Responsive Youtube Videos & Tables

I have a website located @ http://futuristicedm.net/ where I have 3 videos @ the top of the home page. This layout is nice on a desktop or tablet, but if viewed from a mobile device such as a cellular phone the videos can only be viewed if titled landscape. I wanted to know if there was an option that I could make these videos automatically stack on top of each other for those who browsed on mobile devices. Thanks ahead of time
