title: Using jQuery to find an element at a particular position?
body: <p>Is there a method in jQuery to select an element located at a particular position?</p>
  
  <p>For example, can I select the element that is located at left:100 and top:300 in absolute position?</p>
  
  <p>It would be nice if I could select an element located in a range of positions, for example, select the element that is located left: 100 - 150 px top 200 - 280px.</p>
