Learning ddoc

[Antonio Corbi via Digitalmars-d-learn]

Hi,

I'm in the process of learning how ddoc works.
I've successfully created docs for my code and recently learned 
how to generate it using dub.

Related to this and after seeing the announcement of the new 
release of the emsi-containers library, I had a look at its docs 
(http://economicmodeling.github.io/containers/index.html) but 
when I cloned the repo and generated it locally its appearance is 
completely different (no side-bar, different formatting for code 
examples, etc...), it's simpler, it must lack some css or 
whatever.

My question is...is there some standard way to generate 
better-looking doc-pages with ddoc?

Thanks!
Antonio
