Random white line on mobile site

I'm currently working on a website that looks great on desktop but shows a random white line on the mobile version. I've attached an image below. I've tried coding it out, playing with site colors, and readjusting page layout but can't get rid of the line even when I turn off the option for a page divider. 

Current code being used in CSS is 

@media screen and (max-width:767px) {
body#collection-62190ed89b8bb57737b08465 br {
    display: none;
}
}

Any help is appreciated!

body {
	background-color: #757264;
