I am new to Vue and I had a problem understanding how thinks works in Vue, One of the problems was including my own custom CSS file in a project.
I have created file style.css in src folder and the code in index.html didn't worked for me:
<link rel="stylesheet" type="text/css" href="style.css" />
I had to import styles in main.js file and copied the whole path
'/home/timotej/Desktop/TestProjekt/projekt/src/style.css'
so the whole main.js file looks like this:
import Vue from 'vue'
import App from './App.vue'
import style from '/home/timotej/Desktop/TestProjekt/projekt/src/style.css' // styles ..
Vue.use(style) // styles ..
Vue.config.productionTip = false
new Vue({
render: h => h(App),
}).$mount('#app')
now it should work !

i have installed rellax.js in vue3 project.
import App from './App.vue'
import VueRellax from 'vue-rellax'
createApp(App).use(VueRellax).mount(#app)
but when i add rellax class on any components template tags its not working
<section class="rellax section portfolio-section pd-34" id="portfolio">
<PortfolioComponent />
</section>
not working when i add class rellax in component class even doesnot show in inspect
It looks like vue-rellax was never rewritten for Vue 3. You're likely better off to use the rellax library and import it into your components or as a window variable.
App.vue:
<script setup>
import { onMounted } from 'vue';
import Rellax from 'rellax'
onMounted(() => {
let rellax = new Rellax('.rellax');
})
</script>
I am currently working on a project with Vue 3 and Element Plus.
As of the moment, the element plus Icons are not showing on my app.
I have installed them with yarn using
$ yarn add #element-plus/icons
and I have no idea what to do next.
I have tried importing it on my main.ts file.
import { createApp } from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
import ElementPlus from "element-plus";
import "element-plus/dist/index.css";
import "#element-plus/icons";
createApp(App).use(store).use(router).use(ElementPlus).mount("#app");
But it is not showing still.
The #element-plus/icons package contains named exports for each icon found in the Icon Collection. For example, to use the MagicStick icon, import it by name, and register it as a component. In Vue 3, you can use a <script setup> block to locally register the component simply by importing the component:
<script setup>
import { MagicStick } from '#element-plus/icons-vue'
</script>
Then use it as a component in your template:
within <el-icon>, which lets you easily specify the icon's size and color as props
Note: Clicking an icon card from the Icon Collection UI automatically copies boilerplate markup (<el-icon><magic-stick/><el-icon>) to your clipboard for easily pasting it into your own file.
<template>
<el-icon :size="100">
<MagicStick />
</el-icon>
</template>
or standalone, which requires applying your own styles:
<template>
<MagicStick class="icon" />
</template>
<style scoped>
.icon {
color: #f00;
height: 200px;
}
</style>

I tried importing my App. vue file inside app.js like this:
import Vue from 'vue';
import App from './App';
new Vue({
el: '#app',
render: h => h(App)
});
My App.vue file:
<template>
<div>
<h2>My Application</h2>
</div>
</template>
<script>
export default {
}
</script>
<style>
</style>
This doesnt work an gives me this error:
"export 'default' (imported as 'App') was not found in './App'
However, if I add .vue inside my import it suddenly works just fine. In other tutorials I found for Symfony and vue it works fine without having to add .vue. Any reason as to why it's not working for me?
I'm running into a weird problem. I'm using NextJS for its server-side rendering capabilities and I am using ReactQuill as my rich-text editor. To get around ReactQuill's tie to the DOM, I'm dynamically importing it. However, that presents another problem which is that when I try to access the component where I'm importing ReactQuill via a anchor link is not working but I can access it via manually hit the route. Here is my directories overview,
components/
crud/
BlogCreate.js
pages/
admin/
crud/
blog.js
index.js
blogs/
index.js
In my pages/admin/index.js
...
<li className="list-group-item">
<Link href="/admin/crud/blog">
<a>Create Blog</a>
</Link>
</li>
...
In my pages/admin/crud/blog.js
import BlogCreate from "../../../components/crud/BlogCreate";
...
<div className="col-md-12">
<BlogCreate />
</div>
In my components/crud/BlogCreate.js
import dynamic from "next/dynamic";
const ReactQuill = dynamic(() => import("react-quill"), { ssr: false });
import "../../node_modules/react-quill/dist/quill.snow.css";
...
<div className="form-group">
<ReactQuill
value={body}
placeholder="Write something amazing..."
onChange={handleBody}
/>
</div>
in order to use import "../../node_modules/react-quill/dist/quill.snow.css" in components/crud/BlogCreate.js I use #zeit/next-css and here is my next.config.js
const withCSS = require("#zeit/next-css");
module.exports = withCSS({
publicRuntimeConfig: {
...
}
});
Problem
when I click the Create Blog it should be redirect me http://localhost:3000/admin/crud/blog but it just freeze.
But if I manually hit http://localhost:3000/admin/crud/blog then it go to the desire page and work perfect.
And as soon as I manually load that page then Create Blog works. Now I really don't understand where is the problem? Because it show no error that's why I haven't no term to describe my problem that's why I give all the nasty code and directories which I suspect the reason of this error.
It's hard to give you any solution without seeing the entire project(As you mentioned that it shows no error).
You may remove the #zeit/next-css plugin because Next.js 9.3 is Built-in Sass Support for Global Stylesheets. You can use it for css also.
Create a pages/_app.js file if not already present. Then, import the quill.snow.css file:
import "../../node_modules/react-quill/dist/quill.snow.css";
// This default export is required in a new `pages/_app.js` file.
export default function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
If it gives any error then you can create a directory/file to copy-paste the quill.snow.css code in that file.
pages/
_app.js
styles/
quill_style.css
Then import the file in _app.js like,
import "../styles/styles_quill.css";
// This default export is required in a new `pages/_app.js` file.
export default function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
Eventually you can import your custom gobal css here also.
If although the problem remains then provide your git repository. happy coding ✌️
First: remove your #zeit/next-css setup not needed anymore since next.js version 10.
Second: update nex.js to version 10 you could then use regular import on your modules.
import "../../node_modules/react-quill/dist/quill.snow.css";
By the way, I had the same issue with your Nextjs course. ;)
When I route my app to another component by using react-router-dom, the CSS doesn't change.
This is a minimalistic version of the code to demonstrate
App.js
import React from 'react';
import Home from './Home';
function App() {
return (
<div>
<Home></Home>
</div>
);
}
export default App;
Home.js
import React from 'react';
import './Home.css';
const Home = () => {
return (
<h1>Home</h1>
);
}
export default Home;
Home.css
body {
background-color: blue;
}
Dashboard.js
import React from 'react';
import './Dashboard.css';
import React from 'react';
import './Dashboard.css';
const Dashboard = () => {
return (
<div className='content'>
<h1>Dashboard</h1>
</div>
);
}
export default Dashboard;
Dashboard.css
.content {
display: flex;
align-content: center;
align-items: center;
}
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import Dashboard from './Dashboard';
import * as serviceWorker from './serviceWorker';
import { BrowserRouter as Router, Route } from 'react-router-dom';
ReactDOM.render(
<Router>
<div>
<Route exact path='/' component={App} />
<Route path='/dashboard' component={Dashboard} />
</div>
</Router>, document.getElementById('root'));
// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: ...
serviceWorker.unregister();
When I do /dashboard, it loads the Dashboard component, but it keeps the previous CSS that was loaded from the Home component that resides the App component. The background stays blue. I want that when I route to another component because I changed the URL, it loads whatever CSS that new component has attached to it and gets rid of whatever CSS was before. Is that possible?
Edit: I have made an example in CodeSandbox to illustrate. It's a little different from the code above due to the limitations of the playground, but the functionality is the same.
From what can be seen, importing as a module ends up importing it globally. If we comment the line import Home from "./Home"; the blue background disappears. Just importing the component, imports the whole CSS despite the CSS being imported in a modular way. I'm not sure if I am missing something.
Edit 2:
Here are the different solutions I tried:
CSS Modules, but the body style was still globally loaded.
Styled components don't let me modify the body or html selectors CSS. They require me to create a <div> element and
then have that element span the whole body which I would style
as if it was the body. Which is a workaround I don't want to use because for that I rather use CSS Modules for the whole body spanning .
Inline styling also doesn't let me modify the body or html selectors CSS. I would also need to use a workaround like a body spanning <div> as in Styled components.
The problem
When you import a css like you're doing here
import './Home.css';
you're importing it in a global scope, which means it will not disappear once imported.
The solutions
CSS Modules
What you want is either CSS Modules, which is used like this:
import styles from './Home.css';
<a className={styles.myStyleClass}>Hello</a>
Styled components
or a CSS-in-js framework such as styled components which is used like this:
import styled from 'styled-components';
const MyStyledElement = styled.a`
color: blue;
`;
<MyStyledElement>Hello</MyStyledElement>
Regular objects / inline styling
or just "regular" CSS-in-js like:
const myStyle = {
color: blue;
}
<a style={myStyle}>Hello</a>
There are plenty of options when it comes to styling, these alternatives are popular ones that I encourage you to explore and see which you enjoy.
After doing some more tests I have concluded that as of now it is not possible to change whatever CSS styles have been applied to a <body> or <html> selector in an React SPA when a CSS file is already loaded and one uses React Router to render other components. I still appreciate the answers and the time taken to help me find a solution. They are still valid answers if we are not talking about the <body> or <html> node in an HTML document. From them I learned about other ways to use CSS in React. I modified the original post with the solutions I tried.
What ended working was modifying the DOM styles with JavaScript whithin the component itself.
Home.js
import React from "react";
const Home = () => {
// Modify the DOM Styles with JavaScript
document.body.style.backgroundColor = "blue";
// Or uncomment below to modify the
// document root background color
// which in this case would be <html>
//document.bgColor = "blue";
// Or modify the root tag style of the document instead of the
// <body> (<html> in this case)
//document.documentElement.setAttribute('style', 'background-color: green');
return (
<div>
<h1>Home</h1>
<form action="/dashboard">
<input type="submit" value="Go to Dashboard" />
</form>
</div>
);
};
export default Home;
Here is a working example:
Where my app wasn't loading style sheets and the like. However, I was importing my assets directly into my index.html entry point.
By replacing the links with absolute paths as per this documentation, my problem was resolved.
For me, this meant changing
<head>
<link rel="stylesheet" href="./style.css" ></link>
</head>
to this:
<head>
<link rel="stylesheet" href="/style.css" ></link>
</head>
I'm not sure if the same thing would work for your import statements, but it is worth a shot.
