有些字符在HTML里有特别的含义，比如小于号

这就要说到HTML字符实体(HTML Character Entities)了。

组成

一个字符实体(Character Entity)分成三部分：第一部分是一个&符号，英文叫ampersand；第二部分是实体(Entity)名字或者是#加上实体(Entity)编号；第三部分是一个分号。

比如，要显示小于号，就可以写<或者<。

用实体(Entity)名字的好处是比较好理解，一看lt，大概就猜出是less than的意思，但是其劣势在于并不是所有的浏览器都支持最新的Entity名字。而实体(Entity)编号，各种浏览器都能处理。

注意：Entity是区分大小写的。

如何显示空格

通常情况下，HTML会自动截去多余的空格。不管你加多少空格，都被看做一个空格。比如你在两个字之间加了10个空格，HTML会截去9个空格，只保留一个。为了在网页中增加空格，你可以使用表示空格。
