Detecting HTML Text Overflow with Ellipsis

In scenarios where overflowing text is trimmed and an ellipsis is displayed using CSS, it can be useful to detect which elements' contents are overflowing via JavaScript. Here's how to achieve this:

This function evaluates whether the element's visible width (offsetWidth) is smaller than its actual content width (scrollWidth), indicating content overflow. By invoking this function with the desired element, you can determine whether ellipsis activation is applied due to overflow.
