Repositioning Background Video on homepage

Site URL: http://www.jakemitchellmiller.com

Hi I'm having a similar issue - I have tried various provided codes from different forums with the correct section ID's and haven 't found any luck. In theory I would love to keep the same background video for the mobile version of my site with the frame repositioned so faces aren't cropped out. But if this is not possible I'd be fine with just a static image on mobile.

Please advise.

Try adding this code to Home > Design > Custom CSS

@media screen and (max-width:640px) {
body.homepage .Parallax-item:first-child iframe {
    width: 100% !important;
    height: auto !important;
    left: 0 !important;
}
section#welcome {
    min-height: unset;
    height: 200px;
}
body.homepage .Parallax-item:first-child figure {
    bottom: 0 !important;
}
}
