我正在尝试使用particles.js 作为网站的背景。目前，粒子 div 存在，但粒子未出现。我该如何解决这个问题？

索引.html

<!DOCTYPE html>
<html lang="en">
<head>
    <link rel="stylesheet" href="style.css">
    <meta charset="UTF-8">
    <title>Title</title>
</head>

<body>
    <div id="particles-js"></div>
    <script type="text/javascript" src="./particles.js-master/demo/js/app.js"></script>
    <script type="text/javascript" src="./particles.js-master/particles.js"></script>
</body>
</html>

样式.css

body {
    background: #000;
    margin: 0;
    padding: 0;
    height: 100vh;
}

#particles-js {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

我知道particles-js 的存在是因为改变它的背景颜色会对页面产生影响。

您还需要添加粒子 js 配置才能使其正常工作。您可以从https://vincentgarreau.com/particles.js/创建和下载 json 配置

<script type="text/javascript">
 particlesJS("particles-js",<strong>Your JSON here</strong>);
</script>

例如我的 json 可能看起来像：

 {
 "particles": {
 "number": {
 "value": 80,
 "density": {
 "enable": true,
 "value_area": 800
 }
 },
 "color": {
 "value": "#ffffff"
 },
 "shape": {
 "type": "circle",
 "stroke": {
 "width": 0,
 "color": "#000000"
 },
 "polygon": {
 "nb_sides": 5
 },
 "image": {
 "src": "img/github.svg",
 "width": 100,
 "height": 100
 }
 },
 "opacity": {
 "value": 0.5,
 "random": false,
 "anim": {
 "enable": false,
 "speed": 1,
 "opacity_min": 0.1,
 "sync": false
 }
 },
 "size": {
 "value": 3,
 "random": true,
 "anim": {
 "enable": false,
 "speed": 40,
 "size_min": 0.1,
 "sync": false
 }
 },
 "line_linked": {
 "enable": true,
 "distance": 150,
 "color": "#ffffff",
 "opacity": 0.4,
 "width": 1
 },
 "move": {
 "enable": true,
 "speed": 6,
 "direction": "none",
 "random": false,
 "straight": false,
 "out_mode": "out",
 "bounce": false,
 "attract": {
 "enable": false,
 "rotateX": 600,
 "rotateY": 1200
 }
 }
 },
 "interactivity": {
 "detect_on": "canvas",
 "events": {
 "onhover": {
 "enable": true,
 "mode": "repulse"
 },
 "onclick": {
 "enable": true,
 "mode": "push"
 },
 "resize": true
 },
 "modes": {
 "grab": {
 "distance": 400,
 "line_linked": {
 "opacity": 1
 }
 },
 "bubble": {
 "distance": 400,
 "size": 40,
 "duration": 2,
 "opacity": 8,
 "speed": 3
 },
 "repulse": {
 "distance": 200,
 "duration": 0.4
 },
 "push": {
 "particles_nb": 4
 },
 "remove": {
 "particles_nb": 2
 }
 }
 },
 "retina_detect": true
}

非常感谢您的详细回复。但万一有人再次看到这个问题，问题是我的广告拦截器不允许粒子 javascript。
