Statically, it’s like style =  
“background-image:url(/images/wiki/skyRamp.png)”

Dynamically, it might be page[‘td\_id’][‘style’].backgroundImage =  
“url(…)”

Someone should check my JavaScriptGenerator syntax, but that’s where I  
would start…

Oh, that kind of “dynamic”!

Here’s my output:

(I built that with Builder::XmlMarkup, not ERb. Don’t try that until  
you learn more programming!)

Now you can put the \<%= %\> anywhere in there that you like, replacing  
as much or as little of the source as you need, so long as ERb can
