Hello,
On the MDN transform-box reference page the initial value is specified as ‘border-box’ whereas the specification defines the initial value to be view-box.
I am assuming that this is an issue, rather than being intentional. Please correct me if I am wrong. I am unsure how to fix it so I’m pointing it out here if anyone has the time to do it.
Also, if you happen to figure out what view-box means don’t hesitate to explain it to me… I will buy you coffee if we meet.
