One of the little things I like about Android is the “toast.” If you are not familiar with the toast, it is the little transparent notice you get that operations are done. The best example is the toast that tells you how long you will have to sleep before your alarm goes off. (Pictured here.)
I really like the concept. It usually short-circuits the whole item editing process.
- Click save button.
- Get feedback that item has been saved.
- Manually go back to previous screen.
- Click save button & go back & get feedback.
So the first thing I have to do is apply the transition.
You’ll notice a couple of things here. One the syntax for the transform is pretty simple:
[browser css keyword]: [property to animate] [duration] [easing method]
Once you do that, the rest is really simple. Basically, all you have to do is change the value for the property you have added a transform to, and the browser takes care of the rest. So to fade out my toast, I set the opacity to 0. That’s it.
See the demo.
Why do I like this:
- I always prefer doing visual things in CSS.
- CSS transitions will be hardware accelerated on environments that support doing so.
Now, I have to tell you there are caveats:
- It doesn’t work in IE
- I’m sure someone who knows more than I will put more in the comments
But it does work within the mobile browsers I tested on iOS and Android, which means I’m free to use this in my PhoneGap application.
