A function that returns the size of an element.
With a reference to an element, you can use the ElementRect utility to get the bounding rectangle of the element.

<script lang="ts"> import { ElementRect } from "runed"; let el = $state<HTMLElement>(); const rect = new ElementRect(() => el); </script> <textarea bind:this={el}></textarea> <p>Width: {rect.width} Height: {rect.height}</p> <!-- alternatively --> <pre>{JSON.stringify(rect.current, null, 2)}</pre>
