This is a submission for Frontend Challenge v24.04.17, CSS Art: Earth Day.
Hey there!
I built a Earth showing it’s transition from being natural to dreadfulness with CSS animations.
This simply highlights the immediate need of protecting the earth before it’s gone.

This was pretty challenging to implement the idea of Earth transition from a natural state(blue & green) to it’s deteriorated and dreadful state(gloomy grey)using pure CSS.
I mustered myself on completing this challenge and finished with what I could.
The takeaway from this was learning about keyframes in CSS and not relying on Javascript to enhance the visual outlook of the prototype.
Thanks for this challenge DEV team!
I hope everybody who participated had learnt something regardless of how you feel about it.
