MediaLinks Style SheetDeveloped by John Foliot / Stanford Online Accessibility Program (http://soap.stanford.edu)

This is an additional stylesheet (medialinks.css) which can be incorporated into Drupal (or used stand alone) that does some checking of links based on file extension type, and add an appropriate icon after the link showing the file format. For example, a link to a PDF file will auto-magically also show a Acrobat icon directly after the link, as part of the link; current formats supported include PDF, DOC, DOCX, XLS, and PPT. It also has a new CSS authoring class called “external” which also provides an icon after a link, indicating that it is a link off of the current site.
