여기까지 했는데 화면에 네모가 안 나오네요
getcontext, fillstyle, fillrect도 적용이 안되고 그냥 글자로 인식된거 같은데 이유가 뭘까요?

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');
canvas.width = window.innerWidth - 100;
canvas.height = window. innerHeight - 100;
ctx.fillStyle = 'green';
ctx.fillrect(10,10, 100,100);
