Auto popup with close button using html, CSS

Question

Hi I have code which generates a popup on button click. But can any one please modify my code so that I can insert that code in my page and get an auto popup on my page load.

I wish to insert this code in success page of project which appears after completion of a form.

.box {
  width: 20%;
  margin: 0 auto;
  background: rgba(255,255,255,0.2);
  padding: 35px;
  border: 2px solid #fff;
  border-radius: 20px/50px;
  background-clip: padding-box;
  text-align: center;
}

.button {
  font-size: 1em;
  padding: 10px;
  color: #fff;
  border: 2px solid orange;
  border-radius: 20px/50px;
  text-decoration: none;
  cursor: pointer;
  transition: all 0.3s ease-out;
}
.button:hover {
  background: orange;
}

.overlay {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.7);
  transition: opacity 500ms;
  visibility: hidden;
  opacity: 0;
}
.overlay:target {
  visibility: visible;
  opacity: 1;
}

.popup {
  margin: 70px auto;
  padding: 20px;
  background: #fff;
  border-radius: 5px;
  width: 30%;
  position: relative;
  transition: all 5s ease-in-out;
}

.popup h2 {
  margin-top: 0;
  color: #333;
  font-family: Tahoma, Arial, sans-serif;
}
.popup .close {
  position: absolute;
  top: 20px;
  right: 30px;
  transition: all 200ms;
  font-size: 30px;
  font-weight: bold;
  text-decoration: none;
  color: #333;
}
.popup .close:hover {
  color: orange;
}
.popup .content {
  max-height: 30%;
  overflow: auto;
}

<div class="box">
	<a class="button" href="#popup1">Let me Pop up</a>
</div>

<div id="popup1" class="overlay">
	<div class="popup">
		<h2>Here i am</h2>
		<a class="close" href="#">×</a>
		<div class="content">
			Thank to pop me out of that button, but now i'm done so you can close this window.
		</div>
	</div>
</div>

You're looking for the target CSS psuedo-class.

Without JQuery you can use fragment identifiers. Any element whose ID matches the fragment identifier will automatically have the :target CSS psuedo-class applied to it.

You can then use CSS rules to hide the popup by default and show it when it is :targeted, (or the other way around), and add buttons to open and close the popup via navigating to the relevant fragment.

.box {
    width: 20%;
    margin: 0 auto;
    background: rgba(255, 255, 255, 0.2);
    padding: 35px;
    border: 2px solid #fff;
    border-radius: 20px/50px;
    background-clip: padding-box;
    text-align: center;
}

.button {
    font-size: 1em;
    padding: 10px;
    color: #fff;
    border: 2px solid orange;
    border-radius: 20px/50px;
    text-decoration: none;
    cursor: pointer;
    transition: all 0.3s ease-out;
}

.button:hover {
    background: orange;
}

.popup {
    margin: 70px auto;
    padding: 20px;
    background: #fff;
    border-radius: 5px;
    width: 30%;
    position: relative;
    transition: all 5s ease-in-out;
}

.popup h2 {
    margin-top: 0;
    color: #333;
    font-family: Tahoma, Arial, sans-serif;
}

.popup .close {
    position: absolute;
    top: 20px;
    right: 30px;
    transition: all 200ms;
    font-size: 30px;
    font-weight: bold;
    text-decoration: none;
    color: #333;
}

.popup .close:hover {
    color: orange;
}

.popup .content {
    max-height: 30%;
    overflow: auto;
}

.overlay {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    background: rgba(0, 0, 0, 0.7);
}

/* These are the rules you are looking for. */
.overlay {
    transition: opacity 500ms;
    opacity: 1;
    pointer-events: all;
}

.overlay:target {
    opacity: 0;
    pointer-events: none;
}

<div class="box">
    <!-- This shows the popup. -->
    <a class="button" href="#popup">Let me Pop up</a>
</div> 

<div id="popup1" class="overlay">
    <div class="popup" >
        <h2>Here i am</h2>
        <!-- This hides it. -->
        <a class="close" href="#popup1">×</a>
        <div class="content">
            Thank to pop me out of that button, but now I'm done so you can close this window.
        </div>
    </div>
</div>

You can use JQuery for that. Check Below code working so far:

$(document).ready(function() {
    $(function(){
      
      $('#popup1').css("visibility", "visible"); 
       $('#popup1').css("opacity", 1); 
      
       });
  
  $( ".close" ).click(function() {
    
       $('#popup1').css("visibility", "hidden"); 
       $('#popup1').css("opacity", 0);
    });
});

.box {
  width: 20%;
  margin: 0 auto;
  background: rgba(255,255,255,0.2);
  padding: 35px;
  border: 2px solid #fff;
  border-radius: 20px/50px;
  background-clip: padding-box;
  text-align: center;
}

.button {
  font-size: 1em;
  padding: 10px;
  color: #fff;
  border: 2px solid orange;
  border-radius: 20px/50px;
  text-decoration: none;
  cursor: pointer;
  transition: all 0.3s ease-out;
}
.button:hover {
  background: orange;
}

.overlay {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.7);
  transition: opacity 500ms;
  visibility: hidden;
  opacity: 0;
}
.overlay:target {
  visibility: visible;
  opacity: 1;
}

.popup {
  margin: 70px auto;
  padding: 20px;
  background: #fff;
  border-radius: 5px;
  width: 30%;
  position: relative;
  transition: all 5s ease-in-out;
}

.popup h2 {
  margin-top: 0;
  color: #333;
  font-family: Tahoma, Arial, sans-serif;
}
.popup .close {
  position: absolute;
  top: 20px;
  right: 30px;
  transition: all 200ms;
  font-size: 30px;
  font-weight: bold;
  text-decoration: none;
  color: #333;
}
.popup .close:hover {
  color: orange;
}
.popup .content {
  max-height: 30%;
  overflow: auto;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="box">
	<a class="button" href="#popup1">Let me Pop up</a>
</div>

<div id="popup1" class="overlay">
	<div class="popup">
		<h2>Here i am</h2>
		<a class="close" href="#">×</a>
		<div class="content">
			Thank to pop me out of that button, but now i'm done so you can close this window.
		</div>
	</div>
</div>

There isn't a way to do an auto popup/lightbox on page load with CSS.

To make this work you will need to add a little jquery to your code above. This below will give you all the features you could want from the pop up

$(document).ready(function() {  

var id = '#dialog';

//Get the screen height and width
var maskHeight = $(document).height();
var maskWidth = $(window).width();

//Set heigth and width to mask to fill up the whole screen
$('#mask').css({'width':maskWidth,'height':maskHeight});

//transition effect
$('#mask').fadeIn(500); 
$('#mask').fadeTo("slow",0.9);  

//Get the window height and width
var winH = $(window).height();
var winW = $(window).width();

//Set the popup window to center
$(id).css('top',  winH/2-$(id).height()/2);
$(id).css('left', winW/2-$(id).width()/2);

//transition effect
$(id).fadeIn(2000);     

//if close button is clicked
$('.window .close').click(function (e) {
//Cancel the link behavior
e.preventDefault();

$('#mask').hide();
$('.window').hide();
});

//if mask is clicked
$('#mask').click(function () {
$(this).hide();
$('.window').hide();
});

});

And lastly add the jQuery library in the page

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.js"></script>
