Github pages css troubles only on smartphone
I am creating a website using Jekyll, and publishing it using Github pages. When I jekyll serve the website in local, everything works fine, and it looks normal both from my computer and smartphone. But when I visit the Github pages one from my smartphone, some divs seem to be shifted a bit, and the font-awesome icons are not rendered. Strangely, it works fine when I visit it (the Github pages one) from my computer.
I am not sure where to look at. Could something happen on github and be overriding only some media queries?
I have no idea yet what is relevant in the code, but I'll try to create some MCV example. Until then, the source code is here and the website is here.
Here's the CSS, mostly taken from a Pure css layout:
* {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;

/*

EDIT: Here are a few pictures to explain what I mean.
From the Android default browser (which doesn't support CSS3 transitions and transforms, it seems): (OK)
From Firefox on Android: (NO HEADER, WEIRD BLUE BAR: NOT OK)
From my desktop's Firefox (resized to match a phone's dimension): (OK)
What's surprising is that it seems to only occur on firefox on Android. I also tried on an iPhone, and the result is as expected. Why that only happens from Github-pages and not from my local server is what startles me the most.
EDIT 2:
I just compared the css produced by Github Pages and the css produced by my server, and besides a few linebreaks and spaces here and there, they are identical. Could the difference reside in the HTML?
I've just reproduced this on Firefox 38 on Ubuntu.
While trying to find a box-model problem I saw this in my Firefox security console :
Blocked loading mixed active content "http://yui.yahooapis.com/pure/0.6.0/pure-min.css"[Learn More] nicowcow.github.io
Blocked loading mixed active content "http://yui.yahooapis.com/pure/0.6.0/grids-responsive-min.css"[Learn More] nicowcow.github.io
Blocked loading mixed active content "http://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css"[Learn More]
Then the problem might be here (see MDN documentation about MixedContent).
So, the solution is to request those three ressources over https.
This does work for Font-awesome at https://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css but not for pure files (NET::ERR_CERT_COMMON_NAME_INVALID).
You will have to host them on your server or find another provider which serve over htpps.
