True or False ? ( about the true nature of scss )

Are the following statements correct? and if not, explain.

  1. When switching to a page using routing, the scss of the page will be used to set style.
  2. When opening a page as a modal (ModalController.create) the page’s scss is not being used.
  3. If you want to apply some style to a modal, all style data needs to be located in the global.scss file.

A question for Ionic developers is "how do you recommend to style a modal component/page?

Thank you,
