When using images with no size set, it should use the calculated available space set bij css attributes. parent width is 60px. child has with position:absolute set and values set for top, left , right and bottom the width and height is not used for rezising the image. The image use his own or even a different value. Ai not good. See code and images supplied.

This is a bug in Firefox. Note that I don't really like what is specified in CSS2.1 at the moment, but nevertheless Firefox is incorrect. If left/right are non-auto and width is auto, the intrinsic size of the image is used. It does not stretch (as say a block flow would) to fill the space. This is outlined very clearly in CSS2.1. I think the spec needs to be changed, since we've gotten this report both internally in Radar and externally in Bugzilla, so I will keep this bug open for now.

My mistake, you are right about that. But if I understands it (
http://www.w3.org/TR/CSS21/cascade.html#inheritance
) well then when I ( using the code above ) have a container arround the img ( between navElement and NavImg ) with something like .navElmCont { margin: 0px 5px 20px 5px; width:auto; height:auto; } then safari doesn't honor the calculated parental width values even when I cahnge the width and height values to inherit into the image. Like .navImg { ... width: inherit; height:inherit; } 6.2 Inheritance reads ( When inheritance occurs, elements inherit computed values. The computed value from the parent element becomes both the specified value and the computed value on the child. )

In this case what is inherited is the value "auto", so Safari's rendering remains correct in terms of the spec.

We believe this is correct behavior.
