ctx.moveTo(5, 100);
ctx.lineTo(395, 100);
ctx.stroke();

ctx.font = "20px Arial"

//Place each word at y=100 with different textBaseline values
ctx.textBaseline = "top";
ctx.fillText("Top", 5, 100);
ctx.textBaseline = "bottom";
ctx.fillText("Bottom", 50, 100);
ctx.textBaseline = "middle";
ctx.fillText("Middle", 120, 100);
ctx.textBaseline = "alphabetic";
