+/*******************************************************************************
+ * Navbar component

[juliandoucette, 2017/12/01 16:30:43]

I think that all paddings in this file should be separate (not website-default)
or optional / configurable (variable) because (at least) abp.org doesn't share
them.

We could also provide two examples of how-to space this component (parent space
/ help centre vs child space / abp.org).

(When you're free let's discuss how this would work)
