# html转义字符

# 转义字符串的组成

转义字符串(Escape Sequence),即字符实体(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。

提示

实体名称(Entity)是区分大小写的。

备注:同一个符号,可以用“实体名称”和“实体编号”两种方式引用,“实体名称”的优势在于便于记忆,但不能保证所有的浏览器都能顺利识别它,而“实体编号”则没有这种担忧,但它实在不方便记忆。
