Is it possible to create a greeting card that opens online like a book?

This is really for a trifold square card and I can't seem to find anything that allows me to do this...

What about Page Transititons? Window>Pages> (click the menu "3 lines upper right"), go to Page Attributes>Transitions and choose the one you want.

You could also go to window>interactivity and select some options from there.

You could *mimic* the effect using InDesign's animation tools. Then publish using Publish Online. Here are some examples of things you can do using these tools. None exactly as you describe, but hopefully it will give you an idea of the potential.
