Move Menu Bar to Bottom + Make Sticky / Angular UI Problem - html

Question

On Angular UI one page app, there is an overhead menu, side bar menu, and I am trying to implement a bottom menu bar.
In the component itself I have it as position: sticky:
#import '../../../styles/variables';
.bottom-bar {
position: sticky;
background-color: white;
overflow: hidden;
height: 65px;
width: absolute;
}
.menu-button {
width: 100%;
height: 100%;
&__text {
font-family: $font-sarabun, 'sans-serif';
font-weight: 500;
font-size: 16px;
letter-spacing: 0.05em;
#media (max-width: 992px) {
display: none;
}
}
}
.mat-button,
.mat-icon-button,
.mat-stroked-button {
color: inherit;
background: 0 0;
border-radius: 0;
vertical-align: 0px;
}
.menu-button-import {
margin-top: 15px;
float: left;
margin-left: 20px;
background-color: #ffffff;
color: $color-menu-item;
font-weight: 500;
min-width: 100px;
font-size: 18px;
letter-spacing: 1px;
position: relative;
border: 1px solid grey;
border-radius: 5px;
&__text {
font-family: $font-sarabun, 'sans-serif';
font-weight: 500;
font-size: 16px;
letter-spacing: 0.05em;
#media (max-width: 992px) {
display: none;
}
}
}
.menu-button-save {
margin-top: 8px;
background-color: #ffffff;
color: $color-menu-item;
font-weight: 500;
min-width: 100px;
font-size: 18px;
letter-spacing: 1px;
position: relative;
border: 1px solid grey;
border-radius: 5px;
}
.menu-button-export {
margin-top: 15px;
margin-left: 10px;
margin-right: 20px;
background-color: #0693e3;
font-weight: 500;
min-width: 100px;
font-size: 18px;
letter-spacing: 1px;
position: relative;
border: 1px solid grey;
border-radius: 5px;
color: white;
&__icon {
color: white;
}
}
In the app html the bottom-bar component is also sticky:
.bottom-bar{
position: sticky;
top: 50px;
}
However, when I run the app I am having to scroll down to see the bottom bar. When I zoom out I notice that the bottom bar is not at the bottom of the page.
I am trying to make it so that the bottom bar stays fixed at the bottom of the page even when scrolling.
Hopefully I described the problem clearly enough. Please advise on how I can fix the problem. Thanks.
