Hey Coders
Welcome to The CODER VERSE blog. first of all Happy Diwali to everyone who reads this blog post, and thanks to you for being part of the coderverse blog. So let’s start our Diwali fire crackers wishes but not in the text, we are HTML developers so We wish Happy Diwali in pure HTML and CSS Code With Diwali Animation.
