[英]How do i place the particles from particles.js behind my content?
我试图将来自particles.js 的粒子动画放在我的 div 后面。
我已经尝试将所有内容放在 #particles-js div 中,并更改内容和 #particles-js 的 z-index。
这是 HTML 的外观:
<div id="particles-js">
<header>
<h1>Vibe!</h1>
<h2>Outwit your friends</h2>
</header>
<div class="main">
<div class="container">
<p>What should we call you?</p>
<input class="input input-lg"type="text">
<button class="btn btn-lg">Join</button>
<button class="btn btn-lg">Create</button>
</div>
</div>
</div>
我的 CSS 也有很多position: absolute
标签,这可能是原因吗?

#particles-js {
position: fixed;
width: 100%;
height: 100%;
background-color: #ccc;
background-size: cover;
background-position: 50% 50%;

<div id="particles-js"></div>
工作示例: jsfiddle.net/7aLnpkoh
你错过了 z-index: -1;
#particles-js {
position: absolute;
left: 0px;
top: 0px;
z-index: -1;
}
