转义HTML是指将特殊字符转换为HTML实体,以便在网页中正确显示这些字符。在编写HTML代码时,如果直接在文本中包含一些特殊字符,比如""、"&"等,会导致浏览器误解该字符的含义,导致页面错误或不完整地显示。因此,在使用这些特殊字符时,我们需要将其转义为HTML实体,以确保页面能够正常被浏览器解析。

下面是一些常见的HTML实体及其对应的字符:

  • > – 大于号 (>)
  • & – 和号 (&)
  • " – 双引号 (")
  • ' – 单引号 (')

这些实体都是以"&"开头,以";"结尾的字符串,所以在使用它们时,只需要将特殊字符替换为相应的实体即可。例如,如果要在网页中显示"

<p>这是一个小于号:<</p>

这样就能在页面中正确显示小于号。

除此之外,还有一些特殊字符,比如空格、换行等,也需要转义为HTML实体。例如,要在页面上输出一个空格,可以使用 实体,如下所示:

<p>这是一个空格:hello world</p>

这样就能在页面中输出一个空格。

在Web开发过程中,转义HTML实体是一个重要的技能。如果在写HTML代码时没有正确转义特殊字符,可能会导致页面错误或不完整地显示,从而降低用户体验。因此,我们需要在编写HTML代码时注意转义特殊字符,以确保页面能够正常显示。
