Build Your Own Simple Tetris Game with HTML, CSS, and JavaScript

This tutorial will guide you through creating a basic Tetris game using HTML, CSS, and JavaScript. You'll learn how to set up the game grid, create shapes, implement game logic, and add features like a point system and a reset button.

Instructions:

1. Create an HTML Document: Open your text editor and create a new HTML document.

2. Add the Game Container: Add the following HTML structure to your document:

<div>
  <div class='tetris-container'></div>

7. Complete Row Detection and Removal: Create a function to identify and remove completed rows from the grid.

8. Add Scoring and Game Over Logic: Introduce a scoring system and implement logic to determine when the game is over (e.g., when shapes stack up above the top of the grid).
