| Decorator | Element | |
|---|---|---|
| Purpose | Give existing content new behavior and/or appearance. | Create new content building blocks. |
| Use Cases |
|
|
| Identity | Does not change the identity of the element. | Creates a new type of element. |
| Lifetime | Transient, added and removed dynamically. | Permanent, originates with the element’s creation and exists through the lifetime. |
| Content Environment | Foreign document or limited control of content | Full control of content |
| Shadow Tree | Each decorator must have its own shadow subtree, and the aggregate shadow tree of an element is composed out of these subtrees. | Only one tree, initialized as the element is created. |
| DOM API | Should avoid adding any extra methods or properties to the DOM element that’s being decorated. | Explicitly interested in exposing methods or properties on the DOM element as its API. |
