Sorry, but I don't know what you mean by "they are for the scrollers", or "how to make an htm page stand alone".
I'm not even sure why you are saying "htm page". Are you asking about the difference between .html and .htm???
Instead of asking a question in a reply, as you have done just now, if would be better (you will be more likely to get good answers) if you select a forum and begin a new thread to ask your question. I'm not sure if your question concerns Web Design or HTML Coding, because I'm not sure what you want to do.
