- The menu's fontsize and button dimensions are specified in 'em'
units. The menu's width is 7.5em (same as the left
column width). Change the default
fontsize in your browser to see how the menu can
be scaled up or down...
...and note how the width of the left column (but not the right column) also changes. - The menu is relatively positioned at (0, 0) within a <div> named 'leftnav' that is part of the flowed content in the sidebar on the left.
