Yes, you are right. I removed that widget and the black area at the bottom disappeared.
It was the animation that floated up from the bottom that was causing the problem. I changed it to a different animation and it is all better now! While I was doing this I also figured out how to make the font size of the words larger. I must say that I am impressed with your themes and support Andre. Now I have attained a lot of knowledge about HTML and CSS than I ever thought was possible before.
