Can I get rid of the first margin, instead of widening the page but having it take room from both margins, just take up all the beginning space, and have a full margin at the end?
If someone could tell me just how to change the page start position, I would love that. Thanks.

You can adjust the following numbers as you want.

JS.setCss ("#gameBorder", "margin-left: 0px")
JS.setCss ("#gameBorder", "width: 1900px")

Daeun, thanks. I really appreciate your help with that.
