Design a Tic Tac Toe Game in Tailwind CSS

Last Updated : 07 Mar, 2024

The Tic-tac-toe game is a classic two-player game where players take turns marking spaces in a 3×3 grid with their respective symbols. The objective of the game is to get three of one’s symbols in a row, column, or diagonal. This project aims to implement a simple Tic-tac-toe game using HTML, Tailwind CSS, and JavaScript.

Approach:

Create a folder with the name of the project and two files inside it for HTML and JavaScript.
In the HTML file, use the HTML elements like <div>, <span>, heading etc to create the structure of the website.
Now, include Tailwind CSS using the CDN link and style your web page using its classes.
Implement JavaScript to check for the filled places and announce the winner according to that or output draw in case of a draw.

Example: The below code will explain how you can create a tic-tac-toe game using Tailwind CSS.
