I created a hero: style-1 on my website called Main-Roberto-Hero-1. I put an image in the background image. When I look at it on a desktop it looks great. When I look at it on a tablet or smartphone the image is shifted to the right. I fiddled with it until it looked okay on the phone and tablet, now it's chopped off on the top and bottom when I view it on a desktop. What am I doing wrong? What do I need to do to the image, or the hero setting, for this to work on any form factor?
