Custom CSS for a different item to appear in mobile view versus desktop view

Hi there, 

I am aware now that autoplay videos might not be displayed on mobiles due to settings. 

I would like my desktop version to display an autoplay video, but mobile to display an image instead. 

Could you please help me with the code and instructions for this? 

Thank you. 

Hi,

You can add 2 sections: video section, image, then we can give code to show video section on desktop, show image section on mobile
