我制作了一个 particle.js 背景,然后制作了一个容器。在这个容器中,我有两个包含一些数据的表,当我减小屏幕大小时,容器本身会超出 particle.js 背景。 我也附上了我的问题的图片,请看一下。
这是我的一个大学元素,过去两天我一直在尝试解决它,但没有得到任何具体的解决方案。
<div id="particles-js">
<div class="container">
<div class="row">
<div class="col-md-6">
<table class="table">
<thead>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Email</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>Doe</td>
<td>john@example.com</td>
</tr>
<tr>
<td>Mary</td>
<td>Moe</td>
<td>mary@example.com</td>
</tr>
<tr>
<td>July</td>
<td>Dooley</td>
<td>july@example.com</td>
</tr>
</tbody>
</table>
</div>
canvas {
display: block;
vertical-align: bottom;
}
#particles-js {
position: absolute;
width: 100%;
height: 100% !important;
background: #00356B;
}
.container {
margin-top: 20px;
position: absolute;
top: 50%;
right: 50%;
-webkit-transform: translate(50%, -50%);
transform: translate(50%, -50%);
color: #fff;
max-width: 90%;
padding: 2em 3em;
background-color: #131415;
text-shadow: 0px 0px 2px #131415;
font-family: 'Open Sans', sans-serif;
}
我希望容器位于 particle.js 背景内,但它位于背景之外。 Image Of The Problem, I am having Container Going Outside Of The Background
最佳答案
不要把内容放在#particles-js
里面.
将它们与 position:relative
放在一个共同的父级中.
因为particles-js
是绝对定位,如果你想让你的内容显示在粒子上面,你需要给它的容器:position: relative; z-index:1;
还要确保内容本身没有任何背景(background
可以放在公共(public)容器或 #particles-js
元素上):
CSS:
.outer-container {
position: relative;
}
#particles-js {
position: absolute;
height: 100%;
width: 100%;
background-color: #212529; /* could go on .outer-container as well */
}
.outer-container .your-content {
position: relative;
z-index: 1;
background-color: transparent;
}
标记:
<div class="outer-container">
<div id="particles-js"></div>
<div class="your-content">
your contents here
</div>
</div>

particlesJS("particles-js", {

为什么?
因为元素带有 position:absolute
将使用最近定位的祖先 (CPA) 作为引用,其中 “最近定位的祖先” 表示具有 position
的第一个最近的父级static
以外的值(默认)。
如果没有 parent 到 <body>
是“定位”,<body>
将被使用。
对于我们的示例,这意味着:#particles-js
将使用 .outer-container
作为 CPA(width: 100%; height: 100%
表示 CPA 维度的百分比),CPA 将根据其非绝对定位内容(即 <table>
)确定大小。 (因为所有 position:absolute
内容都从文档流中取出,因此其父项的行为就像该内容不存在一样)。
