--- 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 >}} 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" >}}), but make sure to also define an explicit [text color]({{< docsref "/utilities/colors#colors" >}}) so the text remains readable. Be aware though that currently this approach does not take into account [color modes]({{< docsref "/customize/color-modes" >}}). {{< example >}}

{{< /example >}} ## 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. {{< 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" >}}
