react笔记之完成Counter组件

前言

counter.js

import React from 'react';
import classes from './Counter.module.css';

// 计数器的组件
const Counter = (props) => {
    return (
        <div className={classes.Counter}>

            {
                (props.amount && props.amount !== 0) ? (
                    <>
                        <button className={classes.Sub}><span>-</span></button>
                        <span className={classes.count}>{props.amount}</span>
                    </>
                ) : null
            }

            <button className={classes.Add}>
                <span>+</span>
            </button>
        </div>
    );
};

export default Counter;

样式部分

.Counter{
    display: flex;
    align-items: center;
}

.Sub,
.Add{
    display: flex;
    justify-content: center;
    align-items: center;
    border: none;
    background-color: #FCBF49;
    width: 36rem;
    height: 36rem;
    border-radius: 50%;
    font-size: 24px;
    padding: 0;
}

.Sub{
    background-color: white;
    border: 1px solid black;
}

.count{
    font-size: 16px;
    margin: 0 5px;
}
