# CSS On The ESP32

**[Hackaday](https://daily.dev/sources/hackaday)** · 2 min read · 3 upvotes · 0 comments

## Summary

The Gea stack enables developers to write CSS and TypeScript for ESP32 microcontrollers, compiling it into native C++ firmware. A demo shows a smooth 3D cube animation running at up to 60 FPS on a 410×502 AMOLED screen with full color and transparency support. It's not a full browser engine — limitations include no hover states, rasterized fonts, and a 512-node UI tree cap — but it lets web developers leverage familiar skills for embedded UI development without major performance loss.

## Questions this post answers

### Can you use CSS to build a UI for an ESP32 microcontroller?

Yes, a toolchain called the Gea stack compiles CSS and TypeScript code into generated C++ that builds into native ESP32 firmware. It was demoed running a full-color 3D cube animation at up to 60 FPS on a 410x502 AMOLED screen, including transparent cube faces, though transparency comes with a performance cost.

_Developers bringing web skills to embedded UI work can find tools like this surfaced on daily.dev._

### What limitations does the Gea stack have compared to a full browser engine for ESP32 development?

It is not a full browser engine: it does not support ':hover' states since it's built for touchscreen interfaces, fonts are rasterized rather than rendered with a full text engine, and the UI tree is limited to 512 nodes. Despite these constraints, it runs smoothly on ESP32 hardware without major performance loss.

_Anyone evaluating embedded UI frameworks can track tradeoffs like these through daily.dev._
