I want to create fixed sidebar but scroll does not work

Stack Overflow Asked by nav on December 11, 2020

I am using grid layout and the scroll does not work on sidebar if I set the position to fixed it changes the layout and does not work properly when screens shrinks. But if I do not set the position fixed then the sidebar is not fixed. I tried to change the margin padding and different position to fix it but no luck
how can I solve this problem.
Thanks in Advance

You have no content inside your , that is why it's not scrolling with the page.

I provided min-height to .main-doc so it started scrolling.

You will not have to provide any min-height if you have sufficient content.

 .wrapper{
        display:grid;

Add position: fixed to navbar and add more elements to see the effect.

    margin:0;
    padding:0;
    top:0;
    overflow-y:auto;
    position: fixed; // Added this
 }
.navbar ul{
list-style-type:none;
font-size:1.2em;
display:flex;
flex-direction:column;

I think the problem in (height:100%;), replace it with (min-height: 100%;) or set it to value in pixels (height: 100px;).
