White Space in between post title and post

I am very new to WordPress and still learning. I had a blogger account and recently moved everything over to WordPress. There is white space in between the title and the actual contents of my post. I would like to eliminate this. I also noticed the same issue when I copy and paste into a new post. The only time there isn’t white space is if I type in the blog. Could someone please help? I have spent a few hours going through the forums and trying different things in Simple Custom CSS You can see an example at http://www.sailinghound.com/the-crew where there is a large gap in between the title "The Crew" and the picture. Thanks, Nathan
