Question

在这段代码中，我保存了两个div元素，每个元素都设置在页面的整个长度上（100vh），而不是一个在另一个之上，就好像我想要重叠一样。问题的一部分被解决而不是粒子-js中的“绝对”我把“静态”然后它们彼此不重叠，但动画粒子强加于div上的内容

HTML

<div id="particles-js">
</div>

<div class="content">
<h1>Content</h1>
</div>

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/particles.js/2.0.0/particles.min.js"></script>

CSS

#particles-js {
  position: absolute;
    width: 100%;
    height: 100vh;
    z-index: -1;
  background-color: #222;
  background-repeat: no-repeat;
  background-size: cover;
  background-position: 50% 50%;
}


canvas{
    position: absolute;
    width: 100%;
    height: 500px;
    z-index: -1;
}

.content
{
  position: relative;
    height: 100vh;
    background-color: #F4F7F5;

Answer 2

对于js不好，但对于CSS来说，定位两个对象是错误的，因为它们都不能占用整个空间。我建议你使用绝对值和两个相对值的相对值，而不是使用它们来定位它们：left，right，top，bottom

定位div为100vh
