Bootstrap Progress Bars



Basic Progress Bar:
A progress bar can be used to show a user how far along he/she is in a process.
Bootstrap provides several types of progress bars.
A default progress bar in Bootstrap looks like this:
To create a default progress bar, add a .progress class to a <div> element:
<div class="progress">
  
<div class="progress-bar" role="progressbar" aria-valuenow="70"
  aria-valuemin=
"0" aria-valuemax="100" style="width:70%">
    
<span class="sr-only">70% Complete</span>
  
</div>
</div>
Note: Progress bars are not supported in Internet Explorer 9 and earlier (because they use CSS3 transitions and animations to achieve some of their effects).

Progress Bar With Label:

A progress bar with a label looks like this:
Remove the .sr-only class from the progress bar to show a visible percentage:
<div class="progress">
  
<div class="progress-bar" role="progressbar" aria-valuenow="70"
  aria-valuemin=
"0" aria-valuemax="100" style="width:70%">
    70%
  
</div>
</div>

 

 

Colored Progress Bars:

Contextual classes are used to provide "meaning through colors".
The contextual classes that can be used with progress bars are:

  •  .progress-bar-success
  •  .progress-bar-info
  • .progress-bar-warning
  • .progress-bar-danger

The following example shows how to create progress bars with the different contextual classes:
<div class="progress">
  
<div class="progress-bar progress-bar-success" role="progressbar" aria-valuenow="40"
  aria-valuemin=
"0" aria-valuemax="100" style="width:40%">
    40% Complete (success)
  
</div>
</div>

<div class="progress">
  
<div class="progress-bar progress-bar-info" role="progressbar" aria-valuenow="50"
  aria-valuemin=
"0" aria-valuemax="100" style="width:50%">
    50% Complete (info)
  
</div>
</div>

<div class="progress">
  
<div class="progress-bar progress-bar-warning" role="progressbar" aria-valuenow="60"
  aria-valuemin=
"0" aria-valuemax="100" style="width:60%">
    60% Complete (warning)
  
</div>
</div>

<div class="progress">
  
<div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="70"
  aria-valuemin=
"0" aria-valuemax="100" style="width:70%">
    70% Complete (danger)
  
</div>
</div>


Striped Progress Bars:

Progress bars can also be striped:
Add class .progress-bar-striped to add stripes to the progress bars:
<div class="progress">
  
<div class="progress-bar progress-bar-success progress-bar-striped" role="progressbar"
  aria-valuenow=
"40" aria-valuemin="0" aria-valuemax="100" style="width:40%">
    40% Complete (success)
  
</div>
</div>

<div class="progress">
  
<div class="progress-bar progress-bar-info progress-bar-striped" role="progressbar"
  aria-valuenow=
"50" aria-valuemin="0" aria-valuemax="100" style="width:50%">
    50% Complete (info)
  
</div>
</div>

<div class="progress">
  
<div class="progress-bar progress-bar-warning progress-bar-striped" role="progressbar"
  aria-valuenow=
"60" aria-valuemin="0" aria-valuemax="100" style="width:60%">
    60% Complete (warning)
  
</div>
</div>

<div class="progress">
  
<div class="progress-bar progress-bar-danger progress-bar-striped" role="progressbar"
  aria-valuenow=
"70" aria-valuemin="0" aria-valuemax="100" style="width:70%">
    70% Complete (danger)
  
</div>
</div>

 

 

Animated Progress Bar:

Here is an "animated" progress bar:
Add class .active to animate the progress bar:
<div class="progress">
  
<div class="progress-bar progress-bar-striped active" role="progressbar"
  aria-valuenow=
"40" aria-valuemin="0" aria-valuemax="100" style="width:40%">
    40%
  
</div>
</div>

 

 

Stacked Progress Bars:

Progress bars can also be stacked:
Create a stacked progress bar by placing multiple bars into the same <div class="progress">:
<div class="progress">
  
<div class="progress-bar progress-bar-success" role="progressbar" style="width:40%">
    Free Space
  
</div>
  
<div class="progress-bar progress-bar-warning" role="progressbar" style="width:10%">
    Warning
  
</div>
  
<div class="progress-bar progress-bar-danger" role="progressbar" style="width:20%">
    Danger
  
</div>
</div>
