This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Examples of browser specific properties: /* Mozilla, since 1999 */ Value Error : white-space -moz-pre-wrap is not a white-space value : -moz-pre-wrap /* Opera 4-6 */ Value Error : white-space -pre-wrap is not a white-space value : -pre-wrap /* Opera 7 */ Value Error : white-space -o-pre-wrap is not a white-space value : -o-pre-wrap /* Internet Explorer 5.5+ */ Property word-wrap doesn't exist : break-word also internet explorers "zoom: 1" is not recognized as browser specific.
Fixed, the vendor specific values can now generate warnings instead of errors (as they can't be validated by definition)
