How to display language-specific quotes in CSS

Stefan Judis:

Quotation characters are language-specific. French, for example, uses « and ». Going all in with double quotes isn’t correct and will anger quite some typography nerds (and French people).

I love this attention to detail and totally didn’t know you could do the following and browsers will pick the right kind of quote depending on the user’s language:

blockquote::before {
  content: open-quote;
}

blockquote::after {
  content: close-quote;
}
