Уважаемые знатоки - подскажите, пожалуйста, почему не работают скрипты на сайте?

Хочу поставить этот скрипт - пример - что уже с ним не делал - не работает.

HTML код - вставлял и в страницу, и в header.php

<div id="container">
<div id="c-container">
<canvas id="c">Sorry.</canvas>
</div>
<div id="c2-container">
<canvas id="c2">Sorry.</canvas>
</div>

</div>

CSS код - то же самое - и в страницу, и в header.php -

<style type="text/css">
@import 'https://fonts.googleapis.com/css?family=Lato:100,100i,300,300i,400,400i,700,700 i,900,900i';

body,
html {
margin: 0;
padding: 0;
font-family: 'Lato', sans-serif;
background-color: black;
overflow: hidden;
}

h1,
h2,
h3,
h4,
h5,
h6,
p,
a,
li {
margin: 0;
padding: 0;
}

#container {
width: 100vw;
height: 100vh;
position: relative;
float: left;
opacity: 0;
}

#c-container,
#c2-container {
width: 100vw;
height: 80vh;
position: absolute;
top: 0;
left: 0;
}

canvas {
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
}
</style>

JS код - то же самое - и в страницу, и в footer.php -
