问题描述
我在一个新的 React 项目中使用了particles-js 以了解有关其工作原理的更多信息。我已经设置了所有并设法将它显示为背景,同时在页面中间有 React 徽标。当网页在一个小窗口中加载并且粒子被拉伸时,问题就出现了。我想我缺少 CSS 属性或其他东西,但我无法弄清楚。
你知道可能是什么错误吗?
真的谢谢你!

这里有一些照片,看看发生了什么:
更新1: 如果它可能是由于 App.css 中的错误,这里是它的代码:
.App {
text-align: center;
}
.App-logo {
height: 40vmin;
pointer-events: none;
}
@media (prefers-reduced-motion: no-preference) {
.App-logo {
animation: App-logo-spin infinite 20s linear;
}
}
.App-header {
min-height: 100vh;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
font-size: calc(10px + 2vmin);
color: white;
}
.App-link {
color: #61dafb;
}
@keyframes App-logo-spin {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
解决方法
你能去掉homeContainer div吗?然后添加这些 CSS 样式:
#particles-js {
position: absolute;
width: 100%;
height: 100%;
background-color: $FFF;
background-image: url("");
background-repeat: no-repeat;
background-size: cover;
background-position: 50% 50%;
}
canvas {
display: block;
vertical-align: bottom;
}
