I want to change to the new twenty fourteen theme because it's a nice look and feel. However if I try so the content is reduced only on a small area and a lot of space on the page is unused.
I already tried this: how to create a conditional content_width for a wordpress theme? but it does not help me at all.
to give you an image of what i mean look at this: Unused pagearea marked in yellow
Some of you know where and what do I have to change to fit the whole area?
