Why does my Venture Theme website show a black section in landscape mode?

My website link is https://www.naturewoodfloors.com/. After loading the site on mobile if I rotate the mobile to the landscape mood its showing a black section to the right and the scroll bar. This is a responsive issue I think.

Please add the following code at the bottom of your assets/theme.scss.liquid file.

html {
    background-color: #f7f7f7!important;
}

Thanks!
