How TO - Snackbar / Toast

Learn how to create a snackbar / toast with CSS and JavaScript.

Snackbar / Toast

Snackbars are often used as tooltips/popups to show a message at the bottom of the screen.

Click on the button to show the snackbar. It will disappear after 3 seconds.

Some text some message..

Create a Snackbar

Step 1) Add HTML:


<!-- Use a button to open the snackbar -->
<button onclick="myFunction()">Show Snackbar</button>

<!-- The actual snackbar -->
<div id="snackbar">Some text some message..</div>

Step 2) Add CSS:

Style the snackbar and add animations:


/* The snackbar - position it at the bottom and in the middle of the screen */
#snackbar {
    visibility: hidden; /* Hidden by default. Visible on click */
    min-width: 250px; /* Set a default minimum width */
    margin-left: -125px; /* Divide value of min-width by 2 */
    background-color: #333; /* Black background color */
    color: #fff; /* White text color */
    text-align: center; /* Centered text */
    border-radius: 2px; /* Rounded borders */
    padding: 16px; /* Padding */
    position: fixed; /* Sit on top of the screen */
    z-index: 1; /* Add a z-index if needed */
    left: 50%; /* Center the snackbar */
    bottom: 30px; /* 30px from the bottom */

/* Show the snackbar when clicking on a button (class added with JavaScript) */ {
    visibility: visible; /* Show the snackbar */

/* Add animation: Take 0.5 seconds to fade in and out the snackbar.
However, delay the fade out process for 2.5 seconds */
    -webkit-animation: fadein 0.5s, fadeout 0.5s 2.5s;
    animation: fadein 0.5s, fadeout 0.5s 2.5s;

/* Animations to fade the snackbar in and out */
@-webkit-keyframes fadein {
    from {bottom: 0; opacity: 0;}
    to {bottom: 30px; opacity: 1;}

@keyframes fadein {
    from {bottom: 0; opacity: 0;}
    to {bottom: 30px; opacity: 1;}

@-webkit-keyframes fadeout {
    from {bottom: 30px; opacity: 1;}
    to {bottom: 0; opacity: 0;}

@keyframes fadeout {
    from {bottom: 30px; opacity: 1;}
    to {bottom: 0; opacity: 0;}

Step 3) Add JavaScript:

Use JavaScript to add the "show" class to the snackbar container with a click of a button:


function myFunction() {
    // Get the snackbar DIV
    var x = document.getElementById("snackbar")

    // Add the "show" class to DIV
    x.className = "show";

    // After 3 seconds, remove the show class from DIV
    setTimeout(function(){ x.className = x.className.replace("show", ""); }, 3000);
