Site Issues in Responsive Mode

[brianking]

I see at least 3 issues

• Header navigation pushed the Mozilla link out of place. An ideal solution would be to have a hamburger menu
• Text starting 'Are you interested in other areas...' sits at the side, instead of underneath
• Blank section near the bottom

@comzeradd can you possibly help with this?

(3rd issue illustrated)

We should switch in classic collapse/hamburger UI for the mobile view in order to fit the navbar.

Work in progress yet, but I started addressing the responsive problems of the website.
