c语言难吗:css的运用

我定义的form表单css 怎么无法运用啊?
本来定义了最小的字体,在dreamve里看的还有css,但在浏览器浏览时却没有css的效果，怎么办啊？？

<style type="text/css">
form {
font-size: xx-small;
font-style: normal;
color: #FF66CC;
text-decoration: line-through;
background-color: #CC3300;
}
-->
</style>
<table width=160 height=100 border=0 cellpadding=0 cellspacing=0 >
<form method="post" name="loginbox" action="userlogin.asp" onsubmit="return checkfor();">
<tr>
<td ></td>
</tr>
<tr>
<td colspan=2 height=5></td>
</tr>
<tr>
<td colspan=2>
 用户名: <input style="BORDER-RIGHT: #ece2d2 1px solid; BORDER-TOP: #ece2d2 1px solid; FONT-SIZE: 8pt; BORDER-LEFT: #ece2d2 1px solid; COLOR: #666666; BORDER-BOTTOM: #ece2d2 1px solid; FONT-FAMILY: verdana" maxlength=20 size=10 name="userid" >
</td>
</tr>
<tr>
<td colspan=2>
 密  码: <input style="BORDER-RIGHT: #ece2d2 1px solid; BORDER-TOP: #ece2d2 1px solid; FONT-SIZE: 8pt; BORDER-LEFT: #ece2d2 1px solid; COLOR: #666666; BORDER-BOTTOM: #ece2d2 1px solid; FONT-FAMILY: verdana" type=password maxlength=12 size=10 name="password">
<input type="hidden" name="Userlogin" value="True">
</td>
</tr>
<tr>
<td colspan=2> 验证码:
<input name="verifycode" type=text id="verifycode" style="BORDER-RIGHT: #ece2d2 1px solid; BORDER-TOP: #ece2d2 1px solid; FONT-SIZE: 8pt; BORDER-LEFT: #ece2d2 1px solid; COLOR: #666666; BORDER-BOTTOM: #ece2d2 1px solid; FONT-FAMILY: verdana" size=6 maxlength=8>
[<%response.write session("verifycode")%>]
</td>
</tr>
<tr>
<td width=70 align="center" valign="bottom"><input type=submit height=23 width=56 border=0 value="登陆"></td>
<td width=88 valign="bottom"> <a href="reg_preview.asp"><img height=23 src="images/left_join.gif" width=78 border=0></a></td>
</tr>
<tr>
<td colspan=2 height=8></td>
</tr>
<tr>
<td background="images/left_login_edge.gif" colspan=2 height=1></td>
</tr>
</form>
</table>
表单里没有这些属性??怎么会没有呢?可以自己定义表单css啊?
