Reactデザインパターン〜レイアウトコンポーネント〜

import { SplitScreen } from "./components/split-screen";

const LeftSide = ({ title }) => {
  return <h2 style={{ backgroundColor: "red" }}>{title}</h2>;
};

const RightSide = ({ title }) => {
  return <h2 style={{ backgroundColor: "blue" }}>{title}</h2>;
};

function App() {
  return (
    <SplitScreen leftWidth={1} rightWidth={3}>
      <LeftSide title={"Left"} />
      <RightSide title={"Right"} />
    </SplitScreen>
  );
}

export default App;

import React from "react";
import { styled } from "styled-components";

const Container = styled.div`
  display: flex;
`;

const Panel = styled.div`
  flex: ${(p) => p.flex};
`;
export const SplitScreen = ({ children, leftWidth = 1, rightWidth = 1 }) => {
  const [left, right] = children;
  return (
    <Container>
      <Panel flex={leftWidth}>{left}</Panel>
      <Panel flex={rightWidth}>{right}</Panel>
