Password Protect Page Layout Adjustment

We have a page that is password protected. Here is a link. http://www.mylivinghistory.org/rplw/. As you can see the there needs to be some space between the submit button and the where you type in the password. Also, is there a way to make the black area which should be way down the page because it is the footer. Is there a way to put more white space back between the submit button and the footer? Thank you.
