I understand (because the specification explains it very clearly) why it is necessary to have the special syntax of ::before(n); because ::before::before and ::before(2) are different. However, I am not clear why special syntax of ::outside(n) is needed because I can't see any difference between ::outside::outside and ::outsize(2). The specification does not explicitly prohibit ::outside::outside (so I presume that it is valid) but also does not mention it either. Is ::outside::outside allowed? How does it differ from ::outside(2)?Received on Tuesday, 8 June 2010 13:49:13 UTC
