The situation is:
HTML:
<div id="main">
<div id="a"></div>
<div id="b">Some Text</div>
</div>
CSS:
#a{
float:left;
width:800px;
height:150px;
background-color:#CCC;
}
#b{
width:1000px;
height:100px;
background-color:#9CC;
}
The result:

Why doesn’t the text go behind div#a ? Why does “Some Text” behave as if div#a is still in the normal flow? How to force the text to act as expected (to go under div#a) ?
UPDATE:
When I mean under, I mean beneath on the Z axis, not on the Y. The div’s should stay in this position, the only part that needs moving is the text.

positionNote: to keep
#apositioned to it’s parent, rather than<body>:
