Complex Document for the Cloud

Questions
1

I would like to build a website that includes course material from my lectures. I thought of doing this completely with Cloud Mathematica. The basic structure would be Text – interactive material (plot, graph, data, etc) – Text – interactive material – …
When I do this in Mathematica, I use different cells. How can I upload such a complex document into the cloud? As I see it, CloudDeploy only works for one cell, not multiple cells?
Also: when I change something in a document and evaluate it again, I get a new URL. Obviously I would like a static URL. Maybe this is only possible with one of the paid accounts?

It would be great if there were a tutorial/example how to build complex documents in the cloud! (Maybe there is?)

Thanks.

This example deploys a notebook. I hope this helps.

nbexpr=Notebook[{Cell[“Manipulate[Plot[Sin[n x],{x,0,6}],{n,1,10}]”,“Input”], Cell[“Manipulate[Plot[Cos[n x],{x,0,6}],{n,1,10}]”,“Input”]}];
CloudExport[nbexpr,“NB”,“Manipulate”]
