How to create a sticky navigation bar that becomes fixed to the top after scrolling

I was searching for this very same thing. I had read that this was available in Bootstrap 3.0, but I was having no luck in actually implementing it. This is what I came up with and it works great. Very simple jQuery and Javascript.

Here is the JSFiddle to play around with…

The solution is very similar to other solutions on the web and StackOverflow. If you do not find this one useful, search for what you need. Goodluck!

Here is the HTML…

<div id="banner">
  <h2>put what you want here</h2>
  <p>just adjust javascript size to match this window</p>

  <nav id='nav_bar'>
    <ul class="nav_links">
      <li><a href="">Sign In</a></li>
      <li><a href="">Blog</a></li>
      <li><a href="">About</a></li>

<div id='body_div'>
  <p style="margin: 0; padding-top: 50px;">and more stuff to continue scrolling here</p>

Here is the CSS…

html, body {
  height: 4000px;

.navbar-fixed {
  top: 0;
  z-index: 100;
  position: fixed;
  width: 100%;

#body_div {
  top: 0;
  position: relative;
  height: 200px;
  background-color: green;

#banner {
  width: 100%;
  height: 273px;
  background-color: gray;
  overflow: hidden;

#nav_bar {
  border: 0;
  background-color: #202020;
  border-radius: 0px;
  margin-bottom: 0;
  height: 30px;

//the below css are for the links, not needed for sticky nav
.nav_links {
  margin: 0;

.nav_links li {
  display: inline-block;
  margin-top: 4px;

.nav_links li a {
  padding: 0 15.5px;
  color: #3498db;
  text-decoration: none;

Now, just add the javacript to add and remove the fix class based on the scroll position.

$(document).ready(function() {
  //change the integers below to match the height of your upper div, which I called
  //banner.  Just add a 1 to the last number.  console.log($(window).scrollTop())
  //to figure out what the scroll position is when exactly you want to fix the nav
  //bar or div or whatever.  I stuck in the console.log for you.  Just remove when
  //you know the position.
  $(window).scroll(function () { 


    if ($(window).scrollTop() > 550) {

    if ($(window).scrollTop() < 551) {
