I figured it out! This is the code I used to answer my question, in case anyone else needs this. Thank you anyways.
.portfolio-hover {
min-height: 0% !important;
}
.portfolio-hover-display {
min-height: unset !important;
height: 100% !important;
padding: 0 !important;
}
.portfolio-hover-item {
border-top: 1px solid white;
overflow-x: hidden !important;
overflow-y: hidden !important;
width: 100%;
padding-left: 100vw;
padding-right: 100vw;
box-sizing: content-box;
}
