/*
Three different behaviors desired:

1. all content on one page
-all content is initially visible for no-js. js hides all except "default"

2. content is on subpages, transcluded
-"no-js" content is initially visible, the rest hidden. js hides "no-js" and shows "default"

3. ajax
-"no-js" content is initially visible. js removes "no-js" and calls for "default"
