I have one canvas element generated by javascript, here is the code: http://jsfiddle.net/mtvzgnmm/
<div id="circle"></div>
<script>
$('#circle').circleProgress({
value: 0.75,
size: 400,
fill: {
gradient: ["#e57569"]
}
});
</script>
But I have this #circle div in another div with 500px width, and I want to create mobile version too, but I can't make my canvas 100% wide...
