I am working with an existing system, and am trying to modify the CSS in order to arrange the three columns correctly.

What css changes do I need to make in order to display the third column correctly?

Check If you can do the following changes. I just added class

  .wizard-parentcontrol div
  {
     float:left;
  }

and removed the hardcoded width's of 33% and 30% from your code.
