prefixes

When declaring say box-shadow or text-shadow or gradients for that matter, do you still need all the prefixes? -webkit-box-shadow: inset 0 0 1px 1px #e3e3e3; -moz-box-shadow: inset 0 0 1px 1px #e3e3e3; -ms-box-shadow: inset 0 0 1px 1px #e3e3e3; -o-box-shadow: inset 0 0 1px 1px #e3e3e3; box-shadow: inset 0 0 1px 1px #e3e3e3; I understand the main ones: -webkit- -moz- box-shadow But with the growth of browsers, I wanted to try to get an updated view on whether it is necessary to use 5 prefixes at this moment?

Does anybody have a

I digitally sign XML files, but need the signature tags contain the namespace prefix "ds". I researched quite the google and found many of the same questions, but no satisfactory answer. I tried to put the "ds" manually in the file, but the signature becomes invalid. The tag "SignatureValue" signs the tag "SignedInfo" so the signature becomes invalid. Could somebody show me how I generate the value of the tag "SignatureValue" so I can replace the signature after adding the prefix "ds"? Apparently a lot of people ran into the same problem. After investigating source code of the class Signature
