--- title: Progress description: Documentation and examples for using Bootstrap custom progress bars featuring support for stacked bars, animated backgrounds, and text labels. toc: true --- **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]]) ## 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 `` 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`.
`} /> ### 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.
`} /> ## Labels Add labels to your progress bars by placing text within the `.progress-bar`.

`} /> ### 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]]). 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.
`} /> 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.

`} /> ## 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.
`} /> ## Striped Add `.progress-bar-striped` to any `.progress-bar` to apply a stripe via CSS gradient over the progress bar’s background color.
`} /> ## 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.
`} /> ## CSS ### Variables 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. ### Sass variables ### Keyframes Used for creating the CSS animations for `.progress-bar-animated`. Included in `scss/_progress-bar.scss`.
