File tools/dom/templates/html/impl/impl_CSSStyleDeclaration.darttemplate
(right):

https://codereview.chromium.org/21182002/diff/11001/tools/dom/templates/html/...
tools/dom/templates/html/impl/impl_CSSStyleDeclaration.darttemplate:28: class
$(CLASSNAME)Set $EXTENDS with $(CLASSNAME)Mixin {
I don't think that this one should extend Interceptor, just Object.

Also probably just use the class name rather than $CLASSNAME macro, it's more
readable here and stuff cannot be renamed without code changes anyways.

https://codereview.chromium.org/21182002/diff/11001/tools/dom/templates/html/...
tools/dom/templates/html/impl/impl_CSSStyleDeclaration.darttemplate:54: String
getPropertyValue(String propertyName) {
This should probably be on the single element one, no?

https://codereview.chromium.org/21182002/diff/11001/tools/dom/templates/html/...
tools/dom/templates/html/impl/impl_CSSStyleDeclaration.darttemplate:78: static
bool get supportsTransitions {
Since its a static, should be on the CssStyleDeclaration rather than mixin.
