What are you trying to accomplish?

Pseudo-elements are not actually part of the DOM, so you can't target a node with JavaScript. However, you are able to return any styles associated with it. Refer to this article.

const content = window.getComputedStyle(
  document.querySelector('div'), ':before'
).getPropertyValue('content');
