so I've been working on custom child theme based on twenty-eleven (that's just for you Esmi)
and there's a weird effect that happens to my sidebar when I change the width of the window.
The sidebar disappears and the main text area becomes black (the colour of the sidebar)

Anyone got an idea of what might be causing it?
here's the css for my sidebar (I think)
margin: -30px 0 0 0;
padding: 10px 10px 100% 30px;
