CSS3 animation fadeOut

Question

I'm trying to dissappear Bootstrap Alert after 3seconds. I made it, but it just dissapears and keeps the height of div. Can I remove that div with CSS only? I tried display:none; and it also didn't work. I need help.

This is what I did:

CSS:

.alert-success {
    -webkit-animation: fadeOut 3s linear forwards;
    animation: fadeOut 3s linear forwards;
}


@-webkit-keyframes fadeOut {
    0%   {opacity: 1;}
    70%  {opacity: 1;}
    90% {opacity: 1;-webkit-transform: translateY(0px);}
    100% {opacity: 0;-webkit-transform: translateY(-30px);}
}

HTML:

<div class="alert alert-success">
   Well done! You successfully read this important alert message.
</div>

Thanks in advance
