Changing styles on one page only

Hi, I am having a little bit of trouble doing this. Essentially, I want a home page different from all other pages. I want to edit the styles on this page only and not have it affect the rest of my website. Is there any way of doing this? I want a background image, big text in the center, and the navigation bar at the top-center (about text in middle of page). Every time I edit the style, of course, the rest of the website is changed as well.

you need to use custom css for this

If you can describe in detail, we can take a look.
