Basic example using Element.pseudo

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'
