[RESOLVED] What is wrong with these codes?

I can't figure out what's wrong with my codes. It's supposed to be a div containing text, inside a grey div. But it doesn't work.
Anyone know why?

#content {
width:500px;
margin-left:10px;
float:left;
border:solid 1px #000000;
}

When you float an item, you pull it out of the document flow. So the parent div doesn't expand to hold it.

Thank you. I added a float to the parent div too, and that fixed it.
