joncards on "[Theme: Responsive] Attempting to resize post width."

I am using the Responsive theme and enjoying it. However, I am trying to place two tables side by side within the post and having a hard time.
I've tried to adjust the following properties in a custom-child theme.

#container
{max-width: 2000px;}
#wrapper{
	padding: 0;
	margin: 0;
}
#visiting_stats
{position: absolute;
right: 0;
top: 130px;
}
.content-blog
{right: 0;}

Is there a designated div or area of the CSS that determines the post size? I expanded the entire post and have tried positioning the table but there is still a lot of white space.
Any help would be wonderful!
