  +  ### Custom Events with EventEmitter
   
     Directives typically raise custom events with an Angular [EventEmitter](../api/core/index/EventEmitter-class.html).
     A directive creates an `EventEmitter` and exposes it as a property.

    ## Attribute, class, and style bindings
    The template syntax provides specialized one-way bindings for scenarios less well suited to property binding.
  
    ### Attribute binding
    We can set the value of an attribute directly with an **attribute binding**.
  .l-sub-section
    :marked
  
negative.code:     we generally prefer the [NgClass directive](#ngClass) for managing multiple class names at the same time.

    ### Style Binding
  
    We can set inline styles with a **style binding**.
