Learn How to Create a Snackbar / Toast with CSS and JavaScript

In today’s fast-paced world of web development, creating user-friendly and visually appealing interfaces is crucial. One element that can greatly enhance user experience is a snackbar or toast notification. These small pop-up messages provide quick feedback to users without disrupting their workflow. In this article, we will guide you through the process of creating a snackbar or toast using CSS and JavaScript. We’ll cover everything from the basic structure to advanced customization, ensuring you have a comprehensive understanding of the topic.

1. Introduction to Snackbar / Toast

Snackbar and toast notifications are compact pop-up messages that provide information or feedback to users. They are commonly used to display success messages, error alerts, or other relevant updates. The goal of these notifications is to communicate important information to users without causing disruption.

2. HTML Structure

To create a snackbar, we’ll need a simple HTML structure that will serve as the container for our notification. We’ll also include a close button to allow users to dismiss the notification.

<div class="snackbar" id="snackbar">
    Your message here
    <span class="close" id="close">&times;</span>
</div>

3. Basic CSS Styling

Let’s start with some basic CSS styling to make our snackbar visually appealing. We’ll position it at the bottom of the screen and style it with appropriate colors and fonts.

#snackbar {
    visibility: hidden;
    min-width: 250px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 5px;
    padding: 16px;
    position: fixed;
    bottom: 30px;
    left: 50%;
    transform: translateX(-50%);
    z-index: 1;
}

4. Adding JavaScript Functionality

Next, let’s add JavaScript functionality to show and hide the snackbar when needed. We’ll create a function to display the snackbar and another function to close it.

// Display the snackbar
function showSnackbar(message) {
    var snackbar = document.getElementById("snackbar");
    snackbar.innerHTML = message;
    snackbar.style.visibility = "visible";
    setTimeout(function () {
        snackbar.style.visibility = "hidden";
    }, 3000); // Hide after 3 seconds
}

// Close the snackbar
document.getElementById("close").addEventListener("click", function () {
    document.getElementById("snackbar").style.visibility = "hidden";
});

5. Animation Effects

To make our snackbar appear with a smooth animation, we can add a CSS transition effect. This will create a fade-in effect when the snackbar becomes visible.

#snackbar {
    /* ... (previous styles) */
    transition: opacity 0.5s ease;
}

#snackbar.show {
    opacity: 1;
}

In the JavaScript code, we’ll update the showSnackbar function to add and remove the show class for the animation:

function showSnackbar(message) {
    var snackbar = document.getElementById("snackbar");
    snackbar.innerHTML = message;
    snackbar.classList.add("show"); // Add the show class
    setTimeout(function () {
        snackbar.classList.remove("show"); // Remove the show class
    }, 3000);
}

6. Customization Options

You can customize the snackbar to match your website’s design by modifying the CSS styles. Here are some options you can consider:

  • Change the background color, text color, and font style.
  • Adjust the positioning of the snackbar on the screen.
  • Add icons or images to the snackbar for visual cues.

7. Best Practices for Implementation

When implementing snackbars on your website, keep these best practices in mind:

  • Use snackbars sparingly for important notifications.
  • Ensure the text is concise and easily readable.
  • Test the snackbar on various screen sizes and devices.
  • Provide keyboard accessibility for closing the snackbar.

8. Troubleshooting Common Issues

Issue: Snackbar doesn’t appear

  • Make sure you’ve included the necessary HTML and CSS.
  • Check if the JavaScript function is being called correctly.

Issue: Animation not working

  • Verify that you’ve added the CSS transition properties.
  • Check if the show class is being added and removed correctly in the JavaScript code.
