A simple but really useful browser extension for frontend devs
Source: Dev.to

Overview
Co Designer is a Chrome extension that turns your browser into a visual CSS editor and generates ready‑to‑paste GitHub Copilot CLI prompts from your changes.
- Select any element on a page.
- Tweak fonts, colors, layout, shadows visually.
- Hit “Generate” to receive a text prompt.
- Paste the prompt into GitHub Copilot CLI and apply the changes.
I used GitHub Copilot from start to finish on this project, and it was an amazing experience! 🥰
