Coming Soon Page - HTML, CSS, JS, jQuery, Google Fonts

This project taught me the importance of setting your box-sizing. Everything was going fine until I got to the desktop view. That image just did not want to cooperate! But now I feel like I've got a better handle on it.

I know the background image isn't quite right on desktop. Not sure what I'm doing wrong, though. I fiddled with it for a good while.

If you can think of any other ways to improve this, I'd love to hear them. Thanks!
