在 Vuejs 实现全球 css 的最佳途径

Import css in your index.html, but if you're using webpack you can just import your stylesheets in your main js config and all your components will get the css.

As comments below suggested if using webpack adding this to main.js works:

import './assets/css/main.css';

I found the best way is to create a new file in the assets folder, I created as global.css but you can name anything of your choice. Then, import this file global.css file in the main.js.

Note: Using this approach you can also create multiple files if you think the global.css is getting really large then simply import all those files in the main.js.

@\assets\global.css

/* move the buttons to the right */
.buttons-align-right {
justify-content: flex-end;
}

main.js

import Vue from 'vue'
import App from './App.vue'
import router from './routes'


Vue.config.productionTip = false


// Importing the global css file
import "@/assets/global.css"


new Vue({
router,
render: h => h(App)
}).$mount('#app')

You can also do something like this: https://css-tricks.com/how-to-import-a-sass-file-into-every-vue-component-in-an-app/

My folders are mostly structured like this:

 - src
- assets
- _global.scss
- _colors.scss
- _fonts.scss
- _paragraphs
- index.scss // <-- import all other scss files.

This also works with normal css.

In App.vue you can add a style property to declare you CSS file:

<style>
@import './assets/css/global.css';
</style>

There are to two ways, as I know, to achieve this.

Approach 1

Utilize vue.config.js configuration, less config can also be replaced with sass:

module.exports = {
css: {
loaderOptions: {
less: {
additionalData: `@import '@/style/common.less';`
}
}
}
}

Approach 2

In your .vue file, make your style looks like this:

<style lang="less">
@import (reference) "../../style/variables.less";
#app {
background: @bgColor;
}
</style>

Note: the (reference) flag is used to make variables defined in variables.less take effect. If you don't have variables, @import "../../style/variables.less"; is sufficient to do the trick.

For your reference, you can also take a look at this link:

1. create a vue.config.js file in your root directory
2. Create a styles folder inside your src folder and you can create your global style file here for example base.scss
3. to use scss install two dependencies

npm install node-loader sass-loader

4. Inside your vue.config.js paste code from below

module.exports = {
css: {
loaderOptions: {
sass: {
additionalData: `@import "@/styles/base.scss";`
}
}
}
};

1. create a new css file in your assets folder for example : global.css
2. import "global.css" to main.js

    import '@/assets/main.css';
