Browser Support
Internet Explorer 9, Firefox, Opera, Chrome, and Safari support the textAlign property.
Note: Internet Explorer 8 and earlier versions, do not support the <canvas> element.
Definition and Usage
The textAlign property sets or returns the current alignment for text content, according to the anchor point.
Normally, the text will START in the position specified, however, if you set textAlign="right" and place the text in position 150, it means that the text should END in position 150.
Tip: Use the fillText() or the strokeText() method to actually draw and position the text on the canvas.
