做html网页时，公共部分的代码，求样例

是这样吗

body,div,dl,dd,dt,ul,li,h1,h2,h3,h4,h5,h6,input,form,a,p,textarea{
margin:0px;
padding:0px;
}
ol,ul,li{
list-style:none;
}
a{
text-decoration: none;
display: block;
color:#fff;
}
img{
border:none;
display: block;
}

.clearfloat{
zoom:1;
}
.clearfloat:after{
display: block;
clear:both;
content:"";
visibility:hidden;
height:0;
}
