<!-- 
   Notes on CSS media types used:
 
   1) projection -> slideshow mode (display one slide at-a-time; hide all others)
   2) screen     -> outline mode (display all slides-at-once on screen) 
   3) print      -> print (and print preview)
  
   Note: toggle between projection/screen (that is, slideshow/outline) mode using t-key
