Footer adjust to bottom of screen regardless of content

Hi, new user here to the Adonis Pro theme. I am using a full screen background video on my site as a landing page and having difficulty spacing out the other elements on the page. Primarily, the footer. I would like it placed right above the player controls at the bottom of the screen but haven't found a way to do this yet. I basically want NO content on the front page except for Company Logo Modern Menu Full Screen bg video playing (using YTPlayerPlus plugin for that) and a thin footer at the bottom. Can you please help? Thank you site is www.purpleceiling.com
