This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The CSSPseudoElement
interface represents a pseudo-element that may be the target of an event or animated using the Web Animations API. Instances of this interface may be obtained by calling Element.pseudo()
.
Properties
CSSPseudoElement.element
Read only- Returns the originating/parent
Element
of the pseudo-element. CSSPseudoElement.type
Read only- Returns the pseudo-element selector as a
CSSOMString
.
Methods
CSSPseudoElement
extends EventTarget
, so it inherits the following methods:
EventTarget.addEventListener()
- Registers an event handler of a specific event type on the pseudo-element.
EventTarget.dispatchEvent()
- Dispatches an event to this pseudo-element.
EventTarget.removeEventListener()
- Removes an event listener from the pseudo-element.
Examples
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'
