Introduction
Although Ionic has its own out-of-the-box default themes, you might want to even customize your app's look and feel further. There are several methods, as follows:
Change style sheet within Sass file
Detecting platform-specific type (iOS, Android, Windows) in JavaScript and applying custom classes or AngularJS conditions
Either of the above two methods should work, but it's highly recommended to apply customization in a Sass file before the app is built in order to achieve maximum rendering performance.
