Create an Off-Canvas Menu
Step 1: Create index.html and implement below code.
<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>
<div id="main">
<div class="text-center">
<h1 id="color" style="color: tomato">How To Create An Off Canvas Menu Using CSS And JavaScript</h1>
</div>
<h2>Sidenav Push Example</h2>
<p>Click on the element below to open the side navigation menu, and push this content to the right. Notice that we add a black see-through background-color to body when the sidenav is opened.</p>
<span style="font-size:30px;cursor:pointer" onclick="openNav()">☰ open</span>
</div>
Step 2: Now implement CSS code to style nav bar
<style>
body {
font-family: "Lato", sans-serif;
transition: background-color .5s;
}
.sidenav {
height: 100%;
width: 0;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
transition: 0.5s;
padding-top: 60px;
}
.sidenav a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
transition: 0.3s;
}
.sidenav a:hover {
color: #f1f1f1;
}
.sidenav .closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}
#main {
transition: margin-left .5s;
padding: 16px;
}
@media screen and (max-height: 450px) {
.sidenav {padding-top: 15px;}
.sidenav a {font-size: 18px;}
}
</style>
Step 3: Now Implement java script to work off canvas menu.
<script>
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
document.getElementById("color").style.color = "white";
document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft= "0";
document.body.style.backgroundColor = "white";
}
</script>
