Toasts
Toasts are lightweight notifications designed to mimic the push notifications that have been popularized by mobile and desktop operating systems
Initialization
Initialize via JavaScript:
$('.toast').toast(option)
						  	Markup
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.
							        Toast!
							        11 mins ago
							        
							    
							    
							        Hello, world! This is a toast message.
							    
							<div class="toast fade show" role="alert" aria-live="assertive" aria-atomic="true">
    <div class="toast-header">
        <strong class="mr-auto">Toast!</strong>
        <small>11 mins ago</small>
        <button type="button" class="close ml-3" data-dismiss="toast" aria-label="Close">
        <span aria-hidden="true">✕</span>
        </button>
    </div>
    <div class="toast-body">
        Hello, world! This is a toast message.
    </div>
</div>
						  	Contextual toasts
Use background and text utility classes to create a contextual toast.
