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.
Default Progressbar
 The 
                                                .progress is 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. You can add some role and aria attributes to make it accessible. Various height
 Control the height by adding style 
                                                height:"value" to .progress element or you could use the prebuilt classes for a more uniform structure, .progress-xs, .progress-sm, .progress-md, .progress-lg, .progress-xl
                                                Label display
 Add labels to your progress bars by placing text within the 
                                                .progress-bar

                                                .progress class Multiple bars
 Include multiple progress bars in a progress component if you need 
                                                Gradient backgrounds
 Control the background by adding avaialble color pallets to 
                                                .progress class Striped backrounds
 Add 
                                                .progress-bar-striped to any .progress-bar to apply a stripe via CSS gradient over the progress bar’s background color Animated bars
 The striped gradient can also be animated. Add 
                                                .progress-bar-animated to .progress-bar to animate the stripes right to left via CSS3 animations.
