In React, how to prevent a component's CSS import from applying to the entire app?

I'm using facebook's create-react app for my application:

In my Login.js container, I am importing CSS like so:

import React from 'react';
import '../../styles/users/Login.css'
const Login = () => {
....

The problem is the Login.css styles are being applied to my entire application... for example, if Login.css has:

body {
    background:Red ;
}

The entire app would have a body of background: Red; Even outside of the Login container.

What I expected/want is for a CSS import within a container to only apply to that particular container.

Is that possible w React? How are react developers supposed to handle container specific stylings? Do I need to add an ID to all containers and include that in the entire CSS file?

The best and easiest solution is to give classNames to every element you have in your code. I had the same issue when trying to apply widths and heights to my images and eventually found out that it was affecting whole app.
