替代HTML5中的标签？(Alternative to tag in HTML5?)

 我今天正在阅读有关Shadow DOM的内容，作者使用此<content>标记从主机中提取textContent 。 
 

 教程 ： http ： //www.html5rocks.com/en/tutorials/webcomponents/shadowdom/ 
 

 当我查找它时，我发现<content>标记已被弃用，应该避免使用。 我现在应该怎么做？ 我应该学会使用<content>标签吗？ 来源 ： Mozilla文档 

I was reading today about Shadow DOM, where the author used this <content> tag to pull in textContent from the host.
 

Tutorial: http://www.html5rocks.com/en/tutorials/webcomponents/shadowdom/
 

When I looked it up, I found that the <content> tag has been deprecated and should be avoided. What should I do now? Should I learn to use <content> tag or not? Source:  Mozilla Documentation

 相同的文档（ Mozilla FireFox ）声明： 
 

 
 
 它现在已被<slot>元素取代。 
 

 

 使用<slot>元素。 当某些东西被弃用时，你不应该再使用它了。 （ Mozilla也说明了这一点。）弃用意味着它不再被批准/不批准。 

The same documentation (Mozilla FireFox) states:
 

 
 
It has now been replaced by the <slot> element.
 

 

Use the <slot> element. When something is deprecated, you should no longer use it. (Mozilla also states this.) Deprecated means it is no longer approved of/disapproved.
