How to find DOM elements that cause body overflow

Sometimes you may notice that your website displays an unintended horizontal scrollbar. You may be wondering what is the cause.
Most often this issue is caused by the DOM element being wider than a document.
You can try to find this element in the web inspector, but there is a great and easy JS solution that will console log all elements that go beyond the screen:
var docWidth = document.documentElement.offsetWidth;
[].forEach.call(
document.querySelectorAll('*'),
function(el) {
if (el.offsetWidth > docWidth) {
console.log(el);
}
}
);
That's it, no need to waste your time searching for overflowed elements anymore!
