Layers.......

a: Document Object Model ~
b: a Photoshop document

What:

"A good analogy for this: the HTML DOM is like a Photoshop document while HTML5 Canvas is like a PNG. Photoshop documents have layers that you can interact with, modify, and remove. PNG images, on the other hand, contain a single "flat" file of pixels. You can't "remove" or "modify" elements from a PNG. You can only change the color values of each individual pixel."
