Some days ago I received an e-mail from LinkedIn which offers a new LinkedIn app (LinkedIn Job Search). I was surprised by the footer bar which was sticking to the bottom of the screen.

I'm very curious how to build this! Google didn't help me any further and I didn't see it before. Can anyone help me further?
