This is about style apps using CSS:

Similar to NUI https://github.com/tombenner/nui

I'm using it. Easier than UIAppearance, but still need some improvements in handling UICollection (it lags). However, overall is good.

I had the same issue. There was no clear indication of what this does.

Basically, it allows you to style your native iOS app with CSS like a website instead of using Apples native styling. For example I have this game and I can make a css file to create and/or change the color scheme of my app. Here is an example of some themes all generated from LESS css files[1].
