You can use animation example.

Set the animation-delay to the time you want. Make sure you use animation-fill-mode: forwards to stop the animation.

#signup-response{
    width: 50%;
    margin-left: auto;
    margin-right: auto;
    text-align: center;
    background-color: #FF0000;
    margin-top: 20px;

     animation:signup-response 0.5s 1;
    -webkit-animation:signup-response 0.5s 1;
    animation-fill-mode: forwards;

    animation-delay:2s;
    -webkit-animation-delay:1s; /* Safari and Chrome */
    -webkit-animation-fill-mode: forwards;

} 

@keyframes signup-response{
    from {opacity :1;}
    to {opacity :0;}
}

@-webkit-keyframes signup-response{
    from {opacity :1;}
    to {opacity :0;}
}
