javascript - Why is the inclusion of this js affecting the nested divs in my jade layout? -

I am creating an html page for node.js using Z. It works as if I want it, but if I want to delete the fifth row with the Javascript source space - then the shell divi is no longer nested inside the material cover but it is at the same level

this Why is that? It really is confusing to me and yes, you are right - I really do not know what I am doing! Layout (id = "true", resize = "true", keeps = "true") div (id = "sphere") // script (src = ' /javascripts/draw.js') div (id = "demo") | JQuery does not exist To work for the demo you have to install jQuery in this folder. Label (for = "color") div (id = "") div (class = "form-item", id = "color", name = "color", value = "# 123456") div (id = "picker ")
