How to find DOM elements that cause body overflow

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!
