 `sanitize_html_class` excludes some increasingly common valid html
 characters.
 In particular the `@` character.
 The use of `@` may not be extremely common for class names but it is being
 encouraged by some pretty renowned folks in the area of class naming
 conventions. http://csswizardry.com/2015/08/bemit-taking-the-bem-naming-
 convention-a-step-further/#responsive-suffixes

 Actually pretty much anything is now valid for html classes except for
 spaces or tabs. I also use the `/` quite a bit in my classes but I thought
 I'd start with the `@` .
