http://dev.w3.org/csswg/cssom/#the-cssstyledeclaration-interface [[ For each CSS property property that is a supported CSS property, the following partial interface applies ]] But it should not apply for float, right?
Alternatively, why not just make float part of CSS property to IDL attribute? Also, providing a reference from CSSStyleDeclaration to this partial interface stuff would be useful.
