Following Directions

I helped out in the Memorial Library today because a class was visiting. They were going to see the whole library, but spend half an hour in the Memorial Library learning about WWII airplanes and making paper airplanes. They are learning about planes in school right now. They are also learning about following a set of instructions, so the directions we had for a specific paper airplane worked out well. I'll be going in again the next two days to do the same thing!

I did some more work on the website today. Starting fresh helped. Here is my problem:

For simple stuff I can find really straightforward instructions. How do you change the background color? There is a page in my book that tells you how to do exactly that. But now that I'm trying to do more complicated stuff, there aren't specific instructions. How do I get my YouTube video exactly where I want it on the screen without fixing it a certain distance from the edge? Turns out, it is possible but there isn't a page in the book on how to do it. There is a page in the book on how to give a division margins. I had to figure out myself that putting a large margin on just the left would move the video to the right of my navigation bar. I think the cavemen had it right. When you paint a buffalo on a certain spot on the wall, that buffalo is going to be on that spot on the wall. It doesn't need margins to make it stay there.
