How TO - Off-Canvas Menu

Learn how to create an off-canvas menu.

Create an Off-Canvas Menu

Step 1) Add HTML:

Example

<div id="mySidenav" class="sidenav">
<a href="javascript:void(0)" class="closebtn" onclick="closeNav()">×</a>
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Clients</a>
<a href="#">Contact</a>
</div>


<span onclick="openNav()">open</span>


<div id="main">
...
</div>

Step 2) Add CSS:

Example

/* The side navigation menu */
.sidenav {
  height: 100%; /* 100% Full-height */
  width: 0; /* 0 width - change this with JavaScript */
  position: fixed; /* Stay in place */
z-index: 1; /* Stay on top */
top: 0;
left: 0;
  background-color: #111; /* Black*/
  overflow-x: hidden; /* Disable horizontal scroll */
  padding-top: 60px; /* Place content 60px from the top */
  transition: 0.5s; /* 0.5 second transition effect to slide in the sidenav */
}

/* The navigation menu links */
.sidenav a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
  display: block;
  transition: 0.3s;
}

/* When you mouse over the navigation links, change their color */
.sidenav a:hover {
  color: #f1f1f1;
}

/* Position and style the close button (top right corner) */
.sidenav .closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}

/* Style page content - use this if you want to push the page content to the right when you open the side navigation */
#main {
transition: margin-left .5s;
padding: 20px;
}

/* On smaller screens, where height is less than 450px, change the style of the sidenav (less padding and a smaller font size) */
@media screen and (max-height: 450px) {
.sidenav {padding-top: 15px;}
.sidenav a {font-size: 18px;}
}

Step 3) Add JavaScript:

Off-Canvas Menu

/* Set the width of the side navigation to 250px and the left margin of the page content to 250px */
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
}

/* Set the width of the side navigation to 0 and the left margin of the page content to 0 */
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
}

The example below also slides in the side navigation, and pushes the page content to the right, only this time, we add a black background color with a 40% opacity to the body element, to "highlight" the side navigation:

Off-Canvas Menu w/ opacity

/* Set the width of the side navigation to 250px and the left margin of the page content to 250px and add a black background color to body */
function openNav() {
  document.getElementById("mySidenav").style.width = "250px";
  document.getElementById("main").style.marginLeft = "250px";
  document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}

/* Set the width of the side navigation to 0 and the left margin of the page content to 0, and the background color of body to white */
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
  document.getElementById("main").style.marginLeft = "0";
  document.body.style.backgroundColor = "white";
}
