我正在尝试设置类似的页面,这里有后面运行的动画前面的中心元素: https://vincentgarreau.com/particles.js/#default
我设置了这样的东西,它占据了自己的空间,与其他内容分开,而不是在后面:
我希望我的文字出现在粒子动画前面。你能帮忙吗?我尝试使用&#34; z-index&#34;没有成功:<div style="z-index: -1"></div>
我的完整代码为here,或仅在最重要的位上粘贴。
我将此添加到我的HTML中:
<!-- particles.js container -->
<div id="particles-js"></div>
<!-- particles.js lib - https://github.com/VincentGarreau/particles.js -->
<script src="http://cdn.jsdelivr.net/particles.js/2.0.0/particles.min.js">
</script>
CSS:
body {
background-color: #789;
margin-left: 5px;
margin-right: 5px;
padding-top: 60px;
z-index: 900;
position:relative;

#particles-js {

答案 0 :(得分:2)
答案是ZohirSalak CeNa:
将画布设置为此
position : absolute; width:100%; height:100%; z-index:-1;
我会为初学者澄清:
在HTML中,动画元素为<div id="particles-js"></div>
该元素应该转到后台。注意id = element的值。
在CSS中我简单地补充说:
#particles-js {
position : absolute;
width:100%;
height:100%;
z-index:-1;
}
在#
之后注意与HTML文件(id=
)中的particles-js
匹配的名称。
现在看起来像这样:
