                       If using 'side' menu, must be tall enough to hold all tab names!
| --- Content ---
| tab_1              = name of tab (i.e., Something)
| content_1          = contents of panel (i.e., Here's some content about something.)
| tab_2              = name of tab (i.e., Another Thing)
| content_2          = contents of panel (i.e., Content about this other thing.)
[...]
| tab_N              = name of tab (i.e., Something Else)
| content_N          = contents of panel (i.e., Some information for this last thing too.)

You can have as many tabs/panels as you like, tab_1 through tab_N, but you don't need more than two (well, technically you only need one, but then why bother?). It may also get cluttered if you have too many tabs, but that's a matter of taste. contents_# can be as complicated as you like, as long as nothing is left open.

The appearance can be adjusted more by writing custom css.
