Getting a user to subscribe to a website’s newsletter mailing list is always the most challenging part. IMO, the key is where you position the call-to-action form. Then there’s the UI and UX of the newsletter form itself. When user decides to subscribe, we need to make sure the process is flawlessly smooth and simple. Claudia Romano and her team started experimenting with some subtle CSS3 animations to enrich the newsletter form while the user is interacting with it. You can see how the process improves user experience greatly through fluid animation and minimal interface.
