OK, so now there's a new wrinkle. The original problem I was having: Sticky Footer, but only sometimes. I have a scroll bar in my browser, and I can't seem to make the extra 70px margin go away...

So what am I missing here? Here's the site: http://www.erisdesigns.net/Stage/McCampbellInsurance/index.html
回答1:
Set #wrapper{margin-bottom:-70px;position:relative;} and remove padding-bottom.
Then add a <div class="spacer"></div> at the bottom of your wrapper and add .spacer{height:70px;clear:both;} to your css like so:
<div id="wrapper">
...
stuff here
...
<div class="spacer"></div>
</div>
<div id="footer">
<p>Footer content</p>
</div>
This is usually how I do it. It might not be exactly what you want but it might point you in the right direction.
