I have found a little layout bug with the footer widgets on mobile (not on desktop). You can see it here: http://morgan.1er.free.fr/wordpress/
I have set 3 different widgets in the 3 different footer areas A, B et C.
On desktop, the layout displayed is fine.
On mobile (I have an iPhone 4S), there is not enough space between the end of a widget and the title of the widget just after.
Not a terrible bug but still
