Hide div after a few seconds

Question

I was wondering, how in jquery am I able to hide a div after a few seconds? Like Gmail's messages for example.

I've tried my best but am unable to get it working.

Answer 1

This will hide the div after 1 second (1000 milliseconds).

setTimeout(function() {
    $('#mydiv').fadeOut('fast');
}, 1000); // <-- time in milliseconds

#mydiv{
    width: 100px;
    height: 100px;
    background: #000;
    color: #fff;
    text-align: center;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="mydiv">myDiv</div>

If you just want to hide without fading, use hide().
