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:
Example
<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).
Note: To help improve accessibility for
people using screen readers, you should include the aria-* attributes.
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:
Example
<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:
Example
<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>

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>

Free Space
</div>
<div class="progress-bar progress-bar-warning" role="progressbar" style="width:10%">
