</div>
</div>Étape 2) Ajouter CSS:
Exemple
/* The Modal (background) */
.modal {
display: none;
/* Hidden by default */
position: fixed; /* Stay in
place */
z-index: 1; /* Sit on top */
left: 0;
top: 0;
width: 100%; /*
Full width */
height: 100%; /* Full height */
overflow: auto; /*
Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4);
/* Black w/ opacity */
}
/* Modal Content/Box */
.modal-content {
background-color: #fefefe;
margin: 15% auto; /* 15%
from the top and centered */
padding: 20px;
border: 1px
solid #888;
width: 80%; /* Could be more or less,
depending on screen size */
}
/* 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;
}Étape 3) Ajouter JavaScript:
Exemple
// 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.getElementsByClassName("close")[0];
// When the user clicks
on 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";
}
