## 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](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/progress), 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.
- The `.progress` wrapper also requires a `role="progressbar"` and `aria` attributes to make it accessible, including an accessible name (using `aria-label`, `aria-labelledby`, or similar).
- We use the inner `.progress-bar` purely for the visual bar and label.
- The `.progress-bar` requires an inline style, utility class, or custom CSS to set its width.
- We provide a special `.progress-stacked` class to create multiple/stacked progress bars.

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

<Example code={`<div class="progress" role="progressbar" aria-label="Basic example" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar" style="width: 0%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Basic example" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar" style="width: 25%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Basic example" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar" style="width: 50%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Basic example" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar" style="width: 75%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Basic example" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar" style="width: 100%"></div>
  </div>`} />

## Bar sizing

### Width

Bootstrap provides a handful of [utilities for setting width]([[docsref:/utilities/sizing]]). Depending on your needs, these may help with quickly configuring the width of the `.progress-bar`.

<Example code={`<div class="progress" role="progressbar" aria-label="Basic example" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar w-75"></div>
  </div>`} />

### Height

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

<Example code={`<div class="progress" role="progressbar" aria-label="Example 1px high" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100" style="height: 1px">
    <div class="progress-bar" style="width: 25%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Example 20px high" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100" style="height: 20px">
    <div class="progress-bar" style="width: 25%"></div>
  </div>`} />

## Labels

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

<Example code={`<div class="progress" role="progressbar" aria-label="Example with label" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar" style="width: 25%">25%</div>
  </div>`} />

### Long labels

Note that by default, the content inside the `.progress-bar` is controlled with `overflow: hidden`, so it doesn’t bleed out of the bar. If your progress bar is shorter than its label, the content will be capped and may become unreadable. To change this behavior, you can use `.overflow-visible` from the [overflow utilities]([[docsref:/utilities/overflow]]).

<Callout type="warning">
Labels longer than the progress bar within may not be fully accessible using this method because it relies on the text color having the correct contrast ratio with both the `.progress` and `.progress-bar` background colors. Use caution when implementing this example.

If the text can overlap the progress bar, we often recommend displaying the label outside of the progress bar for better accessibility.
</Callout>

## Backgrounds

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

<Example code={`<div class="progress" role="progressbar" aria-label="Success example" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar bg-success" style="width: 25%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Info example" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar bg-info" style="width: 50%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Warning example" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar bg-warning" style="width: 75%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Danger example" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar bg-danger" style="width: 100%"></div>
  </div>`} />

<Callout name="warning-color-assistive-technologies" />

If you’re adding labels to progress bars with a custom background color, make sure to also set an appropriate [text color]([[docsref:/utilities/colors#colors]]), so the labels remain readable and have sufficient contrast. We recommend using the [color and background]([[docsref:/helpers/color-background]]) helper classes.

<Example code={`<div class="progress" role="progressbar" aria-label="Success example" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar text-bg-success" style="width: 25%">25%</div>
  </div>
  <div class="progress" role="progressbar" aria-label="Info example" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar text-bg-info" style="width: 50%">50%</div>
  </div>
  <div class="progress" role="progressbar" aria-label="Warning example" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar text-bg-warning" style="width: 75%">75%</div>
  </div>
  <div class="progress" role="progressbar" aria-label="Danger example" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar text-bg-danger" style="width: 100%">100%</div>
  </div>`} />

## Multiple bars

You can include multiple progress components inside a container with `.progress-stacked` to create a single stacked progress bar. Note that in this case, the styling to set the visual width of the progress bar *must* be applied to the `.progress` elements, rather than the `.progress-bar`s.

<Example code={`<div class="progress-stacked">
    <div class="progress" role="progressbar" aria-label="Segment one" aria-valuenow="15" aria-valuemin="0" aria-valuemax="100" style="width: 15%">
      <div class="progress-bar"></div>
    </div>
    <div class="progress" role="progressbar" aria-label="Segment two" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100" style="width: 30%">
      <div class="progress-bar bg-success"></div>
    </div>
    <div class="progress" role="progressbar" aria-label="Segment three" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" style="width: 20%">
      <div class="progress-bar bg-info"></div>
    </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.

<Example code={`<div class="progress" role="progressbar" aria-label="Default striped example" aria-valuenow="10" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar progress-bar-striped" style="width: 10%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Success striped example" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar progress-bar-striped bg-success" style="width: 25%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Info striped example" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar progress-bar-striped bg-info" style="width: 50%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Warning striped example" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar progress-bar-striped bg-warning" style="width: 75%"></div>
  </div>
  <div class="progress" role="progressbar" aria-label="Danger striped example" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar progress-bar-striped bg-danger" style="width: 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.

<Example code={`<div class="progress" role="progressbar" aria-label="Animated striped example" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100">
    <div class="progress-bar progress-bar-striped progress-bar-animated" style="width: 75%"></div>
  </div>`} />
