大家帮我看看,下面这段CSS有什么问题吗?body的样式一直没效果
/*第一行没有作用,这是为什么呢?*/body{background: #fff; font-size: 13px; font-family: Microsoft Yahei; color: #000;}body,p,ul,li,ol,h1,h2,h3,h4,h5{margin: 0; padding: 0;}ul,li,ol{list-style-type: none;}a{text-decoration: none;}input{border: 1px solid #ccc; outline: none;}img{border: 0;}
font-family: "Microsoft Yahei";
font-family: "Microsoft Yahei";
charset: "utf-8";/*分号没加,栽在这儿了*/
