           Summary: Matched declaration cache
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: koivisto at iki.fi


Sets of style declarations are applied repeatedly for different elements when calculating the document style. The same set off applied declarations result in the same non-inherited style, independent of the element and its context. We can use this to build a cache to speed up style applying and to share more style data for reduced memory usage.
