Basic
Toasts are as flexible as you need and have very little required markup. At a minimum, we require a single element to contain your “toasted” content and strongly encourage a dismiss button.

Toasts are slightly translucent, too, so they blend over whatever they might appear over.

                                    Stacking
You can stack toasts by wrapping them in a toast container, which will vertically add some spacing.

                                      Color schemes
Building on the above example, you can create different toast color schemes with our color and background utilities. Here we’ve added .bg-primary and .text-white to the .toast, and then added .btn-close-white to our close button. For a crisp edge, we remove the default border with .border-0.
                                          Hello, world! This is a toast message.
