There's nothing like trying it to find out.

If you set the same style property on the same element (in this case
the document body), then yes, the second one overwrites (replaces) the
first. It's just like setting the property of an object (in fact, it
*is* setting the property of an object).
BTW, it's OT, but take out that semicolon. Semicolons are used in CSS
blocks to mark the end of a style definition, they are not part of the
style value. Here you're giving the style value.
