Hi friends In this article I’m explaining about CSS3 features stylish progress bars using css3.

Description:

You've seen progress bars everywhere, they are those bars that display the current completion state for a process, such as a download or file transfer. Whether you're building a desktop or a web application, at a certain point, you may need to use this UI element.

Having said that, in this article you'll learn how to create stylish and animated progress bars using CSS3.

HTML

<div class="progress-bar blue
stripes">
    <span style="width: 40%"></span>
</div>

CSS

.progress-bar {
    background-color: #1a1a1a;
    height: 25px;
    padding: 5px;
    width: 350px;
    margin: 50px 0;         
    border-radius: 5px;
    box-shadow: 0 1px 5px #000 inset, 0 1px 0 #444;           
}
 
.progress-bar span {
    display: inline-block;
    height: 100%;
    border-radius: 3px;
    box-shadow: 0 1px 0 rgba(255, 255, 255, .5) inset;
    transition: width .4s ease-in-out;    
    background-color:#a5a5a5;
}

Output

Let's add some color, gradients, stripes:

You may have seen this CSS3 technique before, I just adapted it a little for this example:

 

.progress-bar {
    background-color: #1a1a1a;
    height: 25px;
    padding: 5px;
    width: 350px;
    margin: 50px 0;         
    border-radius: 5px;
    box-shadow: 0 1px 5px #000 inset, 0 1px 0 #444;           
}
 
.progress-bar span {
    display: inline-block;
    height: 100%;
    border-radius: 3px;
    box-shadow: 0 1px 0 rgba(255, 255, 255, .5) inset;
    transition: width .4s ease-in-out;    
    background-color:#a5a5a5;
}
 
.blue span {
    background-color: #34c2e3;   
}
 
.orange span {
      background-color: #fecf23;
      background-image: linear-gradient(top, #fecf23, #fd9215);  
}   
 
.green span {
      background-color: #a5df41;
      background-image: linear-gradient(top, #a5df41, #4ca916);  
}
 
.stripes span {
    background-size: 30px 30px;
    background-image: linear-gradient(135deg, rgba(255, 255, 255, .15) 25%, transparent 25%,
                        transparent 50%, rgba(255, 255, 255, .15) 50%, rgba(255, 255, 255, .15) 75%,
                        transparent 75%, transparent);            
    
    animation: animate-stripes 3s linear infinite;             
}
 
@keyframes animate-stripes {
    0% {background-position: 0 0;} 100% {background-position: 60px 0;}
}

 

Output

Shine

Not sure if this is the best name I could find for this CSS3 animation, but here we go:

HTML

<div class="progress-bar blue
stripes">
    <span style="width: 40%"></span>
</div>
<div class="progress-bar orange
shine">
    <span style="width: 100%"></span>
</div>
<div class="progress-bar green
stripes">
    <span style="width: 50%"></span>
</div>

 

CSS

.progress-bar {
    background-color: #1a1a1a;
    height: 25px;
    padding: 5px;
    width: 350px;
    margin: 50px 0;         
    border-radius: 5px;
    box-shadow: 0 1px 5px #000 inset, 0 1px 0 #444;           
}
 
.progress-bar span {
    display: inline-block;
    height: 100%;
    border-radius: 3px;
    box-shadow: 0 1px 0 rgba(255, 255, 255, .5) inset;
    transition: width .4s ease-in-out;    
    background-color:#a5a5a5;
}
 
.blue span {
    background-color: #34c2e3;   
}
 
.orange span {
      background-color: #fecf23;
      background-image: linear-gradient(top, #fecf23, #fd9215);  
}   
 
.green span {
      background-color: #a5df41;
      background-image: linear-gradient(top, #a5df41, #4ca916);  
}
 
.stripes span {
    background-size: 30px 30px;
    background-image: linear-gradient(135deg, rgba(255, 255, 255, .15) 25%, transparent 25%,
                        transparent 50%, rgba(255, 255, 255, .15) 50%, rgba(255, 255, 255, .15) 75%,
                        transparent 75%, transparent);            
    
    animation: animate-stripes 3s linear infinite;             
}
 
@keyframes animate-stripes {
    0% {background-position: 0 0;} 100% {background-position: 60px 0;}
}
 
.shine span {
    position: relative;
}
 
.shine span::after {
    content: '';
    opacity: 0;
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background: #fff;
    border-radius: 3px;
    animation: animate-shine 2s ease-out infinite;             
}
 
@keyframes animate-shine {
    0% {opacity: 0; width: 0;}
    50% {opacity: .5;}
    100% {opacity: 0; width: 95%;}
}

 

Output

Glow

CSS3 keyframes animation based on box-shadow property:

.glow span {
    box-shadow: 0 5px 5px rgba(255, 255, 255, .7) inset, 0 -5px 5px rgba(255, 255, 255, .7) inset;    
    animation: animate-glow 1s ease-out infinite;          
}
 
@keyframes animate-glow {
 0% { box-shadow: 0 5px 5px rgba(255, 255, 255, .7) inset, 0 -5px 5px rgba(255, 255, 255, .7) inset;} 
 50% { box-shadow: 0 5px 5px rgba(255, 255, 255, .3) inset, 0 -5px 5px rgba(255, 255, 255, .3) inset;} 
 100% { box-shadow: 0 5px 5px rgba(255, 255, 255, .7) inset, 0 -5px 5px rgba(255, 255, 255, .7) inset;}
 }
