I hope everyone is well and enjoys learning web design. Last time we make newton's cradle animated design with Html & CSS. If you are new here then go to and Newton's Cradle Animated Design With Html & CSS.
Now we will build a game whose name is "Tower Blocks" using Html and CSS. You have to need to create an HTML and a CSS file. So let's go -
Step 1: Create an HTML file
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Game - Tower Blocks</title>
<meta name="viewport" content="width=device-width,user-scalable=no" />
<link rel="stylesheet" href="./style.css" />
</head>
<body>
<div id="container">
<div id="game"></div>
<div id="score">0</div>
<div id="instructions">
Click (or press the spacebar) to place the block
</div>
<div class="game-over">
<h2>Game Over</h2>
<p>You did great, you're the best.</p>
<p>Click or spacebar to start again</p>
</div>
<div class="game-ready">
<div id="start-button">Start</div>
<div></div>
</div>
</div>
<!-- partial -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r83/three.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/latest/TweenMax.min.js"></script>
<script src="./script.js"></script>
</body>
</html>
Step 2: Create a CSS file to style your design.
style.css
@import url("https://fonts.googleapis.com/css?family=Comfortaa");
html,
body {
margin: 0;
overflow: hidden;
height: 100%;
width: 100%;
position: relative;
font-family: "Comfortaa", cursive;
}
#container {
width: 100%;
height: 100%;
}
#container #score {
position: absolute;
top: 20px;
width: 100%;
text-align: center;
font-size: 10vh;
transition: transform 0.5s ease;
color: #333344;
transform: translatey(-200px) scale(1);
}
#container #game {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
#container .game-over {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 85%;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
}
#container .game-over * {
transition: opacity 0.5s ease, transform 0.5s ease;
opacity: 0;
transform: translatey(-50px);
color: #333344;
}
#container .game-over h2 {
margin: 0;
padding: 0;
font-size: 40px;
}
#container .game-ready {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
display: flex;
flex-direction: column;
align-items: center;
justify-content: space-around;
}
#container .game-ready #start-button {
transition: opacity 0.5s ease, transform 0.5s ease;
opacity: 0;
transform: translatey(-50px);
border: 3px solid #333344;
padding: 10px 20px;
background-color: transparent;
color: #333344;
font-size: 30px;
}
#container #instructions {
position: absolute;
width: 100%;
top: 16vh;
left: 0;
text-align: center;
transition: opacity 0.5s ease, transform 0.5s ease;
opacity: 0;
}
#container #instructions.hide {
opacity: 0 !important;
}
#container.playing #score, #container.resetting #score {
transform: translatey(0px) scale(1);
}
#container.playing #instructions {
opacity: 1;
}
#container.ready .game-ready #start-button {
opacity: 1;
transform: translatey(0);
}
#container.ended #score {
transform: translatey(6vh) scale(1.5);
}
#container.ended .game-over * {
opacity: 1;
transform: translatey(0);
}
#container.ended .game-over p {
transition-delay: 0.3s;
}
Step 3: Create a JS file to create events on your game.
