How to Create a Modal Box

How To Create a Modal Box

A modal is a dialog box/popup window that is displayed on top of the current page:


Step 1) Add HTML:

CODE:

<!– 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”>&times;</span>
<p>Some text in the Modal..</p>
</div></div>


Step 2) Add CSS:

CODE:

/* 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;
}


Step 3) Add 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.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”;
}
}


Add Header and Footer

Add a class for modal-header, modal-body and modal-footer:

CODE:

<!– Modal content –>
<div class=”modal-content”>
<div class=”modal-header”>
<span class=”close”>&times;</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>

Style the modal header, body and footer, and add animation (slide in the modal):

CODE:

/* 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);
-webkit-animation-name: animatetop;
-webkit-animation-duration: 0.4s;
animation-name: animatetop;
animation-duration: 0.4s
}

/* Add Animation */
@-webkit-keyframes animatetop {
from {top: -300px; opacity: 0}
to {top: 0; opacity: 1}
}

@keyframes animatetop {
from {top: -300px; opacity: 0}
to {top: 0; opacity: 1}
}

padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */

Bottom Modal (“Bottom sheets”)

An example on how to create a full-width modal that slides in from the bottom:

CODE:

<!DOCTYPE html>
<html>
<head>
<style>
/* 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 */
-webkit-animation-name: fadeIn; /* Fade in the background */
-webkit-animation-duration: 0.4s;
animation-name: fadeIn;
animation-duration: 0.4s
}

/* Modal Content */
.modal-content {
position: fixed;
bottom: 0;
background-color: #fefefe;
width: 100%;
-webkit-animation-name: slideIn;
-webkit-animation-duration: 0.4s;
animation-name: slideIn;
animation-duration: 0.4s
}

/* The Close Button */
.close {
color: white;
float: right;
font-size: 28px;
font-weight: bold;
}

.close:hover,
.close:focus {
color: #000;
text-decoration: none;
cursor: pointer;
}

.modal-header {
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}

.modal-body {padding: 2px 16px;}

.modal-footer {
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}

/* Add Animation */
@-webkit-keyframes slideIn {
from {bottom: -300px; opacity: 0}
to {bottom: 0; opacity: 1}
}

@keyframes slideIn {
from {bottom: -300px; opacity: 0}
to {bottom: 0; opacity: 1}
}

@-webkit-keyframes fadeIn {
from {opacity: 0}
to {opacity: 1}
}

@keyframes fadeIn {
from {opacity: 0}
to {opacity: 1}
}
</style>
</head>
<body>
