Using Styled-components, I have tried several ways to apply global styling & media queries to my React App. I'm here to share my preferred method this far (until I find another better way, of course!).

(For this article, I am using React version 17.0.2, and styled component version 5.3.3) Here it is, in step by step format:

Step 01.

• Install styled components

yarn add styled-components

//or

npm install styled-components

Step 02.

• Inside the src folder: create a file, and call it globalStyle.js
• Here is a screenshot of my folder structure

• Inside globalStyle.js, add these codes:

import { css } from "styled-components";

// Create global color
export const ctaColor = () => {
  return css`
        palevioletred
    `;
};

// Create media queries
export const mobile = (props) => {
  return css`
    @media (min-width: 576px) {
      ${props}
    }
  `;
};

• as you can see, we are simply creating functions that return CSS for us.

Step 03.

• To use these "CSS-functions" in our components: just import it, then apply it to our styling.
• It works just like the usual JavaScript functions.
• Refer to the codes below for some examples:

import styled from "styled-components";
import { mobile, ctaColor } from "../../globalStyle";


const Navbar = styled.div`
  display: flex;
  flex-direction: column;
  align-items: center;
  background: ${ctaColor};
  ${mobile({ flexDirection: "row" })}`

Voila!

That is it, short and simple. I hope it is useful for your project.

Cheers,

Your friend,
