It's wouldn't be possible if you're only using CSS. See this stackoverflow post [1], or more specifically the spec it references [2] on the CSS content property (used by this library). The acceptable values are: normal | none | [ string | uri | counter | attr(identifier) | open-quote | close-quote | no-open-quote | no-close-quote ]+ | inherit You might think, maybe you could insert html by putting the html on an attribute and using the attr() value, but reading further: This function returns as a string the value of attribute X for the subject of the selector. The string is not parsed by the CSS processor.
