Based on @p.cambell answer and the implementation with css, I wrote this code in asp.net for a login popup screen:
css
.flotante-login {
border:solid 2px #b7ddf2;
border-radius: 5px;
padding: 15px;
background:#ebf4fb;
}
.loginBox {
margin: 0 auto;
width: 400px;
padding: 10px;
}
#login{
}
#login h1 {
font-size: 18px;
font-weight: bold;
margin-bottom: 15px;
}
#login p{
font-size:11px;
color:#666666;
margin-bottom:20px;
border-bottom:solid 1px #b7ddf2;
padding-bottom:10px;
}
#login label{
display:block;
font-weight:bold;
text-align:right;
width:140px;
float:left;
}
#login .small{
color:#666666;
display:block;
font-size:11px;
font-weight:normal;
text-align:right;
width:140px;
}
#login input{
float:left;
font-size:12px;
padding:4px 2px;
border:solid 1px #aacfe4;
width:200px;
margin:2px 0 20px 10px;
}
#login a{
clear:both;
width:125px;
padding: 10px;
background-color: #E2B66B;
color:#FFFFFF;
text-align:center;
text-decoration: none !important;
line-height:30px;
font-weight:bold;
color: #FFF !important;
border-radius: 5px;
}
