  1. Nice job!! Love it

    I was think maybe some scroll zoom will be nice too... But I do not know if with pure CSS it is possible.

    Anyway... Congratulations !!

  2. Wow, this is fantastic. I love how toggling between "Correct" and "Idealized" orbit size gives you some perspective on just how monumental a distance it is to get a probe outside of our solar system

  3. Very Cool, though it isn't Pure Css since there is Javascript Included.

  4. Hey Tyler, you are right but I guess you wouldn’t even notice if I delete it 😀
