The examples below show the variety of tooltip "Positioning" options:

Mouse over this link to see a tooltip with default positioning.

See a tooltip positioned in a different corner if you mouse over this link.

Mouse over this link to see a tooltip positioned in a different way.

Mouse over this link to see a tooltip with adjusted positioning.

Mouse over this link to see a tooltip that follows the mouse movement while it remains over the link.

Mouse over this link to see a tooltip that appears under a different target (1st link under this section).

Mouse over this link to see a tooltip used in a different way: it appears next to the image below as an explanation.

The direction of the tooltip can shift if the Tooltip that opens is about to cross the window's boundaries (the window in this case is this iframe). Place the mouse on words 'Tooltip' and then 'opens' to see this.

Mouse over the image below to see a different tooltip for each logo. This is a single image that uses mapping to split it into areas. Each tooltip appears on a different area on this single image.
