常用base.css

ul {
list-style: none;
}
a {
text-decoration: none;
}

body,
h1,
h2,
h3,
h4,
h5,
h6,
p,
ul,
ol,
form {
margin: 0;
padding: 0;
}
html,
body {
width: 100%;
height: 100%;
background: #fff;
font-size: 12px;
font-family: Microsoft YaHei ;
SimSun, Arial, Helvetica, sans-serif;
}
.fl {
float: left;
}
.fr {
float: right;
}
img {
border: none;
}

CSS编码的时候，注意保存utf-8格式，font-family的中文字体，替换为英文字体
