License clarification

The license file mentions that all .html files and .css files are CC licensed. Was the intent here to license just the documentation under a CC license? I notice there are several demo.css files that have Apache license headers which seem at odds to the statement in LICENSE. Can you confirm that these files and the scss files are Apache licensed.

Background for asking is that CC is not entirely compatible with the Apache License [2] and can only be included in a binary form by Apache policy. [1] This makes css files licensed under CC a little difficult to deal with.
