Title: removed live sample iframe border

I liked the idea of having a visual separation to show live samples, but right now this would require more styling imo, this sample image illustrates what it gives on a live sample made this weekend for the mdn weekend Paris

padding would be nice, but would interfere with layout if the size is 100% (unless we use box-sizing: border-box), but this is only working since ie8.

I think we have a better look without it until we give it a proper appearance
