EDIT: used grid containers which worked but the particles.js interactivity is gone因此，我试图在网站主体中创建导航和页脚，但 particle.js 不断覆盖这些元素。我试过 z-index 但它没有显示出来。 particle.js 不允许我触摸我的导航栏或页脚。会很感激一些帮助。HTML:

谢谢你帮助我!

最佳答案

使用position: fixed而不是绝对

并将交互式 div 的 z-index 设置为高于 1 的值

最后不要在显示粒子的 div 中保留任何内容..

enter image description here我知道它不太好理解，因为你没有使用 React.js但是您遇到的问题将由此解决。

所以我的<Particle/>组件包含 particles.js 文件和我所有的其他 <div>其他内容从<Navigation />开始至 <FaceRecognition />

如果你能看到我使用了一个类particles对于我的粒子组件。这是它的造型

  position: fixed;
  width: 100%;
  z-index: -1;
}

和我所有的其他<div>有z-index大于 1。这是输出
