I have a way that I want to be able to show users help. I have a nice ? icon for this purpose and I have
added a title to the image itself which will display as a hover. I have added the image to a Panel Page via a Panel Pane by the Node ID assigned by Drupal, in this case 960. But I want it to overlay a different pane. So, I place the Pane with the image at the bottom and then I use a CSS rule that affects only the node 960. See the screen shots. I simply add the position of absolute and the proper margin spacing to get the image where I want it to be.
Since the CSS is based on a specific node, which is presented by Drupal as an ID, the CSS rule is formatted like this. Done and done.
margin:-69em 0 0 47em;
