I managed to get to the buttons by zooming out. Couldn't see them by default (Chrome on a Retina Macbook Pro). Tried scrolling and clicked every item visible too before figuring it out, ha.
You don't need any tricks for the sticky footer. Just use position: fixed on the footer and add a padding-bottom to the body for the same height as the footer. In absolutely ancient browsers it will simply show the footer at the bottom when you scroll there.
