Troubleshoot div that won't stretch

I have a web page that has several divs embedded and I'm having a problem when a table has too many rows; when it does, the containing div falls short and bottom ones are displayed on top of the background instead.

Any hints on how to troubleshoot this? I've tried开发者_如何转开发 setting several attributes to the different divs with no luck?

Just a few things to check:

• Float attributes
• opening <div>and closing </div> tags do not overlap with other tags:

Example of wrong way:

<tr>
<div>
</tr>
</div>

Also, post some code so we can see where we can help.

It could be that you've set height: 100% on the div, which would make it the height of the visible page. As Kyle said some more details would be helpful.

we certainly need to see the code.. my first idea is that (depending on weather you use float: or not), you need to clear: both a few places.
