Steps for creating Rock-Paper-Scissors Game
To create a Rock-Paper-Scissors Game using HTML, CSS, and vanilla JavaScript, follow the given steps line by line:
- Create a folder. You can name this folder whatever you want, and inside this folder, create the mentioned files.
- Create an
index.htmlfile. The file name must be index and its extension .html - Create a
style.cssfile. The file name must be style and its extension .css - Create a
script.jsfile. The file name must be script and its extension .js
Once you create these files, paste the given codes into the specified files. If you don’t want to do these then scroll down and download all the source code files of the Rock-Paper-Scissors Game, by clicking on the given download button.
First, paste the following codes into your index.html file.

Second, paste the following codes into your style.css file.

margin: 0;
padding: 0;
box-sizing: border-box;
font-family: "Poppins", sans-serif;
}
body {
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
background: #f6f7fb;
}
::selection {
color: #fff;
background-color: #7d2ae8;
}
.container {
padding: 2rem 7rem;
border-radius: 14px;

box-shadow: 0 5px 10px rgba(0, 0, 0, 0.1);
}
.result_images {

column-gap: 7rem;
}
.container.start .user_result {
transform-origin: left;
animation: userShake 0.7s ease infinite;
}
@keyframes userShake {
50% {
transform: rotate(10deg);
}
}
.container.start .cpu_result {
transform-origin: right;
animation: cpuShake 0.7s ease infinite;
}
@keyframes cpuShake {

transform: rotate(-10deg);
}
}
.result_images img {
width: 100px;
}
.user_result img {
transform: rotate(90deg);
}
.cpu_result img {
transform: rotate(-90deg) rotateY(180deg);
}
.result {
text-align: center;
font-size: 2rem;
color: #7d2ae8;
margin-top: 1.5rem;
}
.option_image img {
width: 50px;
}
.option_images {
display: flex;
align-items: center;
margin-top: 2.5rem;
justify-content: space-between;
}
.container.start .option_images {
pointer-events: none;
}
.option_image {
display: flex;
flex-direction: column;
align-items: center;
opacity: 0.5;
cursor: pointer;
transition: opacity 0.3s ease;
}
.option_image:hover {
opacity: 1;
}
.option_image.active {
opacity: 1;
}
.option_image img {
pointer-events: none;
}
.option_image p {
color: #7d2ae8;
font-size: 1.235rem;
margin-top: 1rem;
pointer-events: none;
}
Third, paste the following codes into your script.js file.
// Get to DOM elements
const gameContainer = document.querySelector(".container"),
userResult = document.querySelector(".user_result img"),
cpuResult = document.querySelector(".cpu_result img"),
result = document.querySelector(".result"),
optionImages = document.querySelectorAll(".option_image");
// Loop through each option image element
optionImages.forEach((image, index) => {
image.addEventListener("click", (e) => {
image.classList.add("active");
userResult.src = cpuResult.src = "images/rock.png";
result.textContent = "Wait...";
// Loop through each option image again
optionImages.forEach((image2, index2) => {
// If the current index doesn't match the clicked index
// Remove the "active" class from the other option images
index !== index2 && image2.classList.remove("active");
});
gameContainer.classList.add("start");
// Set a timeout to delay the result calculation
let time = setTimeout(() => {
gameContainer.classList.remove("start");
// Get the source of the clicked option image
let imageSrc = e.target.querySelector("img").src;
// Set the user image to the clicked option image
userResult.src = imageSrc;
// Generate a random number between 0 and 2
let randomNumber = Math.floor(Math.random() * 3);
// Create an array of CPU image options
let cpuImages = ["images/rock.png", "images/paper.png", "images/scissors.png"];
// Set the CPU image to a random option from the array
cpuResult.src = cpuImages[randomNumber];
// Assign a letter value to the CPU option (R for rock, P for paper, S for scissors)
let cpuValue = ["R", "P", "S"][randomNumber];
// Assign a letter value to the clicked option (based on index)
let userValue = ["R", "P", "S"][index];
// Create an object with all possible outcomes
let outcomes = {
RR: "Draw",
RP: "Cpu",
RS: "User",
PP: "Draw",
PR: "User",
PS: "Cpu",
SS: "Draw",
SR: "Cpu",
SP: "User",
};
// Look up the outcome value based on user and CPU options
let outComeValue = outcomes[userValue + cpuValue];
// Display the result
result.textContent = userValue === cpuValue ? "Match Draw" : `${outComeValue} Won!!`;
}, 2500);
});
});
