I'm working on this website for my dad:http://smartcampusdeals.com/TendonAiD/index3.htmland the three columns (with the stick cartoony people) extend past the container. Right now, I have the container set at a static height (700px or something) but I want the height to adjust, so I don't have to change it for every other page. Why are these three columns behaving that way and what can I do to fix it? 
Clearing floats? Or something else?
