Noob here. I need vertical autoscrolling text inside a box that will stop scrolling after the user clicks on the scroll bar inside the box.

The box will contain a list of domain names that my client is selling that will scroll down to up. When the end-user wants to scroll themselves they can take control of the scroll bar. I want the text to be white and everything else transparent except the scroll bar.

Thank-you for any assistance you may be able to offer!
