Shadow trees |
w3c 中关于 Shadow tress 是这样说的：
- 文档树是根节点为文档(document)的节点树. (A document tree is a node tree [DOM] whose root node is a document.)
- 任何元素都能拥有一个按顺序排列的关联0到多个节点树的列表.(Any element can have an associated ordered list of zero or more node trees.)
- 该元素作为此节点树的宿主，如果这个节点树在该元素的节点树列表中.(An element hosts a node tree if the node tree is a member of this associated list.)
- shadow host就一个元素 hosts 一个或多个节点树.(A shadow host is an element that hosts one or more node trees.)
- shadow root 是一个 shadow tree 的根节点。
- 如果某个shadow host, hosts 了多个 shadow tree， 最近添加的成为 younger，越早越 older。
