Ionic Tabs
Ionic Tabs is a collection of important directives for creating a tab-based layout for a section of your mobile app. We have already seen how the tabs directive is used in the tabs starter template.
Ionic Tabs is a collection of two directives and one service. The directives are <ion-tabs> used to define the collection or group of tabs, and the <ion-tab>, directive, which is used to define a specific tab. The service $ionicTabsDelegate is used to control the tabs from JavaScript in order to select a specific tab.

It provides a multi-tabbed interface with a set of tabs and multiple views that can be switched. The tabs CSS classes are used to set the styling of the tabs group. The class name tabs should be used along with the following classes for specific styles:
The <ion-tabs> directive has one attribute that enables you to pass a custom handle for the delegate as shown in the following table:
The <ion-tab> directive
Inside the <ion-tab> directive, we can use one or multiple <ion-tab> directives. The tab content can be included in the <ion-tab> directive, which will be shown only when the specific tab is selected. Each <ion-tab> has its own navigation history and should include its own named <ion-nav-view>.
The following is the usage of this directive:
<ion-tab title="Custom Tab" icon="ion-star" href="#/book/favourites" on-select="goToFavourites()" on-deselect="unsetFavourites()"> </ion-tab>
The important attributes available on the <ion-tab> directive and their functions is outlined in the following table:
