You would need to adjust the script to solve that problem which is a question for the JS forum.
As an example use css terminal and add the following code to your live site so you can see how it would look with a css version.
margin: 34px auto 0;
margin:0 auto 0 !important;
position: relative !important;
Of course that assumes a fixed height for the layout but it looks like that's what you have anyway.
