Property binding

• When binding to a style using [style.{style prop}], the computed value should not contain any semicolon at the end of the value (if it is a string)

Property getters and setters in interfaces

To tell that a class which implements an interface should only have a property getter, the property should be defined as readonly in the interface. To allow the setter too, it is enough to specify the property without any modifier. Getters and setters in a class which implements an interface can be overridden by subclasses.

Reference to directives in components

To get the reference to any directive associated to a component, inject it into the component's constructor.

Component styling

To apply a style to the html component element itself the :host selector can be used to target it.
