%h1 Solar System
%hr/
%p
I know this is not the first one on CodePen, but I'm a space and physics lover, and I wanted to create mine :)
%p
Here is a true time scaled solar-system, which means that every objects have a time relative to an Earth year.
You can change the number in second of the
%br/
%code $year-in-second
variable to increase the speed of revolutions. Here 1 year = 30 seconds.
%p.hide
Note the css tricks for the Saturn rings (box-shadow) and reverse animation to compensate the orbit.
