Progress Bars are essential because they inform users about ongoing processes, such as file uploads, loading screens, or data processing. They enhance user experience by providing feedback, indicating how much of a task is completed and how long it may take.

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

  <div class="progress-bar bg-success" role="progressbar" style="width: 100%;">100%</div>
</div>

<div class="progress">

Stacked progress bars can show multiple progress levels within the same container, allowing for clear representation of various tasks. To create a stacked progress bar, you can nest multiple .progress-bar elements within a single .progress container.

<div class="progress">
  <div class="progress-bar bg-success" role="progressbar" style="width: 35%;">Task 1: 35%</div>
  <div class="progress-bar bg-info" role="progressbar" style="width: 25%;">Task 2: 25%</div>
