The goal of a pure CSS hamburger is a noble one that I applaud and share.
However, it's actually okay to introduce JS for the progressive enhancement to accessibility because ARIA is by definition dependent on RIAs.
In regards to the overall construction of these I also rather like the form:valid hack, rather than the checkbox hack depicted, since the former is more general (in particular, the selectors can be ancestors instead of siblings).
