Cool background! For the CSS stuff you need to put this:
[*css-div=" color: white;cursor: crosshair; background-image:url("{image url}"); width: {image width}px; height: {image height}px; font-size: 10px; text-align: right;"]
{Text & stuff goes here}
[/css-div]
And to make the rollover text:
[*title={rollover text}]{Text}[/title]
Replace the stuff in {these} brackets with what you want, get rid of the brackets aswell.
