Does the Normalize.css works fine if I add it as second css stylesheet or does it overwrite something?

as above mentioned i am not sure if my CSS file for resetting the default browser settings works fine if I add it as a second stylesheet link. Can u help me? Thanks

Normalize.css overwrites lots of things. That's the point of it.

Your rules might be written in such a way that they are more specific that the ones in normalize.css, or they might not.
