How To Hide Navbar on Scroll Down

Step 1) Add HTML:

Create a navigation bar:

Example

<div id="navbar">
  <a href="#home">Home</a>
  <a href="#news">News</a>
  <a href="#contact">Contact</a>
</div>

Step 2) Add CSS:

Style the navigation bar:

Example

#navbar {
    background-color: #333; /* Black background color */
    position: fixed; /* Make it stick/fixed */
    top: 0; /* Stay on top */
    width: 100%; /* Full width */
    transition: top 0.3s; /* Transition effect when sliding down (and up) */
}

/* Style the navbar links */
#navbar a {
    float: left;
    display: block;
    color: white;
    text-align: center;
    padding: 15px;
    text-decoration: none;
}

#navbar a:hover {
    background-color: #ddd;
    color: black;
}


Step 3) Add JavaScript:

Example

/* When the user scrolls down, hide the navbar. When the user scrolls up, show the navbar */
var prevScrollpos = window.pageYOffset;
window.onscroll = function() {
  var currentScrollPos = window.pageYOffset;
  if (prevScrollpos > currentScrollPos) {
    document.getElementById("navbar").style.top = "0";
  } else {
    document.getElementById("navbar").style.top = "-50px";
  }
  prevScrollpos = currentScrollPos;
}
