  今天在做小组项目的时候发现登录和注册的使用不是很熟，记录下来：

<script> 
//弹出框中的css部分
input { font-family: Arial, sans-serif;}
.login { width: 270px; margin: 0 auto; padding: 30px 40px; background-color: #f7f7f7;}
.login ul { list-style-type: none;}
.login li { padding: 10px 0; overflow: hidden;}
.login .li3, .login .li5 { text-align: right; font-size: 12px;}
.login .li3 input { width: 13px; height: 13px; margin: 0 3px 0 10px; vertical-align: middle;}
.login .submit { display: block; width: 100%; padding: 6px 0; border: 0 none; color: #fff; background-color: #4d90fe; cursor: pointer;}
#email, #password { width: 214px; padding: 5px; border: 1px solid #ccc;}
.forgot { color: #333;}
//遮罩层css部分
#mask {
                background: #000000;
                opacity: 0.75;
                /*IE不认这个属性*/
                filter: alpha(opacity=75);
                /*这个是为了保证IE兼容*/
                height: 800px;
                width: 100%;
                position: absolute;
                z-index: 999;
                left: 0;
                top: 0;
            }
            
#login {
                position: fixed;
                /*静止定位*/
                /*left: 30%;
                top: 30%;*/
                z-index: 1000;
            }
            
            .loginCon {
                width:350px;
                height: 270px;
            }
            
//弹出框中的关闭部分    #close {
                width: 20px;
                height: 20px;
                position: absolute;
                right: 10px;
                top: 10px;
                cursor: pointer;
                /*border:1px solid red;*/
