quotes

The quotes CSS property sets how the browser should render quotation marks that are added using the open-quotes or close-quotes values of the CSS content property.

none

The open-quote and close-quote values of the content property produce no quotation marks.

auto

Appropriate quote marks will be used for whatever language value is set on the selected elements (i.e. via the lang attribute).

[<string> <string>]+

One or more pairs of <string> values for open-quote and close-quote. The first pair represents the outer level of quotation, the second pair is for the first nested level, next pair for third level and so on.

none | auto | [ <string> <string> ]+

HTML

<q>To be or not to be. That's the question!</q>

CSS

q {
  quotes: '"' '"' "'" "'";
}
q::before {
  content: open-quote;
}
q::after {
  content: close-quote;
}

Result

For most browsers, the default value of quotes is auto (Firefox 70+), or the browser otherwise had this default behavior (Chromiums, Safari, Edge), so this example works without it being explicitly being set.

HTML
