为什么结果会向下移了10px

<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>practice</title>
<style>

body{background:black} #cvs{background:white}

</style>
<script>
window.onload=function(){

var oCvs=document.getElementById("cvs"); var oGc=oCvs.getContext("2d");   oGc.font="60px impact"; oGc.textBaseline="top"; oGc.fillText("妙味课堂",0,0);

}
</script>
</head>
<body>

<canvas id="cvs" width="400px" height="400px"></canvas>

</body>
</html>
