I have a big blank space from the last paragraph to the bottom of my site. I can't remove it, all the pages on my site are like this. Here is my site http://www.eventlogmonitoring.net/ how can I remove this big blank space?

Thanks

You're decklaring a height value in some of your CSS, eg

#tyjms3 {
	width:548px;
	float:right;
	height:1800px;	
	background-image:url(images/windows-event-logs.jpg);
	border-left: #293845 solid 1px;
}

remove the height: declaration

That was it thanks
