When I use the Thottbot code the tooltip stretches right across the screen. On other websites the tooltip looks correct so I am assuming its not my browser. However I also use the wowhead code and that works fine.
For example this item Lightbringer Faceguard
the following text is on one line:
"Equip: Increases damage and healing done by magical spells and effects by up to 43."
the same item on the using the wowhead code comes out on 2 lines making the formating look correct. Any one got any ideas?

On further investigation it looks like the tooltip is being alligned with the right hand side of the screen so if I resize my window making it narrower I can get the tooltip to appear normal. On other websites this doesnt happen.

If i take the following out of my css file it works but leaves the rest of the site messed up
table {
width: 100%;
padding: 0}
