<div id="myModal" class="modal">
<!-- Pop-up content -->
<div class="modal-content">
<span class="close">×</span>
<p>Text in the pop-up...</p>
</div>
</div>
CSS Code:
/* The pop-up (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Fixed position */
z-index: 1; /* Place on top */
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgb(0,0,0);
background-color: rgba(0,0,0,0.4);
}
/* Pop-up content */
.modal-content {
background-color: #fefefe;
margin: 15% auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}
/* The close button */
.close {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: black;
text-decoration: none;
cursor: pointer;
}
JavaScript Code:
// Get the modal
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.querySelector('.close');
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
