Thank you for the example! Yes, that definitely looks good, but is still just a webpage. Also, it has pictures with bad resolution, and a latex table that has been rendered as an image for some strange reason. So as usual, it is not consistent in its quality, which is usually the problem.
To compare, open the accompanying PDF, which is also provided along with the webpage. It is of MUCH higher quality, which is partially due to the fact that layout is static.
Furthermore, the webpage doesn't support pagination. The problem is turning it into a book, and there doesn't seem to be a good standard that supports HTML+KATEX/MATHJAX properly. In theory there is no reason they shouldn't, as epub support javascript, but in practice it just doesn't work properly.
