Introduction

In this article we will learn about Bootstrap Progress Bar component. In this article we will create Progress Bars with different styles using Bootstrap classes.

Bootstrap Progress Bar
 
Progress bars can be used to show the progress of a task or action to the users.

Now we will create different types of progress bars and see how it is useful for webpages.
 
Basic Progress Bar
 
We can create a default progress bar,by adding .progress class to a <div> element.
 
Example 1 : Creating Default Progress Bar
 
In this example to create a basic progress bar we will add a <div> with class .progress inside the container,now inside this <div>
we will add one more <div> with class .progress-bar, we will also add width in style attribute that indicate progress of task or action.
 
We will add .sr-only class for Progress Bar
  • .sr-only : It is used to hides an element to all devices except screen readers
We will add following properties for Progress Bar,
  • aria-valuenow : It is used to defines the current value for a range for Progress Bar
  • aria-valuemin :It is used to defines the minimum allowed value for a range
  • aria-valuemax :It is used to defines the maximum allowed value for a range
Lets create an example for Default Progress Bar by writing following code. 
  1. <!DOCTYPE html>  
  2.   
  3. <html lang="en">  
  4. <head>  
  5.     <meta charset="utf-8">  
  6.     <title>Bootstrap Part9</title>  
  7.     <meta name="viewport" content="width=device-width,initial-scale=1">  
  8.     <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">  
  9. </head>  
  10. <body>  
  11.     <div class="container">  
  12.         <h3>Basic Bootstrap Progress Bar (30% Complete)</h3>  
  13.         <!-- A <div> element with class .progress -->  
  14.         <div class="progress">  
  15.             <!-- A <div> element with class .progress-bar -->  
  16.             <div class="progress-bar" role="progressbar" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100" style="width:30%">  
  17.                 <span class="sr-only">30% Complete Process</span>  
  18.             </div>  
  19.         </div>  
  20.     </div>  
  21.     <script src="js/jquery-2.1.4.min.js"></script>  
  22.     <script src="js/bootstrap.min.js"></script>  
  23. </body>  
  24. </html>   
Output:
 
  
 
Progress Bar With Label
 
To show a visible progress status as a persentage we just remove the <span></span> with .sr-only class from the progress bar.
 
Example 2 : Progress Bar With Label
 
In this example we will create Progress Bar same like Example1 in this we want to show visible progress status so we will remove the <span> with .sr-only class from the progress bar.we will create Progress Bar With Label by writing following code. 
  1. <!DOCTYPE html>  
  2.   
  3. <html lang="en">  
  4. <head>  
  5.     <meta charset="utf-8">  
  6.     <title>Bootstrap Part9</title>  
  7.     <meta name="viewport" content="width=device-width,initial-scale=1">  
  8.     <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">  
  9. </head>  
  10. <body>  
  11.     <div class="container">  
  12.         <h3>Progress Bar With Label</h3>  
  13.         <!-- A <div> element with class .progress -->  
  14.         <div class="progress">  
  15.             <!-- A <div> element with class .progress-bar -->  
  16.             <div class="progress-bar" role="progressbar" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100" style="width:30%">  
  17.                 30%  
  18.             </div>  
  19.         </div>  
  20.     </div>  
  21.     <script src="js/jquery-2.1.4.min.js"></script>  
  22.     <script src="js/bootstrap.min.js"></script>  
  23. </body>  
  24. </html>

Colored Progress Bars with Contextual classes
 
Bootstrap provide Contextual classes for Progress Bar that is used to provide meaning through colors.
 
The contextual classes used with progress bars 
  • .progress-bar-info
  • .progress-bar-success

Example 3 : Creating Progress Bars with Contextual classes
 
In this example to create Colored Progress Bars we will add <div> with class .progress inside the container, now inside this <div> we will add one more <div> with class .progress-bar and we will add Contextual classes here like .progress-bar-info,.progress-bar-success,.progress-bar-danger,.progress-bar-warning.we will also add width in style attribute that indicate progress of task or action.we will also add aria attributes for progress bar,by writing following code.
