Brian,
I downloaded the source code and the ch02/index.html ran fine on
Chrome. WebGL does not work for my display driver but that is
another issue. I guess the problem is not in DOM but that
scripts not executed because both JHS and that webpage want to
set the handler for onload event.
Note that if I comment out the scripts by changing "script" to
"noscript" in line 9 and 10, then the index.html will not display
text. The reason may be that in line 20 of main.css it set
display to none. If you change that "none" to "block", then text
will re-appear.
Alternatively, if you also comment out line 7 and 8, change
stylesheet to nostylesheet, text will also appear but without
those fancy fnot.
IMO, given that JHS is a framework for generating dynamic
webpage, it can have problem with some javascript library out
there. If you want to learn from that book, then you need to
put JHS aside. When you have learnt enough HTML5 and javascript,
you can write webpage using HTML5/javascript that communicate
with a J server for computation.
index.html
