Hoe om 'n modale boks te skep
'n Modaal is 'n dialoogkassie/opspringvenster wat bo-op die huidige bladsy vertoon word:
Stap 1) Voeg HTML by:
Voorbeeld
<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>
<!--
The Modal -->
<div id="myModal" class="modal">
<!-- Modal
content -->
<div class="modal-content">
<span class="close">×</span>
<p>Some text in the
Modal..</p>
</div>
</div>
Stap 2) Voeg CSS by:
Voorbeeld
/* 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;
}
Stap 3) Voeg JavaScript by:
Voorbeeld
// 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";
}
}
Voeg kop- en voetskrif by
Voeg 'n klas by vir modale kopskrif, modale liggaam en modale voetskrif:
Voorbeeld
<!-- Modal content -->
<div class="modal-content">
<div
class="modal-header">
<span class="close">×</span>
<h2>Modal Header</h2>
</div>
<div class="modal-body">
<p>Some text in the Modal Body</p>
<p>Some other
text...</p>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
</div>
</div>
Stileer die modale kop, liggaam en voetskrif, en voeg animasie by (skuif in die modaal):
Voorbeeld
/* Modal Header */
.modal-header {
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}
/* Modal Body */
.modal-body {padding: 2px 16px;}
/* Modal Footer */
.modal-footer {
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}
/* Modal Content */
.modal-content {
position: relative;
background-color: #fefefe;
margin: auto;
padding: 0;
border: 1px solid #888;
width: 80%;
box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2),0 6px 20px 0 rgba(0,0,0,0.19);
animation-name: animatetop;
animation-duration: 0.4s
}
/* Add Animation */
@keyframes animatetop {
from {top: -300px; opacity: 0}
to {top: 0; opacity: 1}
}
