Float message blocks mobile menu button even after close

When the floater message is closed, it does a nice animation where it scrolls down a bit and opacity goes to 0. However, the #message_box element is still on the page and blocks the menu button in the new mobile layout.

I believe that the element should be set to display: none; when dismissed. If the same visual effect is desired, something like could be added at the end of the #close_message click() function.

I know I have seen other threads considering bigger overhauls to the floater for mobile. I think this change would help to the extent it remains as is. Thanks!

Let me chew on this a bit... I need to make sure I understand what you are talking about for the improvement.
