Create a beautiful Count Down with html, CSS & JavaScript For New year 2021

Create a beautiful particle.js countdown for the new year 2021.
Using CSS styles to decorate the count down screen.



Now create a folder for the code and save this code with .html and then paste this image within the same folder.
