``The contents of an \verb=\hbox{}= are not rendered by jsMath, but
instead are used as plain text in the browser.  JsMath allows you to
include HTML commands through the (rather awkward) means of using
@(...) in place of \verb=<...>=.  For example, \verb=\hbox{@(tt)=
  monospaced \verb=text@(/tt)= would get the enclosed text in the TT font.''
The above also holds for \verb=\text= instead of \verb=\hbox=.
