* Version 1.3 - Updated: Mar. 23, 2010
|
||
|
|
*
|
||
|
|
* This Plug-In will create a custom tooltip to replace the default
|
||
|
|
* browser tooltip. It is extremely lightweight and very smart in
|
||
|
|
* that it detects the edges of the browser window and will make sure
|
||
|
|
* the tooltip stays within the current window size. As a result the
|
||
|
|
* tooltip will adjust itself to be displayed above, below, to the left
|
||
|
|
* or to the right depending on what is necessary to stay within the
|
||
|
|
* browser window. It is completely customizable as well via CSS.
