Hey guys I'm a little new to this and I need some help. I need to make a visual force page using html5 and the <canvas> element. The canvas will create a modifiable box in which a user can draw something and then that will be stored elsewhere as a JSON file to be recalled later. I need to know if and how this would be possible. I can get a box to show up but I can't get it to be editable ( I can't draw inside of it). 

HELP PLEASE
