Referencing a hosted CSS file in an Ionic app

Hi,

This would be a solution to a problem I’m encountering for adding styles which customers can ask us to add.

This file would be hosted and always be live, my question is when the login they have to be online so that solves getting the CSS file, but when they’re offline does a cached version of the CSS stored locally on the phone whether it be iOS/Android. Also would the CSS file try to load everytime I change states, or everytime I launch the application.

Thanks for any insight!

Mat.
