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>
