While they understand the complaints, their primary goal is to create a browser which works well for users - who outnumber developers by many thousands to one. Opera make a reasonable case to justify their decision. If it turns out that there are differences big enough to cause breakage, we will consider our options, one of which is to align the behavior of our -webkit- prefixed variant to what WebKit actually does. ![]() With regard to differences in behavior, Opera state:Īs far as we can tell, the behavior the properties that we have aliased is identical in WebKit and Opera, or at least close enough that the differences will not matter in practice. If you’ve defined -webkit-border-radius, -o-border-radius and border-radius, normal CSS cascading rules apply and the last defined rule or most appropriate selector will be applied, e.g.Īll properties are considered to have equal priority so Opera applies a border radius of 9px.
