Between 991px and 768px, the header grows in size, but the content remains a fixed distance from the top, this results in about 10px being cutoff from the tutorial content and table of contents, see screenshot.

I would change the margin top of the content container to 150px and since the table of contents is position:fixed I would move it down to top:150px, however I did not want to introduce a new media query into docs.css.
