There's a newer version of Bootstrap 4!

# Progress

Documentation and examples for using Bootstrap custom progress bars featuring support for stacked bars, animated backgrounds, and text labels.

## How it works

Progress components are built with two HTML elements, some CSS to set the width, and a few attributes. We don’t use the HTML5 `<progress>` element, ensuring you can stack progress bars, animate them, and place text labels over them.

- We use the `.progress` as a wrapper to indicate the max value of the progress bar.
- We use the inner `.progress-bar` to indicate the progress so far.
- The `.progress-bar` requires an inline style, utility class, or custom CSS to set their width.
- The `.progress-bar` also requires some `role` and `aria` attributes to make it accessible.

Put that all together, and you have the following examples.

    <div class="progress">
      <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
    </div>

Bootstrap provides a handful of utilities for setting width. Depending on your needs, these may help with quickly configuring progress.

    <div class="progress">
      <div class="progress-bar w-75" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
    </div>

## Labels

Add labels to your progress bars by placing text within the `.progress-bar`.

25%

    <div class="progress">
      <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">25%</div>
    </div>

## Height

We only set a `height` value on the `.progress`, so if you change that value the inner `.progress-bar` will automatically resize accordingly.

    <div class="progress" style="height: 1px;">
      <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress" style="height: 20px;">
      <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
    </div>

## Backgrounds

Use background utility classes to change the appearance of individual progress bars.

    <div class="progress">
      <div class="progress-bar bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
    </div>

## Multiple bars

Include multiple progress bars in a progress component if you need.

    <div class="progress">
      <div class="progress-bar" role="progressbar" style="width: 15%" aria-valuenow="15" aria-valuemin="0" aria-valuemax="100"></div>
      <div class="progress-bar bg-success" role="progressbar" style="width: 30%" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100"></div>
      <div class="progress-bar bg-info" role="progressbar" style="width: 20%" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100"></div>
    </div>

## Striped

Add `.progress-bar-striped` to any `.progress-bar` to apply a stripe via CSS gradient over the progress bar’s background color.

    <div class="progress">
      <div class="progress-bar progress-bar-striped" role="progressbar" style="width: 10%" aria-valuenow="10" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar progress-bar-striped bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar progress-bar-striped bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar progress-bar-striped bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    <div class="progress">
      <div class="progress-bar progress-bar-striped bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
    </div>

## Animated stripes

The striped gradient can also be animated. Add `.progress-bar-animated` to `.progress-bar` to animate the stripes right to left via CSS3 animations.

    <div class="progress">
      <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
    </div>
