How to solve the mysterious white space at the bottom of the page in CSS

I'm trying to build a simple webpage using Bootstrap and D3, but I don't know how to get rid of all the whitespace at the bottom. I want to get rid of it.

I tried setting the min-height of body and html to 100%, but nothing worked. My code is here: https://github.com/eelegiap/thesis-code/tree/main/search

body {
    padding-left: 3vh;
    padding-top: 3vh;
    padding-bottom: 20px;
}

#searchCol {
    padding-left: 6vh
}

form {
    width: 25%
}

#results {
    padding-right: 10vh;
}

#resultsContainer {
    max-height: 30%;
    overflow-y: auto
}
.result {
    padding-left: 4vh;
}
.poemResult {
    cursor: pointer;
    border-radius: 10px;
    padding-left: 10px;
    padding-top: 5px;
}

#poemContainer {
    max-height: 30%;
    overflow-y: auto;
}
#poemMeta {
    padding-top: 10vh;
    padding-left: 15vh;
    padding-bottom: 5vh
}
#poemTxt {
    padding-left: 15vh;
    padding-bottom: 10vh;
}

.input-group {
    max-width: 75%;
    padding-bottom: 5vh
}

/* Tooltip text */
.titleTooltip .tooltiptext {
    visibility: hidden;
    position: absolute;
    text-align: left;
    width: fit-content;
    height: fit-content;
    padding: 2px;
    padding-right: 15px;
    font: 12px sans-serif;
    background: #e5ffff;
    border: 1px solid gray;
    border-radius: 8px;
    pointer-events: none;

    z-index: 1;
}

.titleTooltip:hover .tooltiptext {
    visibility: visible;
}

.token mark {
    display: contents;
}

input,
.dropdown-toggle {
    box-sizing: border-box;
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
}

.searchBar {
    min-height: 50px
}

#search {
    background-color: lightsteelblue;
}
