Examples

Labels

Use the label attribute to label the progress bar and tell assistive devices how to announce it.

<wa-progress-bar value="50" label="Upload progress"></wa-progress-bar>

Custom Height

Use the height CSS property to set the progress bar's height.

<wa-progress-bar value="50" style="height: 6px;"></wa-progress-bar>

Showing Values

Use the default slot to show a value.

<div class="wa-stack">
  <wa-progress-bar value="50" id="progress-bar-demo">50%</wa-progress-bar>

  <div>
    <wa-icon-button pill name="minus" label="Decrease"></wa-icon-button>
    <wa-icon-button pill name="plus" label="Increase"></wa-icon-button>
  </div>
</div>

<script>
  const progressBar = document.querySelector('#progress-bar-demo');
  const subtractButton = document.querySelector('wa-icon-button[name="minus"]');
  const addButton = document.querySelector('wa-icon-button[name="plus"]');

  addButton.addEventListener('click', () => {
    const value = Math.min(100, progressBar.value + 10);
    progressBar.value = value;
    progressBar.textContent = `${value}%`;
  });

  subtractButton.addEventListener('click', () => {
    const value = Math.max(0, progressBar.value - 10);
    progressBar.value = value;
    progressBar.textContent = `${value}%`;
  });
</script>

Indeterminate

The indeterminate attribute can be used to inform the user that the operation is pending, but its status cannot currently be determined. In this state, value is ignored and the label, if present, will not be shown.

<wa-progress-bar indeterminate></wa-progress-bar>
