Document: elementsFromPoint() method

elementsFromPoint() method
of the {{domxref("Document")}} interface returns an array of all elements
at the specified coordinates (relative to the viewport).
The elements are ordered from the topmost to the bottommost box of the viewport.
It operates in a similar way to the {{domxref("Document.elementFromPoint", "elementFromPoint()")}} method.

Parameters
x
: The horizontal coordinate of a point.
y
: The vertical coordinate of a point.

HTML
<div>
  <p>Some text</p>
</div>
<p>Elements at point 30, 20:</p>
<div id="output"></div>
JavaScript
let output = document.getElementById("output");
if (document.elementsFromPoint) {
  let elements = document.elementsFromPoint(30, 20);
  elements.forEach((elt, i) => {
    output.textContent += elt.localName;
    if (i < elements.length - 1) {
      output.textContent += " < ";
    }
  });
} else {
  output.innerHTML = `<span style="color: red">
