Progress

Angular Bootstrap 5 Progress component

Documentation and examples for using custom progress bars featuring support for stacked bars, animated backgrounds, and text labels.

Basic example

Use a progress bar element to display a percentage completion rate by using an inline style and the utility classes.

<div class="progress">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 75%"
    aria-valuenow="75"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>

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, 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.
  • We use the inner .progress-bar to indicate the progress so far.
  • The .progress-bar requires an inline style, utility class, or custom CSS to set their width.
  • The .progress-bar also requires some role and aria attributes to make it accessible.

Put that all together, and you have the following examples.





<div class="progress">
  <div
    class="progress-bar"
    role="progressbar"
    aria-valuenow="0"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 25%"
    aria-valuenow="25"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 50%"
    aria-valuenow="50"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 75%"
    aria-valuenow="75"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 100%"
    aria-valuenow="100"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>

MDB provides a handful of utilities for setting width. Depending on your needs, these may help with quickly configuring progress. 

<div class="progress">
  <div
    class="progress-bar w-75"
    role="progressbar"
    aria-valuenow="75"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>

Labels

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

To make the label visible you need to set a proper height to the bar.

25% 
<div class="progress" style="height: 20px">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 25%"
    aria-valuenow="25"
    aria-valuemin="0"
    aria-valuemax="100"
  >
    25%
  </div>
</div>

Height

We only set a height value on the .progress, so if you change that value the inner .progress-bar will automatically resize accordingly. 


<div class="progress" style="height: 1px">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 25%"
    aria-valuenow="25"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress" style="height: 20px">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 25%"
    aria-valuenow="25"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>

Colors

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




<div class="progress">
  <div
    class="progress-bar bg-success"
    role="progressbar"
    style="width: 25%"
    aria-valuenow="25"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar bg-info"
    role="progressbar"
    style="width: 50%"
    aria-valuenow="50"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar bg-warning"
    role="progressbar"
    style="width: 75%"
    aria-valuenow="75"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar bg-danger"
    role="progressbar"
    style="width: 100%"
    aria-valuenow="100"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>

Multiple bars

Include multiple progress bars in a progress component if you need.

<div class="progress">
  <div
    class="progress-bar"
    role="progressbar"
    style="width: 15%"
    aria-valuenow="15"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
  <div
    class="progress-bar bg-success"
    role="progressbar"
    style="width: 30%"
    aria-valuenow="30"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
  <div
    class="progress-bar bg-info"
    role="progressbar"
    style="width: 20%"
    aria-valuenow="20"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>

Striped

Add .progress-bar-striped to any .progress-bar to apply a stripe via CSS gradient over the progress bar’s background color. 





<div class="progress">
  <div
    class="progress-bar progress-bar-striped"
    role="progressbar"
    style="width: 10%"
    aria-valuenow="10"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar progress-bar-striped bg-success"
    role="progressbar"
    style="width: 25%"
    aria-valuenow="25"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar progress-bar-striped bg-info"
    role="progressbar"
    style="width: 50%"
    aria-valuenow="50"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar progress-bar-striped bg-warning"
    role="progressbar"
    style="width: 75%"
    aria-valuenow="75"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>
<div class="progress">
  <div
    class="progress-bar progress-bar-striped bg-danger"
    role="progressbar"
    style="width: 100%"
    aria-valuenow="100"
    aria-valuemin="0"
    aria-valuemax="100"
  ></div>
</div>

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. 

<div class="progress">
  <div
    class="progress-bar progress-bar-striped progress-bar-animated"
    role="progressbar"
    aria-valuenow="75"
    aria-valuemin="0"
    aria-valuemax="100"
    style="width: 75%"
  ></div>
</div>

Progress - API

CSS variables

As part of MDB’s evolving CSS variables approach, progress 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.

// .progress
--#{$prefix}progress-height: #{$progress-height};
@include rfs($progress-font-size, --#{$prefix}progress-font-size);
--#{$prefix}progress-bg: #{$progress-bg};
--#{$prefix}progress-border-radius: #{$progress-border-radius};
--#{$prefix}progress-box-shadow: #{$progress-box-shadow};
--#{$prefix}progress-bar-color: #{$progress-bar-color};
--#{$prefix}progress-bar-bg: #{$progress-bar-bg};
--#{$prefix}progress-bar-transition: #{$progress-bar-transition};

SCSS variables

$progress-height: 4px;
$progress-font-size: $font-size-base * 0.75;
$progress-bg: $gray-200;
$progress-border-radius: $border-radius;
$progress-box-shadow: $box-shadow-inset;
$progress-bar-color: $white;
$progress-bar-bg: $primary;
$progress-bar-animation-timing: 1s linear infinite;
$progress-bar-transition: width 0.6s ease;
