My first answer for the construction -Js

 After I will read about that but I think is that 

 

-->'.longWay ul'

Is wrong because -->  'ul.longWay'    is the way I write that I am talking about the ul that inside the tag I create a class for it that the name is 'longWay' that I could replace for '.longWay'. So the other is that --> '.longWay li' (in that I am not completely sure hereafter I will sure), means that li in child of ul, so when I write '.longWay ul' I am saying that longWay is parent of ul and not exactly the ul, and this is the mistake, the sons of longWay are li (list item).
