这样水平方向在中间了，怎么让它也处于竖直的*呢？
7 个解决方案
#1
在<body>和</body>之间插入表格<table width=100% height=100% cellpadding=0 cellspacing=0><tr><td align="center"></td></tr></table>
这样，<td></td>里面的东西全部就居中了
或者你在表单的外层加上<div align="center>跟</div>

#2
竖起的*在<body>和</body>之间插入表格<table width=100% height=100% cellpadding=0 cellspacing=0><tr><td align="center" valign="middle"></td></tr></table>把<form>……</form>放在<td></td>里面
#3
<table align='center'><form></form></table>
或者用层来定义
或者用层来定义
#4
valign="middle" 看看 form标签有没有这个属性
#5
若要表單永遠都在网页的正中间,那得放在層里,并用腳本控制它
#6
<body>
<table cellpadding=0 cellspacing=0 border=0 width=100% height=100%>
<tr><td align="center" valign="middle">
<form>.............</form>
</td>
</tr>
</table>
</body>
这样我不相信不会在中间
