代码见下面？为什么list-style:none不起作用呀？

没ul 的默认等级高。
为何要设在body上？
你设置在body上面，那么之后的ul之内是去继承这个body的设置，继承来的东西，会被本身携带的属性覆盖的。
好复杂的问题~
可不可以这样理解：
ul的默认样式属于内联样式表
head标签中的 body{……}，属于内部样式表
而 内部样式表 的优先级要低于 内联样式表
如果没反映的话 最好就加在div里的css style 里这样最稳定了
写在ul上即可……
综合楼上那位朋友所说得出以下结论：
写在body上理论上是可以被body里面的元素继承，但是在CSS里继承的权限是最低的，所以会被UL自身的默认样式覆盖，这样的代码一般都直接写给UL
ul{
list-style:none;
}
谢谢，好像明白了。
