Here’s the HTML code of the coin flip using HTML CSS and JavaScript you’ll be working with:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Heads or Tails</title>
    <script src="https://cdn.tailwindcss.com"></script>

        .coin {

        }
    </style>
</head>

    <div class="flex flex-row min-h-screen justify-center items-center">
    <div class="text-center content-evenly">

Explanation of the HTML Code

DOCTYPE and Meta Tags: The <!DOCTYPE html> declares the document type and the <meta charset="UTF-8"> tag sets the character encoding, ensuring that your page displays text correctly. The <meta name="viewport" tag ensures the page scales correctly on different devices.
Title: The <title> element sets the page title to “Heads or Tails,” which will appear in the browser tab.
Tailwind CSS: The script <script src="https://cdn.tailwindcss.com"></script> includes Tailwind CSS, a utility-first CSS framework that helps in quickly styling the page.
Custom Styles: The <style> block defines custom styles using Tailwind’s @apply directive to apply a gradient background and center the content.
Body Structure: The <body> contains a div that centers the content both vertically and horizontally using Flexbox. Inside, there is a header, a description, counters for heads and tails, and the coin element itself.

Styling the Coin with CSS

Now, we will style our coin flip using HTML CSS and JavaScript. CSS is used to give our application its visual appeal. Here, we’re utilizing Tailwind CSS to simplify the process, but you could easily modify or replace the styles with custom CSS.

body {
    @apply bg-gradient-to-b from-white to-gray-100 flex items-center justify-center min-h-screen;
}
.coin {
    transition: transform 0.6s ease, background-color 0.3s ease;
    cursor: pointer;
}

Explanation of the CSS Code

Body Styles: The body of the page has a gradient background (bg-gradient-to-b from-white to-gray-100) and uses Flexbox to center all content both horizontally and vertically.
Coin Styles: The coin element is given a smooth transition effect for both its transformation and background color changes, making the flipping action more visually appealing.

Adding Interactivity with JavaScript

Now, we are going to add some interactivity in our coin flip using HTML CSS and JavaScript. JavaScript is where the magic happens, bringing the coin to life with a simple flip action and sound effect.

let headsCount = 0;
let tailsCount = 0;
const flipSound = document.getElementById('flipSound');

function flipCoin() {
    const coin = document.getElementById('coin');
    const result = Math.random() < 0.5 ? 'HEADS' : 'TAILS';
    flipSound.play();
    coin.style.transform = 'rotateY(180deg)';
    setTimeout(() => {
        coin.textContent = result;
        coin.style.transform = 'rotateY(0deg)';
        if (result === 'HEADS') {
            coin.style.backgroundColor = '#ec4899'; // Pink for Heads
            headsCount++;
            document.getElementById('headsCount').textContent = headsCount;
        } else {
            coin.style.backgroundColor = '#3b82f6'; // Blue for Tails
            tailsCount++;
            document.getElementById('tailsCount').textContent = tailsCount;
        }
    }, 300);
}

document.getElementById('coin').addEventListener('click', flipCoin);
document.body.onkeyup = function(e) {
    if (e.keyCode == 32) {
        flipCoin();
    }
}

Explanation of the JavaScript Code

Variables: headsCount and tailsCount keep track of how many times each result has occurred.
Coin Flip Function: The flipCoin() function handles the flipping logic. It randomly determines the result of the coin flip using Math.random(), changes the coin’s text and color, and updates the respective counter.
Event Listeners: The event listeners detect either a mouse click on the coin or a press of the spacebar, triggering the flip.

Enhancing User Experience with Sound

Adding sound effects can make the coin flip experience more engaging. In our example, we included an audio element that plays a coin flip sound whenever the coin is flipped.

<audio id="flipSound">
    <source src="Coin Flip Sound Effect.mp3" type="audio/mpeg">
</audio>
