This feature is pretty good but you should add some documentation in the README.md.

This does not cover the base container class, which is hardcoded to be highlight in Hexo, but hljs in current stylesheets. It seems Hexo's structure is overall not quite true to hljs, but changing line 47 to use the selected prefix instead of 'highlight' as class works with the original stylesheets provided by hljs nevertheless.

The one pitfall here is that the class applied to the container would become hljs- and not hljs, or the other way around it'd be hljsnumber instead of hljs-number so I guess the simplest solution would be to automatically append a - to the option passed to hljs while internally using the provided class.

Edit: tried implementing in #29
