--- layout: docs title: Progress description: Documentation and examples for using Bootstrap custom progress bars featuring support for stacked bars, animated backgrounds, and text labels. group: components toc: true --- {{< callout info >}} **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 `` 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 >}}

{{< /example >}} ## 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 >}}

{{< /example >}} ### 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 >}}

{{< /example >}} ## Labels Add labels to your progress bars by placing text within the `.progress-bar`. {{< example >}}

{{< /example >}} ### 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 warning >}} **Accessibility warning:** Long labels may not be fully accessible with this method. As it relies on the text color having the right contrast ratio with both the `.progress` and `.progress-bar` background colors, your color palette could be incompatible with this approach. 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 >}}

{{< /example >}} {{< callout info >}} {{< partial "callouts/warning-color-assistive-technologies.md" >}} {{< /callout >}} 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 >}}

{{< /example >}} ## 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 >}}

{{< /example >}} ## Striped Add `.progress-bar-striped` to any `.progress-bar` to apply a stripe via CSS gradient over the progress bar's background color. {{< example >}}

{{< /example >}} ## 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 >}}

{{< /example >}} ## CSS ### Variables {{< added-in "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. {{< scss-docs name="progress-css-vars" file="scss/_progress.scss" >}} ### Sass variables {{< scss-docs name="progress-variables" file="scss/_variables.scss" >}} ### Keyframes Used for creating the CSS animations for `.progress-bar-animated`. Included in `scss/_progress-bar.scss`. {{< scss-docs name="progress-keyframes" file="scss/_progress.scss" >}}
