## 取消注释HTML
|
|||
|
|
|
|||
|
|
评论主题在开始时通常有点令人困惑。 看看这个例子：
|
|||
|
|
```
|
|||
|
|
<!-- This is a commented block.
|
|||
|
|
It doesn't matter how long it is, if it has <h1>HTML elements</h1> in it or if it develops
|
|||
|
|
into
|
|||
|
|
few lines,
|
|||
|
|
everything between the first weird series of character and the last is commented out -->
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
你也可以在线使用评论： `<!-- Uh, I does not exists! -->`在这里！
|
|||
|
|
|
|||
|
|
唯一要考虑的是，当你看到这组char `<!--`从那里看到的所有东西都被注释掉了，因为你找到了镜面反射`-->` ;这些是HTML元素的开始和结束标记！
|
|||
|
|
|
|||
|
|
##### 取消注释
|
|||
|
|
|
|||
|
|
取消注释意味着从注释文本中取出：取消注释后面句子的h3元素（全部注释掉）：
|
|||
|
|
```
|
|||
|
|
<!-- <h1>Comment header</h1> <h3>Comment subtle</h3> <article>I am the text of the comment</article> -->
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
就像这样简单：
|
|||
|
|
```
|
|||
|
|
<!-- <h1>Comment header</h1> --> <h3>Comment subtle</h3> <!-- <article>I am the text of the comment</article> -->
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
注意如何在h3 HTML元素之前添加一个结束注释标记（ `-->` ）以匹配句子开头的开始注释标记，并在它之后添加一个开始注释标记（ `<!--` ）以匹配结束最后的标签：这样你就创建了两个内联注释，一个在h3元素之前，一个在！之后。
|
|||
|
|
|
|||
|
|
如果你想取消注释一切都更容易：
|
|||
|
|
```
|
|||
|
|
<h1>Comment header</h1> <h3>Comment subtle</h3> <article>I am the text of the comment</article>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
只需删除评论的开始和结束标记即可。
