3 <div style="height:100px;background-color:yellow">
4 <div style="float:left;height:500px;background-color:green">Hello world</div>
6 <div style="overflow:hidden; height:100px; border:2px solid black">Does the float intrude?
7 <span style="float:right;width:100px;background-color:purple;height:400px"></span>
9 <div>This text should not overlap the purple float? Will this happen? I'm really not sure.
