/**
|
|
* The bgiframe is chainable and applies the iframe hack to get
|
|
* around zIndex issues in IE6. It will only apply itself in IE
|
|
* and adds a class to the iframe called 'bgiframe'.
|
|
*
|
|
* It does take borders into consideration but all values
|
|
* need to be in pixels and the element needs to have
|
|
* position relative or absolute.
|
|
*
|
|
* NOTICE: This plugin uses CSS expersions in order to work
|
|
* with an element's borders, height and with and can result in poor
|
|
* performance when used on an element that changes properties
|
|
* like size and position a lot. Two of these expressions can be
|
|
* removed if border doesn't matter and performance does.
|
|
* See lines 39 and 40 below and set top: 0 and left: 0
|
|
* instead of their current values.
|
|
*
|
|
* @example $('div').bgiframe();
|
|
* @before <div><p>Paragraph</p></div>
|
|
* @result <div><iframe class="bgiframe".../><p>Paragraph</p></div>
