I prefer to offer minimal styling hooks — - enough to be able to target pretty much any element, but I don’t like to clutter the code with a lot of them. In this case, the HTML produced is so simple that it was hardly relevant!

I’ve gone both ways with the initial styling. I’ve provided it in some cases, but usually not. Still, it certainly can be valuable to provide guidance at least in respect to what hooks are available.

What I do do, and not sure if you do, is I also include plenty of styling hooks and I offer a stylesheet showing all the elements, classes, and IDs used as well as some basic styling so it’ll look decent on most sites right out of the box. I figure that will be really helpful to the end-user, even if my choice of colors doesn’t match, because the file exists, it (and mentioned in a readme) indicates to the user that they may have to tweak the styles. It keeps them from belly-aching.

Too bad the guy didn’t offer a reply email, you could have pointed out the need to style to him.

In regards to your question I think some basic help is a good idea. I would rather use script from someone who I know who will give me solid help than someone who does not.
