How can I make a video/text/picture be centered in my blog post?

Today's tip comes from Kathy at The Junk Drawer Blog.

To center video, text, pictures, etc.:

1. Go to the Edit HTML tab.
2. Find the item you'd like to center.
3. Type the following code before the item: <div align="center">
4. Type the following code after the item: </div>
5. Go to the Compose/WYSIWYG tab and check to see that the item is centered. Move the <div align="center"> or </div> code as necessary.
6. Click Save.

I've been typing at the beginning of the code and at the end, which has been working for me. I'm wondering if it makes any difference and if I should change the way I'm doing it. I'm such a novice when it comes to HTML.
