Style Product Page with CSS ("add to cart" below "quantity" selection)

Hey people!

Page: Product

I have multiple aesthetic problems with the product page and I can't style it within the editor. So I would like to style the following with CSS:

- "add to cart" should be below "quantity" selection
- "title" should be on same height with top of the picture
- text must be blue

Thank you!
Richard
