Observatory Night Opening

On a night plate, an observatory dome turns its slit toward the sky, the shutter slides open, the telescope tilts up and an accent star brightens as it is found, then it all closes again.

Also known as: observatory animation, telescope animation, night sky animation, isometric observatory.

Customizing this snippet

  • Color: set --hln-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --hln-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • Speed: change the duration on the transition or animation shorthand. Staggered delays are relative, so they keep their rhythm.
  • Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
