----------------
-- Second bug --
----------------

-> Produce the bug:

Scroll down (via multi-touch or mouse wheel) AND move your pointer in the
screen center. Blue "link" box would appear because of:
.post:hover aside{opacity:1;-webkit-transition:opacity 0.1s linear;}


If you scroll down/up when an animation occure on the "blue "link" box", the
entire header will "jump",freeze (because he's in fixed positioning)

-> What I except:
The header wouldn't "jump".
