In this tutorial we're going to create a simple progress bar with smooth loading effects with jQuery, HTML5 and CSS3. A little bit codes required. With this plugin, you can set your web page to redirect to another page while loading complete.

How to use it:

1. Include jQuery library on your web page

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> 

2. Create a container for your progress bar

<div class="progress"> <span class="blue" style="width:0%;"><span>0%</span></span> </div>

3. The CSS

.progress {
height: 20px;
background: #ebebeb;
border-left: 1px solid transparent;
border-right: 1px solid transparent;
border-radius: 10px;
}
.progress > span {
position: relative;
float: left;
margin: 0 -1px;
min-width: 30px;
height: 18px;
line-height: 16px;
text-align: right;
background: #cccccc;
border: 1px solid;
border-color: #bfbfbf #b3b3b3 #9e9e9e;
border-radius: 10px;
background-image: -webkit-linear-gradient(top, #f0f0f0, #dbdbdb 70%, #cccccc);
background-image: -moz-linear-gradient(top, #f0f0f0, #dbdbdb 70%, #cccccc);
background-image: -o-linear-gradient(top, #f0f0f0, #dbdbdb 70%, #cccccc);
background-image: linear-gradient(to bottom, #f0f0f0, #dbdbdb 70%, #cccccc);
-webkit-box-shadow: inset 0 1px rgba(255, 255, 255, 0.3), 0 1px 2px rgba(0, 0, 0, 0.2);
box-shadow: inset 0 1px rgba(255, 255, 255, 0.3), 0 1px 2px rgba(0, 0, 0, 0.2);
}
.progress > span > span {
padding: 0 8px;
font-size: 11px;
font-weight: bold;
color: #404040;
color: rgba(0, 0, 0, 0.7);
text-shadow: 0 1px rgba(255, 255, 255, 0.4);
}
.progress > span:before {
content: '';
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
z-index: 1;
height: 18px;
background: url("../images/progress.png") 0 0 repeat-x;

}
.progress .green {

background-image: linear-gradient(to bottom, #b7dc8e, #99ce5f 70%, #85c440);
}
.progress .red {

background-image: linear-gradient(to bottom, #aed5ed, #7bbbe2 70%, #5aaadb);
}

4. The javascript

<script type='text/javascript'>
function loading(percent){
$('.progress span').animate({width:percent},1000,function(){
$(this).children().html(percent);
if(percent=='100%'){
 $(this).children().html('Loading Complete, Redirect to Home Page...&nbsp;&nbsp;&nbsp;&nbsp;');
setTimeout(function(){
$('.container').fadeOut();
location.href="https://www.jqueryscript.net";
},1000);
}
})
}
</script>

5. Set the pre-loading content

<script type="text/javascript">loading('5%');</script>
