It seems from their github profile active development is going on in MUI CSS since Feb, 2015. This CSS framework looks decent. They given some pre-defined layout to start with. Also, first time I seen they given some example for HTML Email template.

They supports React, Angular JS and Web Components. Website is very neat and clean, it's a real pleasure to navigate their site.

I created a simple and short video overview (no installation, or tutorials) https://www.youtube.com/watch?v=8I2YS7OCkpQ
