Responsive CSS triggers cause scrolling issue.

[pixiesky]

Inside Chrome on linux if I load the site "full width" and then reduce the width down (which I like to do so I can have code examples just sat on the side) I am unable to scroll down as the side menu that has just be hidden pushes against my own efforts to read what's down there. If I reload with a short width then all is good - presumably the side menu isn't there in the first place. My guess would be: it should be display:none; rather than a display:hidden; somewhere.

Also, sorry I forgot to mention, this happening at: http://p5js.org/get-started/

Looks like expected issue https://github.com/processing/p5.js-website/blob/master/js/scroll.js

I can work on fixing it if nobody is already working on it.
