//import "./home.css";


export class Home extends React.Component<{}, {}> {
    render() {
        return (
            <div id="page-top" className="landing-page">

I've stumbled upon this question today also and found that TS now can import css directly with webpack and awesome-typescript-loader exactly like this:

import "./home.css";

But if you like me want to use CSS modules, than you will have to add some more steps:

1. npm install --save-dev typings-for-css-modules-loader
2. Change your css-loader to typings-for-css-modules-loader
3. Change your webpack config to smth like this:

```

module: {
    rules: [
        { test: /\.tsx?$/, include: /ClientApp/, use: 'awesome-typescript-loader?silent=true' },
        { test: /\.css$/, use: isDevBuild ? ['style-loader', "typings-for-css-modules-loader?namedExport&modules"] : ExtractTextPlugin.extract({ use: 'typings-for-css-modules-loader?minimize&namedExport&modules' }) },
        { test: /\.(png|jpg|jpeg|gif|svg)$/, use: 'url-loader?limit=1000' }
    ]
}

This will generate typings for css files and you will be able to use them like

import * as style from './home.css';

You cannot directly import CSS or any other static files into typescript using only the typescript compiler, but you can with the help of some build tools...

For example using webpack , you can set up the css-loader and style-loader to search your source code for require('./whatever.css') and add it to the build before safely compiling your typescript. If you also have webpack generate your HTML then your CSS will be automatically injected as a stylesheet.

If you only need css for a class in your component you could do it like below. I like this solution for when inline css does not work and only small changes are needed.

import * as React from "react";
import { Header } from "./header";

export class Home extends React.Component<{}, {}> {
    render() {
        const css = `
        .landing-page {
            background-color: orange;
        }
        `
        return (
            <div>
                <style>
                    {css}
                </style>
                <div id="page-top" className="landing-page">
                    <Header />
                </div>
            </div>  
        );
    }
}
