How to debug overlapping div elements?

Question

I am looking for a guideline to check when div( using bootstrap grid or not ) elements are overlapping. So far, I have checked the position and mismatched tags using chrome developer tool.

You are looking for collision detection. The following Javascript code shows how to detect overlapping HTML div tags. Please find more here: How to detect overlapping elements

function collision($div1, $div2) {
  var x1 = $div1.offset().left;
  var y1 = $div1.offset().top;
  var h1 = $div1.outerHeight(true);
  var w1 = $div1.outerWidth(true);
  var b1 = y1 + h1;
  var r1 = x1 + w1;
  var x2 = $div2.offset().left;
  var y2 = $div2.offset().top;
  var h2 = $div2.outerHeight(true);
  var w2 = $div2.outerWidth(true);
  var b2 = y2 + h2;
  var r2 = x2 + w2;

  if (b1 < y2 || y1 > b2 || r1 < x2 || x1 > r2) return false;
  return true;
}
