| 8 | * |
| 9 | * This Plug-In will create a custom tooltip to replace the default |
| 10 | * browser tooltip. It is extremely lightweight and very smart in |
| 11 | * that it detects the edges of the browser window and will make sure |
| 12 | * the tooltip stays within the current window size. As a result the |
| 13 | * tooltip will adjust itself to be displayed above, below, to the left |
| 14 | * or to the right depending on what is necessary to stay within the |
| 15 | * browser window. It is completely customizable as well via CSS. |
