Changing margins on a Div doesn't take affect?

[lisa65q]

I'm trying to change my footers margin so that it expands to the width of the webpage, instead it still seems to be affect by the 50px of left/right margin I added to my \[code\]#content\[/code\] section. What property am I missing here so I can remove the affect of the content's margins on my footer section?Html\[code\]<div id="wrapper" /> <div id="header" /> <div id="mast"><img src="http://i1256.photobucket.com/albums/ii488/terafanb/guildwars2/26.png" height="99" width="774=" /></div> <div id="below-mast" /> <div id="left" class="column"><img src="http://i157.photobucket.com/albums/t60/Dragon_Aleph/fantasy_warrior_23022-800x600.jpg" height="297" width="226" border="0" alt="Crusader Army" /></div> <div id="center" class="column"><img src="http://i157.photobucket.com/albums/t60/Dragon_Aleph/fantasy_warrior_23022-800x600.jpg" height="297" width="400" border="0" alt="Crusader Army" /></div> <div id="right" class="column"><img src="http://i157.photobucket.com/albums/t60/Dragon_Aleph/fantasy_warrior_23022-800x600.jpg" height="297" width="139" border="0" alt="Crusader Army" /></div> <div></div> <div id="content" /> <p> <div class="Heading">Forward Exchange *</div> $500.00 - collected upon the closing of the Relinquished Property. $500.00 - collected upon closing of each Replacement Property purchased. * Special credits may apply - Call Us.<br /></br> <div id="we-pay"> <br /> <div class="Heading">We pay interest</div> </br> We provide full disclosure of the fees involved in the transaction in the Exchange Agreement.
