I built an email featuring an interactive Magic 8 Ball for Email on Acid. The 8 Ball uses a technique to animate a series of labels over a button to achieve a “pseudo” random outcome when the user presses the button.

Here’s the article that explains the details behind the email: How to Build an Interactive Magic 8 Ball for Email

You can send yourself an example of the email here.

I also created a simplified version demonstrating the concept in this CodePen.

Hint: Click on the detective on the top right to see the innerworkings of the design.
