段落不与div环绕。

Question

我感到困惑的是，在90%的时间里，包装都是有效的--但在特定的构词法中却有所突破。

它基于css技巧“不要过度考虑网格”的博客文章，所以在本教程的末尾，问题似乎已经存在了。

如你所见，以下段落如下：

BIDFIK高级roolbool高级rackorack op lopski deenoopaloombajandalop me jandalop pep google lopski完美偏好组调用，稍后再进行脚激励通用。

从父div流出。为什么？

Answer 1

这是看不见的字符/隐藏的字符。

我使用Vim命令删除了它：

:%s/\%xa0/ /gc

其中xa0是char (0xA0)的十六进制代码。
