Angular2 Page Transition Animation Example

In this example, we will see how page transition animation can be achieved in Angular 2 using ng-animate . Since it is really just about css, I am not going to separate the example into Javascript and Typescript.

Page 1 is a very basic component. Css styles are embeded in template file in this example. If you prefer to have it in a css file, you can use styleUrls in the component metadata.


This is the template for page 1 component with styles embedded. The animation effect is horizontal flip when page 1 is entered. I didn’t bother setup ng-leave because ng-leave is not working properly as of version 2.0.0-beta.6.



This is the template for page 2 component with styles embedded. The animation effect is rotate when page 2 is entered.


This is the root component.

    You can explain the :host part please?

    • Wayne Hong

      Long story short, whenever a component is created, Angular put the template into a root element to emulate Shadow Dom and scoped styles that sort of stuffs. When a component is entering the view, Angular checks if the element has ‘ng-animate’ in the class attribute of the root element (host) or not, if yes, it then adds ng-animate related classes to it. So, what we need to do here is to define animation css for the host element. And that’s when :host come into play. Angular actually added some attributes to the component when it is rendered, and also when Angular sees :host on the styles, it will rewrite the style to the head of the html with proper selectors to only match that particular component.

      Hope this answers your question. feel free to let me know if not. :)

    Very useful thanks, but there is a way to animate also the leaving page? ng-leave class is not working for me, and the leaving page is just disappearing in 0ms

    Can I put :host() styling into a standalone css file? Seems Angular are not applying it to component

    • Wayne Hong

      You surely can. Have you tried put them into a css file and use styleUrls to reference it?

    How about RC3? =)

  • Is this for the default angular router only, or will it work with ui-router-ng2 too? I’m using ui-router and it doesn’t seem that the ng-enter classes are being added at all.
