I could not see what the exact issue was. Looks similar like the demo site. A screenshot which points to the actual issue will help. I am not sure you want to go the boxed way to handle this.
BTW, if you find the the items going really wide full screen (as in home page), pls wrap your HTML inside [segment] shortcode. There are plenty of examples of the use of shortcode in the import sample-data.xml file.
