我已经设置了我的global.css文件,并在index.js中导入它。
--root {
--main-color: red;
}
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
index.js
import "./global.css";
import App from "./App.svelte";
const app = new App({
target: document.body
});
我的Webpack配置
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
entry: "./src/index.js",
output: {
filename: "bundle.js",
path: path.resolve(__dirname, "dist")
},
module: {
rules: [
{
test: /\.(html|svelte)$/,
exclude: /node_modules/,
use: {
loader: "svelte-loader",
options: {
emitCss: true,
hotReload: true
}
}
},
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
fallback: { loader: "style-loader", options: { sourceMap: true } },
use: [
{ loader: "css-loader", options: { sourceMap: true } },
{
loader: "postcss-loader",
options: {
sourceMap: true,
ident: "postcss",
plugins: loader => [
require("postcss-import")({}),
require("postcss-preset-env")(),
require("cssnano")()
]
}
}
]
})
}
]
},
plugins: [new HtmlWebpackPlugin(), new ExtractTextPlugin("styles.css")]
};
很适合为整个应用程序设置全局CSS。但是我正在尝试在我的Svelte组件中使用--main-color。是否有一种方法将它们注入到所有组件的CSS中?
由于我先导入global.css,因此它应该起作用,因为它首先发出一个带有--root {}的文件,然后是其余组件样式。
