<Callout>
**New markup in v5.3.0 —** We’ve deprecated the previous HTML structure for progress bars and replaced it with a more accessible one. The previous structure will continue to work until v6. [See what’s changed in our migration guide.]([[docsref:/migration#improved-markup-for-progress-bars]])
</Callout>

## 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.

## 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={`

`} />

### 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={`

`} />

## Labels

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

<Example code={`
    
25%
  
`} />

### 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.

## Backgrounds

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

<Example code={`

`} />

<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={`
    
25%

50%

75%

100%
  
`} />

## 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={`

`} />

## 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={`

`} />

## 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={`

`} />

## CSS

### Variables

<AddedIn version="5.2.0" />

As part of Bootstrap’s evolving CSS variables approach, progress bars now use local CSS variables on `.progress` for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

<ScssDocs name="progress-css-vars" file="scss/_progress.scss" />

### Sass variables

<ScssDocs name="progress-variables" file="scss/_variables.scss" />

### Keyframes

Used for creating the CSS animations for `.progress-bar-animated`. Included in `scss/_progress-bar.scss`.

<ScssDocs name="progress-keyframes" file="scss/_progress.scss" />
