Import styles css into a react js app

i have a trouble importing .css stylesheet on a react basic app, I have this components:

AvatarHeader.js:

import styles from './AvatarHeader.css';

export default function AvatarHeader({ style, children }) {
  return (
    <div>
      <img style={styles.image} src={Background} alt="background">
        { children }
      </img>

AvatarHeader.css:

.image {
   width: 400
}

AvatarHeader.js & AvatarHeader.css are in the same folder.

package.json:

  {
    "name": "UtWeb",
    "version": "0.1.0",
    "private": true,
    "devDependencies": {
      "css-loader": "^0.25.0",
      "react-scripts": "0.9.0",
      "webpack": "^2.2.1",
      "webpack-dev-server": "^1.9.0"
    },
    "dependencies": {
      "react": "^15.4.2",
      "react-dom": "^15.4.2",
      "react-redux": "^4.3.0",
      "react-router": "^2.0.0",
      "redux": "^3.2.1",
      "react-router-redux": "^4.0.0"
    },
    "scripts": {
      "start": "react-scripts start",
      "build": "react-scripts build",
      "test": "react-scripts test --env=jsdom",
      "eject": "react-scripts eject"
    }
  }

Styles aren’t applied on the component, but it’s works if I rewrite AvatarHeader.js so:

  import styles from './AvatarHeader.css';

  const image = {
    width: 400
  }

  export default function AvatarHeader({ style, children }) {
    return (
      <div>
        <img style={image} src={Background} alt="background">
          { children }
        </img>

I don’t understand how to fix this bug for use the first way to import css file.

Answer

import './AvatarHeader.css';`
<img className='image' />` 

is the correct syntax
