  </div>
</div>

    </div>
  </div>

Best Practices

    For progress bars, include text to show percentage completion or task names.
  2. Color Coding
    Use colors to indicate urgency or importance (e.g., red for errors, green for success).
  3. Test Responsiveness
    Ensure bars display properly across all devices.
  4. Keep Bars Minimalistic
    Avoid overloading bars with excessive content or effects.
