Reposition GitHub and Awwwards Ribbons

#245 reports that the GitHub ribbon overlaps the navicon rendering it unclickable.

Analysis of the code shows that there is a top rule of 0px for viewports greater than 1024px, which causes this problem. Analysis of the code also shows that for viewports less than 1024px, a top rule is applied which prevents this problem. Removing this media query and applying the top rule to the first occurrence (on Line 3117) solves this problem.

The Awwwards ribbon will also be repositioned to accommodate this change.
