Parallax background image fit div

Question

I'm trying to create a parallax background as a separator for a site. The background image seems to be only taking up about half of the size it should be with a strange white border all around it. I can't seem to find anything in my code that might be causing this and no matter what I do I either have the border, or scroll bars on the inside div. I just need the background image to fit the space of the div to make a scrolling parallax in that section.

I've tried overflow:hidden playing with various height/width combinations including calc(100vh * 2) to make the image larger. The only thing it seems to do is change the image in the container it appears in (almost like a sub container but there isn't a sub-container on it). I've also played with the transform, transform-origin, perspective, scale, and anything else I could find on google and here.


html, body {
    height: 100%!important;
    margin: 0px;
    padding: 0px;
}

input, select, textarea {
    box-shadow: inset 0 2px 4px hsla(0, 0%, 0%, 0.13);
}

.ico {
    width: 50px!important;
    height: 50px!important;
}

nav {
    position: fixed!important;
    z-index: 999;
    width: 100vw;
}

.content_head {
    background-color: aqua;
}

.content_about {
    background-color: blueviolet;
}

.content_spacer {
    opacity: 0;
    height: 50vh;
}

.back_spacer {
    opacity: 0;
}

.back1 {
    background-image: url("images/IMG_1164.JPG");
    background-clip: border-box;
    background-size: cover;
    height: 100%!important;
    width: 100%!important;
    min-height: 100%!important;
    min-width: 100%!important;
}

.back-group {
    max-height: 75vh!important;
}

.container-fluid {
    padding: 0!important;

}

        </div>

Strictly speaking, I suppose it isn't actually a border, but more that the background image is smaller than the DIV element as a whole.

there is no border after placing the right image path and scroll comes because of your .parallax class overflow-y: auto. — Nisharg Shah
There's a horizontal and vertical scroll inside the div element that I want to get rid of. What do you mean by "the right image path"? — sylphaxiom
the right image path I don't see any border after placing the correct image path in img tag and can you take a screenshot and show us, which border you talking about. Do you want to remove all your scrollbar from your code? — Nisharg Shah
so your border problem is solved and now you want to cover your image in div? as your screenshot says there is image between content base 1 and 2 but your code says different, please provide full code^_^ — Nisharg Shah
