I’ve shared a way to add a pop-up or modal lightbox with CSS only on my earlier post, Easy Modal Lightbox Pop-Up. I’ve received many request how to make this modal pop up on page load instead of using a button. So, here’s how-to:

HTML

Copy the code below and paste into your HTML document.

<div id="modal-1" class="modal animate-opacity">
   <div class="modal-content">
      <div class="modal-inner">
         <span onclick="document.getElementById('modal-1').style.display='none'" class="modal-close">&times;</span>
         <h4>Modal Headline</h4>
         <p>Modal description goes here.</p>
      </div> 
   </div>
</div>

CSS

Copy the code below and paste into your CSS document.

.modal {
	z-index: 10;
	display: block;
	padding-top: 100px;
	position: fixed;
	left: 0;
	top: 0;
	width: 100%;
	height: 100%;
	overflow: auto;
	background-color: rgb(0,0,0);
	background-color: rgba(0,0,0,0.5)
}
.modal-content {
	margin: auto;
	background-color: #fff;
	position: relative;
	padding: 0;
	outline: 0;
	max-width: 600px
}
.modal-inner { padding: 20px 30px; }
.modal-close {
	-webkit-touch-callout: none;
	-webkit-user-select: none;
	-khtml-user-select: none;
	-moz-user-select: none;
	-ms-user-select: none;
	user-select: none;
	position: absolute;
	right: 0;
	top: 0;
	background: #ccc;
	padding: 6px 10px;
}
.animate-opacity { animation: opac 0.8s }@keyframes opac{from{opacity:0} to{opacity:1}}

.animate-opacity is optional as it’s the animated effect when modal opens.

You can tweak the animation time. It’s currently 0.8 seconds opac 0.8s , but change the timing as your need.

Woocommerce offers one of a greatest E-Commerce template themes for free called, “Storefront“. From the Nav to checkout process, all required functionality in order to run an E-Commerce are ready for you to download and activate. But, one little thing is bugging at the bottom of the page, “Built with Storefront & WooCommerce.” line, however, it’s possible to get it out with a few lines of CSS.

Remove and replace copyright information on Storefront theme

footer .site-infos { display:none; } 				
footer .footer-widgets { border: 0 !important;	}	
footer .footer-widgets::after {  content: "© ADD THIS FOR YOUR COPYRIGHT INFO" }

Let’s don’t bother spending hours to look for footer.php or widgets in WordPress to add your Copyright line on the footer of website. Here’s one easy method to add using CSS.

Add copyright text / info with CSS for WordPress/Bootstrap websites

footer > div:before {
    content: "© Copyright (YEAR). All rights reserved.";
    font-size: 14px;
    color: #777;
    text-align: center;
    display: block;
    margin: 20px auto;
}

Now you can add pop-ups or modal lightbox with CSS only (and really minor single line of JavaScript) on your html, wordpress or bootstrap website, so don’t be afraid.

HTML

Copy the code below and paste into your HTML document.

<button onclick="document.getElementById('modal-1').style.display='block'">Click Here</button>

<div id="modal-1" class="modal animate-opacity">
   <div class="modal-content">
      <div class="modal-inner">
         <span onclick="document.getElementById('modal-1').style.display='none'" class="modal-close">&times;</span>
         <h4>Modal Headline</h4>
         <p>Modal description goes here.</p>
      </div> 
   </div>
</div>

You can add multiple modals. Copy the entire codes and replace all modal-1 into modal-2 and modal-3 …

CSS

Copy the code below and paste into your CSS document.

.modal {
	z-index: 10;
	display: none;
	padding-top: 100px;
	position: fixed;
	left: 0;
	top: 0;
	width: 100%;
	height: 100%;
	overflow: auto;
	background-color: rgb(0,0,0);
	background-color: rgba(0,0,0,0.5)
}
.modal-content {
	margin: auto;
	background-color: #fff;
	position: relative;
	padding: 0;
	outline: 0;
	max-width: 600px
}
.modal-inner { padding: 20px 30px; }
.modal-close {
	-webkit-touch-callout: none;
	-webkit-user-select: none;
	-khtml-user-select: none;
	-moz-user-select: none;
	-ms-user-select: none;
	user-select: none;
	position: absolute;
	right: 0;
	top: 0;
	background: #ccc;
	padding: 6px 10px;
}
.animate-opacity { animation: opac 0.8s }@keyframes opac{from{opacity:0} to{opacity:1}}

These 4 classes would do the job, and the last class, .animate-opacity is the animated effect when modal opens (so it’s optional).

You can tweak the animation time slower or faster by changing the speed time. It’s currently 0.8 seconds, opac 0.8s, but change it as you need it. Have fun!
