Burning web pages into CD

I don't have any idea how a web pages work when you copy into a CD. But I guess it will work normally when you're online. I'm not sure about this.

This was the question that bothers me now since a young girl came to me asking to burn her HTML projects onto a CD. And this is my first time to burn something like this, of which is the most common way I know is to burn it as data only. I've already gone into burning CD but not too familiar on burning web pages. She never told me beforehand that those files were to be submitted to her teacher and just burn it from a USB.

After burning, she's expecting that when you clicked on it, it will show exactly the same thing as desired. She requested me that we check if it will work, it worked but has a little problem. The background and other images are missing as we clicked on each web pages. Something's wrong but I don't know how to solved it because I'm not familiar with HTML programming. I just tried learning a few days ago. 

I want to help the girl solved it so we started to analyze the problem. I don't think we could make it right since it was recorded already in the cd. And theres no way to correct unless to burn another copy or to correct the project before burning it again. She said that the location might be the problem but I don't think it was.

Silently, I started to analyze the problem. I tried to review those web pages I copied from the internet. I found out that each time I saved a web pages, there's a corresponding folder containing all the files necessary for a web pages to work. And when you delete the folder containing those files, the web pages disappear too. I noticed too, that when I save it as web page complete it will work compared to HTML only. So we tried it that way and the homepage work but not the sub pages. I assume that there was a problem with HTML programming and not with the way I burned it.

Anyway, I was a little bit challenged by that project and want to find it myself what went wrong. So I guess I had to do more research and study more about HTML programming. Thanks to that girl.
