How to Create a Modal Popup with a Fade and Slide Effect

Modals are a great way to grab attention and present information without leaving the current page. In this tutorial, we’ll learn how to create a stylish modal popup that fades in and slides down from the top using HTML, CSS, and JavaScript.

Step 1: HTML Structure

Start by creating the basic structure of the modal:

<button id="openModal">Open Modal</button>
 
<div id="modal" class="modal">
    <div class="modal-content">
        <span id="closeModal" class="close">×</span>
        <h2>Modal Title</h2>
        <p>This is a modal popup with a fade and slide effect!</p>
    </div>
</div>
  • The 'button' element triggers the modal.
  • The 'div' with the'modal' class serves as the overlay.
  • The 'div' with the 'modal-content' class contains the modal’s content.

Step 2: CSS Styling

Use CSS for styling and animation:

body {
    font-family: Arial, sans-serif;
}
 
button {
    margin: 20px;
    padding: 10px 20px;
    font-size: 16px;
    cursor: pointer;
}
 
.modal {
    display: none;
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background: rgba(0, 0, 0, 0.5);
    justify-content: center;
    align-items: flex-start;
    animation: fadeIn 0.3s ease-out;
}
 
.modal-content {
    margin: 100px auto;
    background: #fff;
    padding: 20px;
    border-radius: 8px;
    box-shadow: 0 5px 15px rgba(0, 0, 0, 0.3);
    width: 80%;
    max-width: 500px;
    animation: slideDown 0.5s ease-out;
}
 
.close {
    position: absolute;
    top: 10px;
    right: 20px;
    font-size: 24px;
    cursor: pointer;
}
 
@keyframes fadeIn {
    from {
        background: rgba(0, 0, 0, 0);
    }
    to {
        background: rgba(0, 0, 0, 0.5);
    }
}
 
@keyframes slideDown {
    from {
        transform: translateY(-50px);
        opacity: 0;
    }
    to {
        transform: translateY(0);
        opacity: 1;
    }
}

Step 3: JavaScript for Interaction

Now, add JavaScript to handle the modal’s behavior:

document.getElementById('openModal').addEventListener('click', function () {
    const modal = document.getElementById('modal');
    modal.style.display = 'flex';
});
 
document.getElementById('closeModal').addEventListener('click', function () {
    const modal = document.getElementById('modal');
    modal.style.display = 'none';
});
 
window.addEventListener('click', function (e) {
    const modal = document.getElementById('modal');
    if (e.target === modal) {
        modal.style.display = 'none';
    }
});

This script ensures that:

  • Clicking the "Open Modal" button shows the modal.
  • Clicking the close button or outside the modal content hides it.
