* SUMMARY CSS: Report missing vendor prefixed properties. When we do Reports, a useful CSS report feature to have would be warning about missing vendor prefixes on properties/rules. Examples: - warn if something is vendor prefixed without an un-prefixed equivalent - warn if someone has one prefix but not other prefixes - not just properties, also keyframes: @-webkit-keyframes, @-moz-keyframes, ... The amount of warning could be customizable within a report.
