Hi, We discussed and decided in the past that the "computed style” of the ‘transform’ property must return the specified value [1]. This has been in the spec since the first WD. Yet, no browser ever implemented this part of the spec. For what it’s worth, all browsers seems to return a matrix()/matrix3d() string. Even if we had the agreement from browser implementers in the past to change the behavior, no browser ever did and users are starting to rely on a matrix as returned value. I suggest we specify the behavior of browsers and do not return the specified value. Implementations must return a string “matrix()” with 6 numerical values on a pure 2D matrix[2] (all transform functions multiplied as in [3]) and a string "matrix3d()” with 16 numerical values otherwise.
