我正在学习React,并且在将React-Particles-J(https://www.npmjs.com/package/react-particles-js)设置为我的网站背景时遇到了一些问题。
如果我仅渲染
class App extends Component {
render() {
return (
<div>
<Particles />
</div>
);
}
}
我有了希望的背景。但是,只要我渲染了其他任何内容(例如h1标签),就不会在 react-particles-js上显示它,也就是说,它会移动react-particles-js并显示为单独显示。
例如,如果我渲染
class App extends Component {
render() {
return (
<div>
<h1>Hello World</h1>
<h1>Hello World</h1>
<h1>Hello World</h1>
<Particles />
</div>
);
}
}
export default App;
发生的事情是,“ Hello World”在屏幕的左上角显示了三次,并且在其下方显示了“粒子”,这意味着“粒子”被解释为与h1在同一层上的另一个元素(好像是另一个h1标签),而不是作为所有元素基础的背景元素-无论它们是h1标签,卡片还是导航或其他任何元素-这就是我想要的!
这是我的Particles.js
import React, { Component } from 'react';
import Particles from 'react-particles-js';
var style = {
width: "100vw",
height: "100vh",
};
class ParticlesBackground extends Component {
render() {
return (
<div style={style}>
<Particles
params={{
"particles": {
"number": {
"value": 90
},
"size": {
"value": 2.5
}
},
"interactivity": {
"events": {
"onhover": {
"enable": true,
"mode": "repulse"
}
}
}
}}/>
</div>
)
}
}
export default ParticlesBackground;
这是我的App.js
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import Nav from './Nav'
import MainArea from './MainArea';
import Particles from './Particles';
import PeopleCard from './PeopleCard'
class App extends Component {
render() {
return (
<div>
<h1>Hello World</h1>
<h1>Hello World</h1>
<h1>Hello World</h1>
<Particles />
</div>
);
}
}
export default App;
这就是我所看到的 enter image description here 如您所见,粒子和标签似乎被解释为互斥的。
(PS,我在html.index中将body标签设置为背景颜色#e74c3c,这是您看到的红色背景)
有关如何解决此问题的任何建议?
答案 0 :(得分:0)
我对粒子使用相同的库,这是我的画布CSS,其工作原理与您想要的一样:
210
它固定元素的位置并将其设置在屏幕的最左上角,两个尺寸均设置为100%。
