Your job is to design a user interface that displays the lotto

Your job is to design a user interface that displays the lotto balls that are drawn when drawing up to balls from a total of 30 balls. Use 5 image elements to display the ball images from the provided zip file. Use a button to perform the drawing. Use a Lotto class object in the script lotto-class.js to simulate drawing the balls. Use a CSS file to set the fonts, colors, and sizes of the elements on your page. Include a link back to your index page. Only show five balls in HTML. The Lotto class object draws the balls with replacement and sorts them in numeric order before outputting them.

Paper For Above Instructions

Designing a user interface for a Lotto game involves several key components, including HTML, CSS, and JavaScript. This project aims to create a simplistic but functional Lotto drawing interface where users can visualize the drawn balls. By utilizing the Lotto class to simulate ball drawing, we ensure the game adheres to Lotto rules, making it an engaging experience for users.

Requirements Overview

The user interface should meet the following requirements:

  • Display five image elements representing lotto balls.
  • Provide a button to trigger the drawing of balls.
  • Implement a Lotto class to handle ball drawing.
  • Utilize CSS for styling the page.
  • Include a navigation link back to the index page.

HTML Structure

Start with a basic HTML structure, which includes a head and body. The head will link to the CSS file and JavaScript file, while the body contains the component elements.

<!DOCTYPE html>


<html lang="en">


<head>


<meta charset="UTF-8">


<meta name="viewport" content="width=device-width, initial-scale=1.0">


<link rel="stylesheet" href="styles.css">


<script src="lotto-class.js" defer></script>


<title>Lotto Drawing Interface</title>


</head>


<body>


<h1>Lotto Drawing Game</h1>


<div id="lotto-balls">


<img id="ball1" src="lottoballs/ball1.png" alt="Ball 1">


<img id="ball2" src="lottoballs/ball2.png" alt="Ball 2">


<img id="ball3" src="lottoballs/ball3.png" alt="Ball 3">


<img id="ball4" src="lottoballs/ball4.png" alt="Ball 4">


<img id="ball5" src="lottoballs/ball5.png" alt="Ball 5">


</div>


<button id="draw-button">Draw Balls</button>


<a href="index.html">Back to Index</a>


</body>


</html>

JavaScript Implementation

The Lotto class is crucial for managing the logic of drawing balls. The following is a sample implementation:

class Lotto {


constructor(totalBalls) {


this.totalBalls = totalBalls;


this.drawnBalls = [];


}


drawBalls(numToDraw) {


this.drawnBalls = [];


for (let i = 0; i < numToDraw; i++) {


const ballNumber = Math.floor(Math.random() * this.totalBalls) + 1;


this.drawnBalls.push(ballNumber);


}


this.sortBalls();


return this.drawnBalls;


}


sortBalls() {


this.drawnBalls.sort((a, b) => a - b);


}


}


document.getElementById("draw-button").addEventListener("click", function() {


const lotto = new Lotto(30);


const results = lotto.drawBalls(5);


for (let i = 0; i < results.length; i++) {


document.getElementById("ball" + (i + 1)).src = "lottoballs/ball" + results[i] + ".png";


}


});

CSS Styling

When styling the Lotto game interface, a CSS file will ensure that the components are visually appealing and user-friendly. An example CSS might look like this:

body {


font-family: Arial, sans-serif;


background-color: #f4f4f4;


text-align: center;


}


lotto-balls img {


width: 50px;


height: 50px;


margin: 10px;


}


button {


background-color: #4CAF50;


color: white;


padding: 10px 20px;


border: none;


cursor: pointer;


}


button:hover {


background-color: #45a049;


}

Conclusion

The design of the Lotto user interface focuses on simplicity and interaction. The combination of HTML, CSS, and JavaScript enables a functional and visually appealing application. By allowing users to understand and engage with the Lotto drawing process, this UI design provides a fun way to experience Lotto games. With the defined parameters for ball drawing and sensible implementation of the Lotto class, this project meets its requirements effectively, while also presenting opportunities for future expansion such as incorporating user preferences for game customization.
