Example
The following example shows four ways to use the allowTransparency attribute, with and without the background-color attribute. Because the allowTransparency attribute of Frame1 is set to true
, Frame1 renders red, the background color of the parent document. The allowTransparency attribute of Frame2 is also set to true
, however the background-color attribute of Frame2 is set to green
, so Frame2 renders green. Because the allowTransparency attribute of Frame3 is set to false
(the default value), Frame3 renders white, the color of the t:SRC document. The allowTransparency attribute of Frame4 is also set to false
, so Frame4 renders white even though the background-color attribute of Frame4 is set to green
.
