你是说邮箱那个不能靠右边吗?你把错误信息挪到下面一行就可以了。
style="float:right" text-align:right 试试
.field .field { position: relative;}.field .help { position: absolute; width: 300px; text-align: left; padding-left: 12px;} 解决方案：
1、像这种表单布局，个人推荐用table
2、像你这种不右对齐，其实是因为你没给提示信息一个固定的块存放
3、把提示信息做相对定位，这样就解决就不会因没分配空间，而把左边的元素挤过去了。
.field .field { position: relative;}.field .help { position: absolute; width: 300px; text-align: left; padding-left: 12px;}提示用 placehold 你懂得
.field .field { position: relative;}.field .help { position: absolute; width: 300px; text-align: left; padding-left: 12px;}text-ailgn:right 试试
