css - Nesting pseudo-elements inside pseudo-elements

Question

I have a :before for an opening 'quote' and an :after for a closing quote.

Now what I want is an :after:after for the 'cite' reference but I cant get it to work.

Does anyone know if this is possible?

My code so far:-

blockquote:before { content: '201C'; }
blockquote:after { content: '201D'; }

blockquote {
  font-size: 22px;
  line-height: 24px;
  text-indent:60px;
}
blockquote:before {
  font-size: 170px;
  margin-left: -136px;
  margin-top: 50px;
  opacity: 0.2;
  position: absolute;
  overflow:visible;
  float:left;
  width:135px;
}
blockquote:after {
  float: right;
  font-size: 170px;
  margin-right: 35px;
  margin-top: 33px;
  opacity: 0.2;
  overflow:visible;
  width:135px;
}
blockquote[cite]:after:after {
    display: block;
    text-align: right;
    content: "2014 " attr(cite);
    font-style: normal;
    font-size: 0.8em;
    }

Answer 1

The idea of nesting ::before and ::after pseudo-elements has been proposed; see this section of the Generated and Replaced Content module. However, that module has been abandoned pending a complete rewrite, so I wouldn't hold my breath on this document ever receiving implementation until it's republished. And even then, whether nesting content pseudo-elements will still be a thing is as yet unknown.
