Basic example using Element.pseudo
Using pseudo-elements, most modern browsers will automatically add quotation marks around text inside a <q> element. (A style rule may be needed to add quotation marks in older browsers.) The example below demonstrates the basic properties of the CSSPseudoElement object representing the opening quotation mark.
const element = document.querySelector("q");
const cssPseudoElement = element.pseudo("::before");
console.log(cssPseudoElement.element); // Outputs [object HTMLQuoteElement]
console.log(cssPseudoElement.type); // Outputs '::before'
