Bootstrap Progress Bars


Hello folks! welcome back to a new section of our tutorial on Bootstrap. In this tutorial guide, we are going to be discussing about Bootstrap progress bars.

The purpose of progress bar is to show that assets are loading, in progress or that there is an action happening regarding elements on the page.

Progress bars uses CSS3 transitions and animations to obtain some of their effects. These features aren't supported in Internet Explorer(IE)9 and below or older versions of Firefox. Opera 12 does not have support for animations.

Default Progress Bar

To create a basic progress bar -

  • Add a <div> with a .progress class.
  • Next, inside the above <div>, add an empty <div> with a .progress-bar class.
  • Finally add a style attribute with the width expressed as a percentage. For example, style ="60%"; shows that the progress bar is at 60%.

Example

Following example demonstrates this -

<div class = "progress">
   <div class = "progress-bar" role = "progressbar" aria-valuenow = "60" 
      aria-valuemin = "0" aria-valuemax = "100" style = "width: 40%;">
      
      <span class = "sr-only">40% Complete</span>
   </div>
</div>

Output

When the above example is executed, it will produce the following result -

Default Progress Bar


Alternate Progress Bar

To create a progress bar that has a different styling -

  • Add a <div> with a class of .progress
  • Inside the above <div>, add an empty <div> with a .progress-bar class and class .progress-bar-* where * could be success, info, warning, danger.
  • Finally add a style attribute with the width expressed as a percentage. For example style ="60%"; shows that the progress bar was at 60%.

Example

Following below is a simple example -

<div class = "progress">
   <div class = "progress-bar progress-bar-success" role = "progressbar" 
      aria-valuenow = "60" aria-valuemin = "0" aria-valuemax = "100" style = "width: 90%;">
      
      <span class = "sr-only">90% Complete (Sucess)</span>
   </div>
</div>
