I used jQuery to create a copy of a div and positioned it on the page, but for some reason, it's not displaying. When I checked using F12 tools, all the properties such as top, left, height, and width seemed to be set correctly.
<div id="divLine" style="width: 12px;height:16px;background-color: #000"></div>
var clone = $("#divLine").clone().prop('id', 1)[0];
$(clone).css({
position: 'absolute',
left: 20,
top:20
})
