Floating Action Buttons (FABs) represent the primary action in an application. By default, they have a circular shape. When pressed, the button may open more related actions. As the name suggests, FABs generally float over the content in a fixed position. This is not achieved exclusively by using an <ion-fab-button>FAB</ion-fab-button>. They need to be wrapped with an <ion-fab> component in order to be fixed over the content.

If the FAB button is not wrapped with <ion-fab>, it will scroll with the content. FAB buttons have a default size, a mini size and can accept different colors:
