Thanks it worked! I want the background image to be centered. How do I do that?

body
{
background-image: url(images/yourimage.fileextension);
background-repeat: repeat;
background-attachment: fixed;
background-position: center;
}

Are some CSS examples to modify the background image.

I'm really new to all of this, and I'm trying to add a background image to Greek Yogurt as well... I figured out how to do so on Plain Yogurt, but adding a css in the Greek theme does not make it appear on the site.

Could you explain how to find the place where you modify it manually?

and maybe explain which areas are supposed to say what so that I know what text to add in so that my images show?

Thanks!
Sorry I know I'm super new
