html - ParticleJS 虽然在后台运行但不允许点击

Question

我有一个简单的页面，其中我希望在背景中使用粒子 js 动画，并有一个按钮和几个 anchor 供用户单击。但是，当我将粒子 js 添加到作为父级的特定 div 时，我无法单击按钮或 anchor 。我确实尝试将它们的 z-index 更改为更高的数字 (z-index:2000)，但这也没有帮助。

This should resolve your issue :

HTML:

<!-- particles.js container -->
<div id="particles-js">
  <div class="test">AAA</div>
</div>

CSS:

canvas {
  index: 0;
  display: block;
  vertical-align: bottom;
}

.test { 
  index: 50;
  top: 100px;
  position: absolute;
}

#particles-js {
  position: absolute;
  width: 100%;
  height: 100%;
  background-color: #b61924;
  background-image: url("");
  background-repeat: no-repeat;
  background-size: cover;
  background-position: 50% 50%;
}}
