【问题描述】：

我想设置两个按钮的样式：使用情感 css 的图像向上和向下，但无法这样做。目前，我通常在函数中设置元素的样式。如何使用情感 css 实现这一目标？ 我关注了https://emotion.sh/docs/introduction，但我无法以正确的方式实现它。

    import up from "../img/up.png";

    function PostButton(props) 
    let style = 
    backgroundRepeat: 'no-repeat',
    background: `url($up)`,
    paddingRight: 24,
    paddingTop: 26,
    paddingLeft: 26,
    paddingBottom: 26.6
    ;
    return (
    <button style=style onClick=() => props.handleClick()>props.background</button>
    );
    

//I have written similar code for PostButton2


function Post(props) 
    return (
    <div>
                    <Up >
                        <PostButton src="../images/up.png" handleClick= . 
     props.incrementScore />
                    </Up>                    >

                    <Down >
                        <PostButton2 src="../images/down.png" 
 handleClickprops.decrementScore />
                    </Down>
                </Col>
            </Row>
        </Container>
    </div>
    );
 

【参考方案1】：

假设 src 属性包含背景图片，我认为您需要更新背景才能使用这样的道具：

background: `url($props.src)`,

【参考方案2】：

使用 src 属性作为图像的路径。

// First way, with css from emotion/react

/** @jsx jsx */
import  jsx, css  from '@emotion/react'

const PostButton = ( background, handleClick, src ) => (
  <button css=css`
    background: $`no-repeat url($src)`;
    padding: 26px 24px 26.6px 26px;
  ` 
  onClick=handleClick>background</button>
)

// Second way, with css from emotion/css

import React from 'react'
import  css  from '@emotion/css'

const PostButton = ( background, handleClick, src ) => (
  <button className=css`
    background: $`no-repeat url($src)`;
    padding: 26px 24px 26.6px 26px;
  ` 
  onClick=handleClick>background</button>
)

// Third way, with css from emotion/css, but pass styles as object

import React from 'react'
import  css  from '@emotion/css'

const PostButton = ( background, handleClick, src ) => (
  <button className=css(
    background: `no-repeat url($src)`,
    padding: '26px 24px 26.6px 26px'
  ) 
  onClick=handleClick>background</button>
)
