kidturtle,
Welcome to the board. It's good that you want to learn how to build websites from the very beginning. You've come to the right place to learn what you need to get started. I will tell you that just like any other project, in order to be efficient and successful you'll have to be determined and really dig into the information here.
If you haven't already seen it, Lisa has a wonderful website that shows people how to build websites from scratch.
You can view it here:

Keep in touch with the board and ask your questions and we'll do what we can to help you.
