"float: left" element with clearfix applied.

Hello this is the intro div. The content with of this box is 920 pixels. The actual width is 940 pixels because we have applied a 10 pixel padding to the box. Not very intuative is it for a thickie Graphic Designer. It gets worse, Microsoft decided it was so unintuative it decided to implement it the 'intuative' way, thus producing two ways in which the box model is implemented. It gets worse, IE has various quirks when rendering floated elements ( that's just about any page layout ). The double margin bug is the worst of these.
Main content goes here. I would suggest a quick intro to your proposition. What are you selling and why should your users buy it. Short bullet points work well and increasingly a video.
Ads normally go here.
