Help using CSS on Noblesse color scheme
 

Using the custom CSS field I've manage to customize the default X-Cart 5 color scheme to something I like. However the default scheme is pretty bland so I'm trying to modify the Noblesse theme and a few things aren't working as I would expect them to. I am a complete noob to X-Cart 5 and CSS but I've done enough homework to do everything I wanted to the default scheme so hopefully someone here can help.

I want to remove the Noblesse background image and replace it with a solid color but using
.body {
background-color: #000000;
also tried it with and without background-image: none;
}

seems to only replace the top half of the pages background, as soon as you scroll down the background image returns.

I also want to change the sidebar to green (keeping the round edges), but I can't quite find the class for just the sidebar.

Finally I want to apply the same link colors from my CSS below, however adding the link color rules seems to have no effect on the Noblesse scheme.

Thanks in advance for any help you can provide.

Troubleshooting CSS is very hard without being able to view the page in question. Can you provide a link to your page?

Also, lets just deal with one CSS issue at a time. Makes it easier to digest.
