screenposition is useful for websites that are centered in orientation. By declaring "center" for screenposition, this will ensure that the menu will remain centered at all times. Other options for screen position are top, left, right, middle or bottom, plus a combination of 2 valid properties separated by a semi colon. Offsets can be declared for both top and left. The syntax for offsets is "offset=-100"; this will move the menu 100 pixels back from either top or left depending on the screenposition you have used.
