Detecting element causing CSS overflow

CSS overflows are an annoyance that keep showing up once in a while and are really hard to debug. Unwanted and unexpected scrollbars can lead to hours of inspecting the DOM to figure out what element is causing the issue and clicking random elements in the Chrome dev tools until you find the culprit.

A simple programmatic way of figuring out what is causing the issue can be:

- Advertisement -
document.querySelectorAll('*').forEach(elem => {
  if (elem.offsetWidth > document.documentElement.offsetWidth) {
      console.log('Problem child: ', el);

This will log all the elements that have an offset width greater than the document’s width and then conveniently decide what to do with it!
