wix form does not load

Hello. I am hoping someone can help me. My wix site looks different on every browser, despite the fact that I have every element inside a strip. On numerous pages it crates a horizontal scroll bar at the bottom of my page. It does not do this on the computer I am working from but when I call the site up on other computers the screen is stretched and looks a mess on different screens. Wix has not been able to help me fix this. I don't know how to code anything as I am new to designing my wix website but sure could use some help. I thought that anything inside a strip was supposed to be responsive. The site is https://bill0782.wixsite.com/mysite
