Create a div named news.  
Text scrolls from bottom to top.
Adjust vars to position as required.
var theTop = 360;  The position where the scrolling text will disappear.
var theHeight = 190;(This is now calculated automatically from the scrollHeight property.
var theWidth = 190; Adjust as required.
var theLeft = 0; (optionally use padding)
var toClip = 160; (the number of pixels which will be cut from the bottom of the div)

Adjust padding (theDiv.padding = "160px 0px 160px 15px";) [top right bottom left]

Style as required.
