The inline HTML is quite strictly filtered. I remember some months ago trying to get some Javascript to load and being unable to do so. Just now I checked that you cannot define styles as well. You can assign class attribute, but not id. I think it's more trouble than it's worth trying to render a nice line-numbered source code using that mechanism.
