的后边按了下回车换行了吗?按道理说应该“这样”两个字显示在第二行。。而第一行是空白的,可是结果不是  <br> 哪位对这个了解的朋友希望帮下忙。。。我百思不得其解。。。度娘也找了都说的不是这个问题- -  <br> <h2 id="回复讨论-解决方案">回复讨论(解决方案)</h2> <p class="sougouAnswer">  xml标准写法  <br> </p><pre class="brush:php;toolbar:false">  <br> 这样  <br>

那浏览器到底是如何解析pre的呢?为什么连

是这意思

html的换行不是指的是你回车一下就可以了。

  <br> 这样

仅仅指的是要显示“这样”两个字。
如果要换行的话,就必须再加上一个回车
  
<br> 这样
