Hello,
A white line is appearing underneath videos I uploaded to my Shopify store on the “Enterprise” theme - www.shayrdair.com - particularly on mobile (see below).
Could really use some help! 
I can’t remember exactly, did I help you in the past? 
Anyway. Add this to your section’s custom CSS
video-component > video {
height: calc(100% + 2px)
}
And that should fix it. Let me know if it doesn’t.
This worked!! Thank you very much!
