title: How to add border in OpenLayers map popup in drupal
body: <p>Hi I have to add a border in an OpenLayers popup. I have searched for this but didn't find any article about it. However I did find a function to add a border but I didn't know how to use the function (like <code>setBorder:function()</code>) in the drupal module file openlayer.js.
  I think it would be easy if I was using OpenLayers API but here I am using a drupal module for OpenLayers.</p>
