`;

const CandyItem = styled.li`

margin: 5px 0;

cursor: pointer;

`;

function App() {

const [selectedCandy, setSelectedCandy] = useState(null);

const handleCandyClick = (candy) => {

setSelectedCandy(candy);

};

return (

<AppContainer>

<h1>Halloween Candy Counter</h1>

<CandyList>

{candies.map(candy => (

<CandyItem key={candy.name} onClick={() => handleCandyClick(candy)}>

{candy.name}

</CandyItem>

))}

</CandyList>

{selectedCandy && <CandyDetails candy={selectedCandy} onClose={() => setSelectedCandy(null)} />}

</AppContainer>

);

}

export default App;

import React from 'react';

import styled from 'styled-components';

const DetailsContainer = styled.div`

border: 2px solid white;

padding: 20px;

margin-top: 20px;

width: 300px;

position: relative;

`;

const CloseButton = styled.button`

function CandyDetails({ candy, onClose }) {

return (

<DetailsContainer>

<CloseButton onClick={onClose}>X</CloseButton>

<CandyImage src={candy.img} alt={candy.name} />

<h2>{candy.name}</h2>

<p>{candy.funFact}</p>

</DetailsContainer>

);

}

export default CandyDetails;
