CSS 3D animations and moving stars

I'm not quite happy with it, I had to do a lot of hacky things to, end the end, no being able to do what I wanted to do.

I had to turn off the 3D animation for the seconds, it was just too fast to keep a nice transition, with it, the seconds were kind of flickering, it was not nice so seconds are the only one without the effect so I hope it looks decent enough.

I learned a lot of new things, like the 3D perspective and box shadows to make the stars, it looks pretty but I'm sure it could have been better.

Any feedback is welcome but be nice or Im gonna cry.
