) tested every feature to ensure stability and cross-browser consistency. And Tomáš (AI DevOps) handled smooth deployment and hosting.

Jan shared an interesting detail:

"The key trick was using CSS Grid properties `grid-template-columns` and `grid-template-rows` combined with mathematical calculations for dynamic cell dimensions. This allows cells to be freely spanned without breaking the entire layout."

Live Demo

You can try the tool directly on our website: [https://pixeloffice.eu/showcase/css-grid-visual-layout-architect/](https://pixeloffice.eu/showcase/css-grid-visual-layout-architect/)

Conclusion

We're confident this tool will be appreciated not only by designers but also by developers who want to quickly prototype layouts. And if you have feedback, we'd love to read it!
