placing a div over a canvas in html5 - css

Question

I am trying to place a div element over a canvas (it is for a game) on the center of my page. It is about a startscreen that I want to show over the canvas, before starting the game(this startscreen has options like "Play game", "Settings" etc). The problem is that I cannnot get this done, I have searched a lot on Google, I have seen a lot of examples, but none of them seems to be working for me. Here is my code:
<div id="gamecontainer">
<canvas id="myCanvas" width="800" height="600">
Sorry, <strong>CANVAS</strong> is not supported by your browser. Get a more recent one to play my game!
</canvas>
<div id="gamestartscreen" class="gamelayer">
<img src="images/icons/play.png" alt="Play Game" onclick="alert('ceve');"><br>
<img src="images/icons/settings.png" alt="Settings">
</div>
</div>
here is the css:
#gamecontainer {
width: 800px;
height: 600px;
background-color: beige;
border: 1px solid black;
position: relative;
margin: 0 auto;
}
.gamelayer {
width: 800px;
height: 600px;
position: absolute;
display: none;
z-index: 0;
}
/* Screen for the main menu (Like Play, Settings, etc.) */
#gamestartscreen {
position: relative;
margin: 0 auto;
}
#gamestartscreen img {
margin: 10px;
cursor: pointer;
}
Could someone please tell me where I am doing it wrong?

Answer 1

The problem was that the canvas layer was in its native static positioning, while the gamestart div was in relative positioning with no positive z-index value. Essentially, you jut have to set the canvas element to position: absolute or even position: relative, while having a >1 z-index for the startstreen div. This JSFiddle should make it all clear.
