[React] 가상화폐시세 사이트 1 - CSS reset

CSS reset 방법

1. css 직접 적용하기 
2. styled-reset 적용하기
3. createGlobalStyle로 전체 문서에 스타일 적용하기

✅<></>로 리턴할 때, 가상의 묶음을 형성하여 쓸데없이 <div>를 생성하지 않을 수 있음

import { createGlobalStyle } from "styled-components";
import Router from "./Router";

const GlobalStyle = createGlobalStyle`
  body {
    color:red;
  }
`;

function App() {
  return (
    <>
      <GlobalStyle />
      <Router />
    </>
  );
}

export default App;

reset css를 적용한 코드

// App.tsx
import { createGlobalStyle } from "styled-components";
import Router from "./Router";

const GlobalStyle = createGlobalStyle`
