There are also plenty of existing tools for turning Photoshop mockups into HTML/CSS using hard coded assumptions about HTML structure and appropriate ways to slice images, with tradeoffs involving clunkier code, lack of intelligent support for other devices and window sizes and inability to change the shade of aqua at 3am unless you have a basic idea of how the output is structured.

From what I can see the Deep Learning process tried here needs a lot more technical knowledge to create a suitable training set for the type of output you want, a lot of iterations to converge on anything vaguely suitable, and even when it gets to what's considered an end product you're likely going to have to dive into the output code to correct button colours and text before we even start to think about its behaviour at different window sizes. As an experiment it's very interesting, as a replacement for the designer it's probably behind non-AI approaches to turning pics to code.
