There's no wrapper for each post, so unless you want to use child selectors and do a hell of a lot of really unnecessary work with CSS, you can't.

Find out how WordPress does it's templates and add a div wrapper with a class.

 

Thank you creative I can add the div wrapper. I was not sure how to do it. Thanks for telling me.
