making showcase go across the page instead of down the side

Hi,

I need for my widgets to go across the page instead of down. I need to add images to it also. Here is what my site is supposed to look like:https://redneckproperty.com/
But here is what it does look like. Obviously I’m having many issues, but if someone could help me with the widget areas first, that would be great. Here is my site:

thanks for any advice you can give me.

Cristi
