Spacing on pages.

Hi I have spent a lot of time trying to lay our my pages on the website nicely.  I have yet to complete a single page as I keep getting lots of space in between text and pictures (see the page aimed at colleges).  This space does not appear when I am in the edit mode which begs the question, what is the point of providing an edit function if the view does not resemble the published article.  Your help would be greatly appreciated. http://www.theadventureventure.com
