title: Getting Border Width in jQuery
body: <p>I have to position a popup element dynamically inside a container.  I'm trying to get the border width of the container.  I've found several questions like this one:</p>
  
  <p><a href="https://stackoverflow.com/questions/3787502/how-to-get-border-width-in-jquery-javascript">How to get border width in jQuery/javascript</a></p>
  
  <p>My problem has been discussed but I haven't found any answers.  How do you get the border width when the property is thick, thin, or medium?</p>
  
  <p>There's word on the street that you can usually expect thin, medium, and thick to be 2px, 4px, and 6px respectively, but the CSS spec doesn't require that.</p>
  
  <p>Has anyone run across an easy (or if not easy at least consistent) way to get the width of the border on one edge of a DOM element?</p>
