The goal is to 'soften' hyperlinks off to external content slightly by displaying an external link bar at the top of the window, that displays above the content on the external website - containing a line of text that reads something along the lines of "The content you are viewing is not owned by this site, close this browser window to return to site name".
I know there's a way to achieve this using frames, but as far as I understand it frames are bad news for accessibility. Furthermore, if the user then accesses a site which itself has a frame set, there can be all sorts of fun and games!
Would welcome any feedback. Could something like this be achievable with jQuery perhaps?
