Simple Popup or Model Box Using HTML CSS and JavaScript


Dec 25, 2018

Popup boxes are the most useful way of showing a warning or any other important information to the website. In this article I’m going to walk you through the creation of a very simple popup box with shadow overlay and close button. We’re going to implement this using HTML, CSS and jQuery.

HTML Code:

add a link that triggers the box and a div that behaves like the box shadow. This wraps the actual box with the close button. The helper span is used to center the box vertically.


<h2>Animated Modal with Header and Footer</h2>


<button id="modelbtn">Click Here</button>

Popup or model code


<div id="myPopup" class="modalLayout">
  <div class="modalLayout-content">
    <div class="modalLayout-header">
      <span class="close">&times;</span>
      <h2>Modal Header</h2>
    </div>
    <div class="modalLayout-body">
      <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the</p>
      <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the</p>
    </div>
    <div class="modalLayout-footer">
      <h3>Modal Footer</h3>
    </div>
  </div>

</div>

CSS Code:


.modalLayout {
    display: none; 
    position: fixed;
    z-index: 1;
    left: 0;
    top: 0;
    width: 100%;
    background-color: rgb(0,0,0);
    background-color: rgba(0,0,0,0.4);
    padding-top: 100px;
    height: 100%;
}


.modalLayout-content {
	position: relative;
    background-color: #fff;
    margin: auto;
    width: 50%;
    border-radius: 12px;
    -webkit-animation-name: modelAnimation;
    -webkit-animation-duration: 0.5s;
    animation-name: modelAnimation;
    animation-duration: 0.5s
}

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

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

.close {
    color: #111;
    float: right;
    font-size: 32px;
    font-weight: bold;
    cursor: pointer;
}

.close:focus {
    color: #111;
    outline: none;
    cursor: pointer;
}

.modalLayout-header {
    padding: 2px 16px;
    color: #111;
    border-bottom: 1px solid silver;
}

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

.modalLayout-footer {
    padding: 2px 16px;
    color: #111;
    border-top: 1px solid silver;
}

JS Code:


var myPopup = document.getElementById('myPopup');
var modelbtn = document.getElementById("modelbtn");
var span = document.getElementsByClassName("close")[0];

 modelbtn.onclick  = function(){
    myPopup.style.display = "block";
}

 span.onclick  = function(){
    myPopup.style.display = "none";
}
window.onclick = function(e) {
    if (e.target == myPopup) {
        myPopup.style.display = "none";
    }
}
