How to make use of it:

1. Put each jQuery library and the jQuery sidebarFix.js script within the HTML web page.

<script src="//code.jquery.com/jquery.min.js"></script>
<script src="jquery.sidebarFix.js"></script>

2. Create a sidebar and make it sticky inside a particular container.

$('.jq_sidebar_fix').sidebarFix({
  frame: $('.container')
});

3. Set the top offset in instances of the place you’ve got a sticky header nav.

$('.jq_sidebar_fix').sidebarFix({
  frame: $('.container'),
  topBuffer: 100
});

4. Fix the position concern where the sidebar is nested within the container.

$('.jq_sidebar_fix').sidebarFix({
  frame: $('.container'),
  force: true
});
