如果有错误消息我有以下代码.然后登录表单的边缘顶部应为"0",对于第一个错误,msg margin top应为"70px".
<span class="portlet-msg-error"> You have entered invalid data. Please try again. </span>
<span class="portlet-msg-error"> Authentication failed. Please try again.</span>
<div class="login-form" style="margin-top: 70px;"> Form Display here </div>
