How to get only background image to show on mobile site and video only on desktop background?

Site URL: https://www.aleeyadesignstudio.com

Hi, I have a video for my landing page background that doesnt play well on the mobile. I've tried codes that people have suggested on other posts but they just show up as the code in the header.. I have set a fallback image which I want for it to show on mobile viewing only. Please help!

You can try adding to Home > Design > Custom Css

@media only screen and (max-width: 767px) {
  section[data-section-id="6202215effc997353c892dc5"] .sqs-video-background-native__video-player {
    display: none;
  }

  section[data-section-id="6202215effc997353c892dc5"] .sqs-video-background-native__fallback-image--hidden {
    opacity: 1;
  }
}

Let me know how it works on your site

Thank you so much! It worked! 
Would you also know how to get black and white images to show in a portfolio grid of images and the colour with text to only show when mouse is hovered over?
