Scroll inside of a fixed sidebar

Question

I have a fixed sidebar on the left of my site with content that has too much content to display on the screen. How can I make that content scrollable while still allowing th

Answer 1

I had this same issue and fixed it using:

.WhateverYourNavIs {
      max-height: calc(100vh - 9rem);
      overflow-y: auto;
 }

This sets the max height for your nav in a way that is responsive to the height of the users browser and then gives it a scroll when it needs it.

Answer 2

Set the top and bottom to 0, so that the sidebar is exactly the same height as the viewport:

#leftCol {
    position: fixed;
    width: 150px;
    overflow-y: scroll;
    top: 0;
    bottom: 0;
}
