Neomorphic Tic Tac Toe Game using HTML and CSS Only

In this blog, we will show you how to create a neomorphic Tic Tac Toe game using only HTML and CSS. Neomorphic design, also known as soft UI, is a trending design style that gives a 3D effect to the elements on the screen, making them appear more interactive and engaging. By the end of this tutorial, you’ll have a fully functional Tic Tac Toe game with a sleek neomorphic design that will take your game experience to the next level. So, let’s get started!

Before we start here are some more games you might like to create using css only –

I would recommend you don’t just copy and paste the code, just look at the code and type by understanding it.
