The progress bar is designed to display the current percent complete for a process. The bar is coded to be flexibly sized through CSS and will scale to fit inside its parent container by default.

A determinate progress bar should only be used in situations where the system can accurately update the current status. A determinate progress bar should never fill from left to right, then loop back to empty for a single process — if the actual status cannot be calculated, an indeterminate progress bar should be used to provide user feedback.

Dependencies

Additional Notes:

  • This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.
