mobile view booking and login form

i managed to create a working mobile view for the booking form, not showing the login on a smartphone. use this custom css for a start:

@media (max-width: 768px) {
.em-booking-form-details {
float: none;
display: block;
width: 100%;
}
div.em-booking-login {
float: left;
margin: 30px 0;
padding:0px;
display: block;
width: 100%;
}
}`
