Visual CSS Inspector

I'm working with a friend on a website. He's a great product manager and desinger. He understand well usability and accessibility. While working on a product, I wanted him to be more autonomous on making css changes and improvement. I notice he learned by experimenting and copying what he saw on other website.

I created an inspector so he can easily see the props of css elements and classes. He can also upload the html and css of the project we are working on, edit it, see results and download the changes.

I've updated the file so you can directly access the editor. You can authenticate if you want to, but it is no longer require. I would love to hear about your experience
