Use CSS in REACT

Question

How do i use css in react. Keeps throwing ./src/index.js Module not found: Can't resolve './app.css' in 'c:\Repo\ecom-front\src'. I know i'm doing something wrong so would like some help. ecom-front/src/core/Menu.js

import React from "react";
import {Link, withRouter} from "react-router-dom";
import styles from "./app.css";

const Menu = () => (
 <div>
  <nav class="navbar">
       <span class="navbar-toggle" id="js-navbar-toggle">
           <i class="fas fa-bars"></i>
       </span>
       <a href="#" class="logo">logo</a>
       <ul class="main-nav" id="js-menu">
           <li>
               <a href="#" class="nav-links">Home</a>
           </li>
           <li>
               <a href="#" class="nav-links">Products</a>
           </li>
           <li>
               <a href="#" class="nav-links">About Us</a>
           </li>
           <li>
               <a href="#" class="nav-links">Contact Us</a>
           </li>
           <li>
               <a href="#" class="nav-links">Blog</a>
           </li>
       </ul>
   </nav>
  </div>
);

export default withRouter(Menu);

import React from 'react';
import ReactDOM from 'react-dom';
import Routes from './Routes';
import './app.css';

            box-sizing: border-box;
            padding: 0;
            margin: 0;
        }

        body {
            font-family: 'Josefin Sans', sans-serif;
        }

        .navbar {
            font-size: 18px;
            background-image: linear-gradient(260deg, #2376ae 0%, #c16ecf 100%);
            border: 1px solid rgba(0, 0, 0, 0.2);
            padding-bottom: 10px;
        }

        .main-nav {
            list-style-type: none;
            display: none;
        }

        .nav-links,
        .logo {
            text-decoration: none;
            color: rgba(255, 255, 255, 0.7);
        }

        .main-nav li {
            text-align: center;
            margin: 15px auto;
        }

        .logo {
            display: inline-block;
            font-size: 22px;
            margin-top: 10px;
            margin-left: 20px;
        }

        .navbar-toggle {
            position: absolute;
            top: 10px;
            right: 20px;
            cursor: pointer;
            color: rgba(255, 255, 255, 0.8);
            font-size: 24px;
        }

        .active {
            display: block;
        }

        @media screen and (min-width: 768px) {
            .navbar {
                display: flex;
                justify-content: space-between;
                padding-bottom: 0;
                height: 70px;
                align-items: center;
            }

            .main-nav {
                display: flex;
                margin-right: 30px;
                flex-direction: row;
                justify-content: flex-end;
            }

            .main-nav li {
                margin: 0;
            }

            .nav-links {
                margin-left: 40px;
            }

            .logo {
                margin-top: 0;
            }

            .navbar-toggle {
                display: none;
            }

            .logo:hover,
            .nav-links:hover {
                color: rgba(255, 255, 255, 1);
            }
        }

So i tried a lot of different ways to put an external css file, as i am trying to use flexbox or not be dependant on bootstrap. I do not know if i should install an npm package or if i am missing something as i only know the traditional way to implement css just not with REACT.

Can you share your folder structure?

You are importing the css file incorrectly.

Instead of

import styles from "./app.css";

Do this

import "./app.css";

There is no styles being exported from css file. And use className at place of class

<div className="class">Get work done in over 1450 different categories</div>

EDIT: It's because the path you are importing the css from in your ecom-front/src/index.js is wrong

It should be

import './core/app.css';

You need not link it in the section.

Also, use 'className' (case-sensitive) in place of 'class' and if you want to apply class 'some_class' use the syntax

className={ styles.some_class }
