I created a sidebar div and a main content div. The main content contains a large amount of text, making the page scrollable. I want the sidebar to remain sticky while scrolling the page. I achieved this using position: sticky and a top value, but when I scroll, the sidebar sticks in the middle, and at the end of the scroll, it moves up. Why does this happen?

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

:root {
    --light-color: #EDF4F2;
    --dark-color: #31473A;
    --medium-color: #D3CAE2;
}

body {
    min-height: 100vh;
    min-width: 100vw;
    background-color: var(--light-color);
    display: grid;
    grid-template-columns: 20% 1fr;
    grid-template-rows: auto 1fr auto;
    grid-template-areas:
            'top-nav-area top-nav-area'
            'side-area main-area'
            'side-area main-area'
            'side-area footer-area';


}

.top-navigation {
    top: 0;
    position: sticky;
    grid-area: top-nav-area;
    background-color: var(--medium-color);
    padding: 2em;
}

.side-navigation {
    min-height: calc(100vh - 82px);
    top: 82px;
    position: sticky;
    align-self: start;
    grid-area: side-area;
    background-color: var(--dark-color);
    overflow-y: auto;


}

.main-content {
    grid-area: main-area;
}

.footer {
    grid-area: footer-area;
    background-color: var(--light-color);
}

Reset to default 2

In your case, just remove the min-width CSS property from the body tag because when text is more than screen height, the scrollbar appears, and min-width is considered the scrollbar width also. So content will overflow. Use the below code to fulfill your requirement.

Add the dummy text to the main content for the vertical scroll.

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

:root {
    --light-color: #EDF4F2;
    --dark-color: #31473A;
    --medium-color: #D3CAE2;
}

body {
    min-height: 100vh;
    background-color: var(--light-color);
    display: grid;
    grid-template-columns: 20% 1fr;
    grid-template-rows: auto 1fr auto;
    grid-template-areas:
        'top-nav-area top-nav-area'
        'side-area main-area'
        'side-area main-area'
        'side-area footer-area';
}

.top-navigation {
    top: 0;
    position: sticky;
    grid-area: top-nav-area;
    background-color: var(--medium-color);
    padding: 2em;
}

.side-navigation {
    min-height: calc(100vh - 82px);
    top: 82px;
    position: sticky;
    align-self: start;
    grid-area: side-area;
    background-color: var(--dark-color);
    overflow-y: auto;
}

.main-content {
    grid-area: main-area;
}

.footer {
    grid-area: footer-area;
    background-color: var(--light-color);
}
<body>
    <nav class="top-navigation">Navigation</nav>
    <aside class="side-navigation">side-navigation</aside>
