Styling ionic 2 toast

Answer 1

I tried all above, still didn't work, therefore I come across a new solution, you need cssClass outside of page css declaration:

let toast = this.toastCtrl.create({
          message: msg,
          duration: 3000,
          position: 'bottom',
          cssClass: 'toastcolor'
        });

post-list.scss like this

page-post-list {

}
.toastcolor .toast-message {
    background-color:skyblue;
}
