{{< 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 `<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 >}}
|
|
<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>
|
|
{{< /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 >}}
|
|
<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>
|
|
{{< /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 >}}
|
|
<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>
|
|
{{< /example >}}
|
|
|
|
## Labels
|
|
|
|
Add labels to your progress bars by placing text within the `.progress-bar`.
|
|
|
|
{{< example >}}
|
|
<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>
|
|
{{< /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 >}}
|
|
<div class="progress" role="progressbar" aria-label="Example with label" aria-valuenow="10" aria-valuemin="0" aria-valuemax="100">
|
|
<div class="progress-bar overflow-visible text-dark" style="width: 10%">Long label text for the progress bar, set to a dark color</div>
|
|
</div>
|
|
{{< /example >}}
|
|
|
|
## Backgrounds
|
|
|
|
Use background utility classes to change the appearance of individual progress bars.
|
|
|
|
{{< example >}}
|
|
<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>
|
|
{{< /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 >}}
|
|
<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%">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 text-dark" 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 bg-warning text-dark" 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 bg-danger" style="width: 100%">100%</div>
|
|
</div>
|
|
{{< /example >}}
|
|
|
|
Alternatively, you can use the new combined [color and background]({{< docsref "/helpers/color-background" >}}) helper classes.
|
|
|
|
{{< example >}}
|
|
<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>
|
|
{{< /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 >}}
|
|
<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>
|
|
{{< /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 >}}
|
|
<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>
|
|
{{< /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 >}}
|
|
<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>
|
|
{{< /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.
