css 清除一些默认的设置

一、input标签的placeholder的设置

input::-webkit-input-placeholder{ /*WebKit browsers*/
  //重置样式
}

input::-moz-input-placeholder{ /*Mozilla Firefox*/
  //重置样式
}

input::-ms-input-placeholder{ /*Internet Explorer*/
  //重置样式
}

　　
二、input标签的获得焦点的边框设置

//在input的css中加
outline：none
或
outline:medium;

input{ outline:medium;}
 /*获取焦点*/
input:focus{
  border: 1px dolid #EEE;
 }

　　
三、去掉列表的默认样式

li {
	list-style-type: none;
}
ol, ul {
	list-style: none;
}
