Fixed discrepancy in docs/variables.
Added a nested margin variable.

Allows for lists (ul & ol) to be given a top side margin that's independent from the side margin of nested list items. This comes in handy for setting the list flush with content while allowing for a hanging indent (position: outside) and indenting nested lists too.
Fixed margin issue in top bar.
