ion-slides

The Slides component is a multi-section container. Each section can be swiped or dragged between. It contains any number of Slide components.

Adopted from Swiper.js: The most modern mobile touch slider and framework with hardware accelerated transitions.

Custom Animations

By default, Ionic slides use the built-in slide animation effect. Custom animations can be provided via the options property. Examples of other animations can be found below.
