<!-- The container is split by the column-spans.
a) Before column-span1, it distributes 200px height into two columns,
and each column takes 100px height.
b) In between column-span1 and column-span2, same distribution as a).
c) After column-span2, it has 50px height left, which goes to the first
column.
