[Div + CSS] IFRAME highly adaptive in IE6 surfaced penetration Solution

In IE6, an IFRAME is usually needed for the surfaced layer to be penetrated by obj. This is the most effective solution currently, but this solution has its own shortcomings, that is, the height of IFRAME cannot be adaptive. Maybe you will think that setting a height of 100% for IFRAME is not enough? Unfortunately, this problem cannot be solved. One solution is to use the script to obtain the height of the surfaced layer and then assign it to IFRAME. The disadvantage is that the script is required to support and consume more system resources. Another solution is provided: <! -[If IE 6]> <IFRAME frameborder = "0" style = "position: absolute; left: 0; top: 0; width: 100%; Z-index:-1; filter: alpha (opacity = 0); Border: solid; "> </iframe> <! [Endif]-> CopyCodeNote: The percentage height cannot be defined for IFRAME.
