Hallo, berikut ini saya akan share kode game puzzle yang di buat dari html, css dan javascript. Script kode ini bisa kamu kembangkan sebagai bahan pembelajaran. Nah, tanpa basa basi berikut script kode nya.
Pertama-tama buat dulu file dengan nama index.html atau terserah kamu dan masukkan kode html, css dan javascript berikut ini.
<html><head>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="index.css">
</head><body>
<div id="gradient"></div>
<div id="page">
<div id="Message-Container">
<div id="message">
<h1>Congratulations!</h1>
<p>You are done.</p>
<p id="moves"></p>
<input id="okBtn" type="button" onclick="toggleVisablity('Message-Container')" value="Cool!">
</div>
</div>
<div id="menu">
<div class="custom-select">
<select id="diffSelect">
<option value="10">Easy</option>
<option value="15">Medium</option>
<option value="25">Hard</option>
<option value="38">Extreme</option>
</select>
</div>
<input id="startMazeBtn" type="button" onclick="makeMaze()" value="Start">
</div>
<div id="view">
<div id="mazeContainer">
<canvas id="mazeCanvas" class="border" height="1100" width="1100"></canvas>
</div>
</div>
</div>

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery.touchswipe/1.6.18/jquery.touchSwipe.min.js"></script>
</body></html>Kemudian buat file baru di folder yang sama dengan nama index.css dan masukkan kode css di bawah ini.

}Untuk fungsi dari masing-masing kode diatas tidak dijelaskan disini ya, soalnya kalau dijelaskan bakal panjang banget.
Cara menjalankannya tinggal drag file html tadi ke browser kamu dan tampilan nya akan seperti gambar di bawah ini.
Nah, itu adalah kode atau script game puzle yang dibuat dengan html, css, dan javascript. Semoga bermanfaat dan terimakasih sudah berkunjung.
