Currently experimenting with adjusting the height of a pseudo element using Typescript.
An error is popping up in my IDE (vscode) as I go along.
This is the code snippet I am working with.
// choose element
let el: HTMLElement = document.getElementById('filter-container');
// adjust the height of the pseudo element
el.pseudoStyle("before", "height", newHeight);

To customize a pseudo-class for a specific element, you must modify the CSS stylesheet itself:
document.styleSheets[0].insertRule('#element:hover { color: red; }', 0);
document.styleSheets[0].cssRules[0].style.color = 'red';
give it a shot:
element.prototype.pseudoStyle("before", "height", newHeight);I believe that in JavaScript, it's not possible to modify pseudo elements, and I suspect the same limitation applies in TypeScript since it is based on JavaScript. Warm regards.
