Method 1: Using alert (simple popup)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Button Popup</title>
</head>
<body>
<button onclick="showPopup()">Click Me</button>
<script>
function showPopup() {
alert("Hello! This is your popup message.");
}
</script>
</body>
</html>
Method 2: Using a Modal Popup (styled popup)
This method uses CSS to style the popup as a modal and JavaScript to toggle its visibility.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Button Modal Popup</title>
<style>
/* Modal styles */
.modal {
display: none; /* Hidden by default */
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.5);
}
.modal-content {
background-color: #fff;
margin: 15% auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
max-width: 300px;
text-align: center;
border-radius: 8px;
}
.close {
color: #aaa;
float: right;
font-size: 24px;
cursor: pointer;
}
</style>
</head>
<body>
<button onclick="showModal()">Click Me</button>
<div id="myModal" class="modal">
<div class="modal-content">
<span class="close" onclick="closeModal()">×</span>
<p>Hello! This is your popup message.</p>
</div>
</div>
<script>
function showModal() {
document.getElementById("myModal").style.display = "block";
}
function closeModal() {
document.getElementById("myModal").style.display = "none";
}
// Close modal when clicking outside
window.onclick = function(event) {
let modal = document.getElementById("myModal");
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>
</body>
</html>
The first method provides a quick solution, while the second one gives you more control over the popup's style and appearance. Let me know if you need further customization!
