So I have a `canvas` which I want to draw multiple images onto and then layer them, so; first image would have `opacity: 0.5;` image two would have `opacity: 0.7` and then third being `opacity: 0.3;`. My question.

Should I have multiple canvas elements on one page and then `position: absolute;` them on top of each other or try something else?

Just wondering A. Performance and B. is this semantically correct? Thanks.
