{{APIRef}}{{SeeCompatTable}}
The CSSPseudoElement interface represents a pseudo-element that may be the target of an event or animated using the {{DOMxRef('Web Animations API', '', '', 'true')}}. Instances of this interface may be obtained by calling {{DOMxRef('Element.pseudo()')}}.
{{InheritanceDiagram}}
CSSPseudoElement extends {{DOMxRef('EventTarget')}}, so it inherits the following methods:
Using pseudo-elements, most modern browsers will automatically add quotation marks around text inside a {{HTMLElement('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'
