For tiny monitors, I wanted to allow the user to slide the menu/TOC off
to the left so that the whole screen could be used for viewing the right panel
content. This is implemented by calling a java script function using an anchor tag,
see yellow highlight. The java script: (1) sets an object reference for each
element that needs to move left/right on a toggle, (2) determines the open/close
status of the menu, then (3) moves the elements. This java script is adapted from
Visual Quickstart Guide CSS, DHTML, and Ajax, Fourth Edition
by Jason Cranford Teague.
