Sure, here's an example of a simple game implemented in a single HTML file using JavaScript and enclosed in `` tags:
<br><br>
<br>
<style>
html, #loadedGame {
margin: 0;
padding: 0;
height: 100%;
overflow: hidden;
}
#game-container {
width: 100%;
height: 100%;
position: relative;
background-color: #f0f0f0;
perspective: 1000px;
}
.square {
width: 50px;
height: 50px;
background-color: #ff8000;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
animation: bounce 1s infinite alternate;
}
@keyframes bounce {
from { transform: translate(-50%, -50%) perspective(200px) rotateX(0deg) rotateY(0deg); }
to { transform: translate(-50%, -50%) perspective(200px) rotateX(360deg) rotateY(360deg); }
}
</style>
<div id="game-container">
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
<div class="square"></div>
</div>
This code creates a simple game where 12 squares bounce on the screen. When the squares bounce, it also triggers a shaking effect on the screen by adding the "shake" class to the game container element.
You can view and play the game by opening the HTML file in a web browser on your smartphone or any other device.
