Looking much better.  See  
http://beallsprings.org/sandbox/Mod%20DOM%20test3.html (version 2 blew up  
on the launch pad...)
Leaving my modification code in a function, I used:

<body style="display:none;"
   onload='animInit();document.body.style.display="block"'>

combining Dr. S's suggestion and Evertjan.'s correct syntax with an  
invocation of the function

Which works on Firefox (15 seconds), Safari (12 seconds), Chrome (12  
seconds), and IE (15 seconds).  Opera duration stays at 1 second, but  
inspection with Dragonfly shows that both the Style and Computed style  
reflect a change to animation-duration (no prefix) to 15 seconds.  So the  
change takes place, but the rendering engine uses only the unmodified  
value.

Incidentally, Safari and Chrome both ignored animation-timing-function,  
instead using the default 'ease'.  Adding  
-webkit-animation-timing-function: linear; brought them to heel.

As it turns out, the particular target audience for my original effect  
does not use Opera, so for me this issue is resolved, although the  
solution is clearly not yet a completely generic fix.

Now to integrate what I've learned into the actual web page.

Thanks to all,
