Basically, I'm creating a matching game. When I select an item(eg pear as seen in picture), it will translate to the right. However, it will end up being on top of the line drawn on the canvas. I want the line to be on top of the image and not the other way round.
I've tried using z-index for canvas to be greater than img but it does not work. Any idea how to fix this?
HTML
<table class="first">
<tr>
<td>
<ul class="firstleft">
/*some images to be filled here*/
</ul>
</td>
<td>
<canvas id="myCanvas" resize></canvas>
</td>
<td>
<ul class="firstright">
/*some images to be filled here*/
</ul>
</td>
</tr>
</table>
CSS
img {
z-index: 1;
}
canvas {
z-index: 20;
}
JS
var canvas = document.getElementById('myCanvas');
ctx = canvas.getContext("2d")
ctx.lineWidth = 6;
ctx.strokeStyle = "#333";
/* Drawing part using an example*/
ctx.beginPath();
ctx.moveTo(100, 250);
ctx.bezierCurveTo(150, 100, 350, 100, 400, 250);
ctx.stroke();
in that case it works
var canvas = document.getElementById('demo'), /// canvas element
ctx = canvas.getContext('2d'), /// context
line = new Line(ctx), /// our custom line object
img = new Image; /// the image for bg
ctx.strokeStyle = '#fff'; /// white line for demo
/// start image loading, when done draw and setup
img.onload = start;
img.src = 'http://i.imgur.com/O712qpO.jpg';
function start() {
/// initial draw of image
ctx.drawImage(img, 0, 0, demo.width, demo.height);
/// listen to mouse move (or use jQuery on('mousemove') instead)
canvas.onmousemove = updateLine;
}
