I actually did read your post and it read to me as if it put in the background to get around some sort of issue with how you took the screenshot, but had still placed the images and text on top. What you wrote was:

    So it kind of cheated, though it clearly felt angst about
    it. After trying a few ways to get the stars to line up 
    perfectly, it just gave up and copied the screenshot in 
    as the background image, then overlaid the rest of the 
    HTML elements on top.

Which is only "kind of" cheating if only the background was wrong. Everything being invisible and in the wrong spot doesn't seem like merely "kind of" cheating. You didn't come anywhere close to addressing the problem that the original post was about.
