Css/javascript Start Faded Out By Default, Then Fade In

I'm trying to make a button that causes a green check image to fade in then fade out again. It mostly works, but how do I make the check start out in the faded out position when th

Solution 1:

I'd use display:none in css to hide on page load:

#check {
  display:none;
}

function green_check(check){ //fade in half a sec, hold 2 sec, fade out in 3 sec
    $(check).fadeIn(500, function () {
        $(this).delay(2000).fadeOut(3000);
    });
}

#check {
  display:none;
  width:16px;
  height:16px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" onclick="green_check(getElementById('check'));">Show Check</button>

<img class='five_sec_check' id="check" src='http://neil.computer/s/check.png'/>
