Question

Ionic4 项目中我们可以使用 Ionic4 浮动按钮组件 ion-fab 对项目进行布局。

ion-fab 官方文档地址：https://ionicframework.com/docs/api/fab

Fabs are container elements that contain one or more fab buttons. They should be placed in a fixed position that does not scroll with the content. Fab should have one main fab-button. Fabs can also contain fab-lists which contain related buttons that show when the main fab button is clicked. The same fab container can contain several fab-list elements with different side values.
