Certain properties just aren't implemented, and box-type properties like margins, borders and padding aren't properly implemented for inline elements like SPAN or CODE . However, there are also problems that aren't mentioned in the release notes, and I'm concerned that these problems suggest deeper issues with iCab's CSS rendering engine. For a start, there are problems with its support for the box model . Worse, they are added onto margins and padding that you specify, instead of being replaced by them. While backgrounds and margins on inline elements aren't really supported, they fail in different ways depending on whether the element is inside a table or not .
List items seem to be treated as inline elements rather than block elements .
Bold and italic styles don't always inherit properly either, at least if the sidebar on MacEdition pages is any guide. Thanks for your feedback. We know about most problems, and they will be addressed in the next versions of iCab. This is sometimes very difficult or even impossible so it will need some time to find a good solution. This is the cost of the bad markup out there .
