Get elements bigger than viewport	snippet	javascript	browser	case-study	2020-10-22T20:23:47+03:00

Returns an array of HTML elements whose width is larger than that of the viewport's.

• Use HTMLElement.offsetWidth to get the width of the Document.
• Use Array.prototype.filter() on the result of Document.querySelectorAll() to check the width of all elements in the document.

const getElementsBiggerThanViewport = () => {
  const docWidth = document.documentElement.offsetWidth;
  return [...document.querySelectorAll('*')].filter(
    el => el.offsetWidth > docWidth
  );
};

getElementsBiggerThanViewport(); // <div id="ultra-wide-item" />
