How do i create blank rows/lines between my header and the controls under the header?

I am working with a Details View which has a header and is then followed by fields and edit controls.
How do I place one or more blank lines between the header and the controls which are underneath the header?
Currently the controls are up to close the the header with no spacing after the header. How can I fix this?

You can drop my code into a web form to see how it looks if you wish.
