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.
Create a Snackbar
Step 1 - Add HTML:
Example
<!-- 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:
Example
/* 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) */
#snackbar.show {
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:
Example
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)
}
