CSS universal selector is too aggressive

[red-meadow]

Hi. Thank you for the great work!

This CSS rule seems to be too aggressive and affects other parts of the page:

* {
  padding: 0;
  margin: 0;
  top: 0;
  left: 0;
}

In my case it broke the positioning of the element with position: absolute and right: 0.

I guess you are right (also about the great work) and this could be changed to #main
BTW you may not need it at all, it is just for the nice looking full-page demo.
