Q:

You want only a vertical scrollbar and no horizontal scrollbar on your page. How would you do it?

Answer

- This can be done by defining the frame with SCROLLING = auto and having content to just fit into this frame. 


- SCROLLING="yes" gets the scroll bar on both the sides, even when not needed. 


- SCROLLING="no" doesn’t get the scrollbars at all, even when they are needed.
