Toast message

Part of the JavaScript in Action section of Coddy's HTML journey — lesson 8 of 27.

A toast message is a small notification that briefly appears on the screen to give feedback to the user. It usually fades out after a few seconds.

Create a basic HTML structure:

<div class="container">
    <button id="showToast">Show Toast</button>
    <div id="toast" class="hidden">This is a toast message!</div>
</div>

Add some CSS to style the toast. We use two classes: .hidden to keep it invisible, and .show to make it appear.

.toast {
    position: fixed;
    bottom: 20px;
    left: 50%;
    background-color: #333;
    color: white;
    padding: 15px 25px;
}
.show {
    opacity: 1;
}
.hidden {
    display: none;
}

Now add JavaScript to show and hide the toast:

const showToastBtn = document.getElementById('showToast');
const toast = document.getElementById('toast');

showToastBtn.addEventListener('click', function() {
    toast.classList.remove('hidden');
    toast.classList.add('show');

    setTimeout(function() {
        toast.classList.remove('show');
        toast.classList.add('hidden');
    }, 3000);
});

This code makes the toast visible when the button is clicked, and automatically hides it after 3 seconds.

Challenge

Easy

Your goal is to make the toast look nice and ready for appearing/disappearing.

Place the toast message in the center at the bottom of the page using position: fixed with bottom and left.
Give it a background color and change the text color to make it readable.
Add some padding so the message isn’t cramped.
Make the corners look smooth.
Set its opacity to 0 so that it is hidden by default (before the JavaScript shows it).

Try it yourself

<!DOCTYPE html>
<html>
<head>
  <title>Toast Notification Example</title>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <header>
    <h1>My Profile Settings</h1>
  </header>

  <main>
    <p>Update your profile and save changes. A toast message will confirm your action.</p>
    <button id="showToast">Save Changes</button>
  </main>

  <!-- Toast -->
  <div id="toast" class="toast hidden">✅Your changes have been saved!</div>

  <script src="script.js"></script>
</body>
</html>
