css初始化问题_html/css_WEB-ITnose

#main{
width:1024px;
height:900px;
background:#000000;
}
#top{
background: url(image/bground1.jpg);
}
#lside{
width:700px;
height:700px;
float:left;
background:#fff000;
}
#rside{
width:300px;
height:700px;
float:right;
background:#ccccdd;
}

如果没有css初始化的话，#main就工作，加上之后就不工作了，这是为什么呢？



下面是初始化的代码：
@CHARSET "UTF-8";
body, h1, h2, h3, h4, h5, h6, hr, p, blockquote, dl, dt, dd, ul, ol, li, pre, form, fieldset, legend, button, input, textarea, th, td { margin:0; padding:0; }
body, button, input, select, textarea { font:12px/1.5tahoma, arial, \5b8b\4f53; }
h1, h2, h3, h4, h5, h6{ font-size:100%; }
address, cite, dfn, em, var { font-style:normal; }
code, kbd, pre, samp { font-family:couriernew, courier, monospace; }
small{ font-size:12px; }
ul, ol { list-style:none; }
a { text-decoration:none; }
a:hover { text-decoration:underline; }
sup { vertical-align:text-top; }
sub{ vertical-align:text-bottom; }
legend { color:#000; }
fieldset, img { border:0; }
button, input, select, textarea { font-size:100%; }
table { border-collapse:collapse; border-spacing:0; }

不可能的,两个互不影响.
