Drawing to the background <p>I'm creating a website that lets the user draw to the background with a color he chooses. I also want to let the user to change the background color with a hex color picker tool.</p> <p>The latter is easy but how can I let the user draw to the background? Is it possible to use canvas as the background?</p> <p>Should I create the whole background entire of small divs which color I would change when the user is drawing?</p>
