How to fix the position of one element in flux? - css

Question

I have left side side bar and right side content. I used flex box to separate them. It works fine. But when scrolling the content the side bar on the left side also scrolls along with the content. I wan to fix the side bar in the same position.
This is the Side bar html
<nav id="sidebar">
<ul class="list-unstyled components">
<li>
<a href="#usersMenu" data-toggle="collapse" aria-expanded="false" class="dropdown-toggle"
>Users</a
>
<ul class="collapse list-unstyled" id="usersMenu">
<li>
<a routerLink="/admins">Admins</a>
</li>
<li>
<a routerLink="/sellers">Sellers</a>
</li>
<li>
<a routerLink="/customers">Customers</a>
</li>
<li>
<a routerLink="/delivery-boys">Delivery Boys</a>
</li>
</ul>
</li>
<li>
<a routerLink="/shop/categories">Categories</a>
</li>
<li>
<a routerLink="/shop/brands">Brands</a>
</li>
<li>
<a routerLink="/shop/products">Products</a>
</li>
<li>
<a routerLink="/shop/orders">Orders</a>
</li>
<li>
<a routerLink="/shop/deliveries">Deliveries</a>
</li>
</ul>
</nav>
This is the Side bar css
a,
a:hover,
a:focus {
color: inherit;
text-decoration: none;
transition: all 0.3s;
}
#sidebar {
min-width: 250px;
max-width: 250px;
background: #1d5ea8;
color: #fff;
transition: all 0.3s;
height: 100%;
margin-top: 56px;
}
#sidebar.active {
margin-left: -250px;
}
#sidebar ul.components {
padding: 20px 0;
border-bottom: 1px solid #1d5ea8;
}
#sidebar ul p {
color: #fff;
padding: 10px;
}
#sidebar ul li a {
padding: 10px;
font-size: 1.1em;
display: block;
}
#sidebar ul li a:hover {
color: #7386d5;
background: #fff;
}
#sidebar ul li.active > a,
a[aria-expanded='true'] {
color: #fff;
background: #1d5ea8;
}
a[data-toggle='collapse'] {
position: relative;
}
.dropdown-toggle::after {
display: block;
position: absolute;
top: 50%;
right: 20px;
transform: translateY(-50%);
}
ul ul a {
font-size: 0.9em !important;
padding-left: 30px !important;
background: #1d5ea8;
}
This is the app-component.html
<div class="wrapper">
<app-side-nav-bar *ngIf="checkLogin()"></app-side-nav-bar>
<app-horizontal-nav-bar *ngIf="checkLogin()"></app-horizontal-nav-bar>
<div id="content">
<router-outlet></router-outlet>
<app-footer *ngIf="checkLogin()"></app-footer>
</div>
</div>
This is the wrapper and content css
.wrapper {
display: flex;
width: 100%;
align-items: stretch;
}
#content {
width: 100%;
min-height: 100vh;
transition: all 0.3s;
}

You have to set #content to overflow-y: auto so that the scroll bar scrolls inside the content section and not the whole body.
