Question

我正在测试Material-UI。我已经使用Bootstrap很长时间了，但是对将一些React项目适应Material-UI感兴趣。我一直试图弄清楚的是如何在Material-UI中创建响应卡。过去，我非常依赖Bootstraps响应式容器，所以我不明白为什么我的卡会随页面扩展而不会因窗口浓缩而收缩...如果我们打算为该脚本编写自定义CSS这个我很酷，只需要指出正确的方向即可。

问题：

Material-UI中的响应卡是不是真的？
还是我们要编写css以使卡响应？
如果是这样，我在哪里可以学到呢？（过去经常依赖于Bootstrap）

在此先感谢您的帮助！

谢谢您的提问

要回答您的问题： 1）不是我所知道的 2）不，您不必编写大量的CSS，但是是，在usestyles中有一些CSS 3）下面我详细解释了您必须在代码中编写的CSS。您正在同时使用内联样式和useStyles，请尝试将所有样式放入usestyle hook API中，并使其具有响应能力。希望这有助于让我知道是否需要更清楚地说明。谢谢

据我所知，您可以使用“ useMediaQuery”挂钩使您的设计具有响应能力。

这里是材料UI Card组件页面中的组件，我只添加了useTheme和useMediaQuery导入，并在classes.root下的useStyle内添加了一个中间断点，这是一个有用的链接在“ useMediaQuery”上 https://material-ui.com/components/use-media-query/#usemediaquery

import { useTheme } from "@material-ui/styles";
import useMediaQuery from "@material-ui/core/useMediaQuery";

const useStyles = makeStyles(theme => ({
  root: {
    maxWidth: 345,
    [theme.breakpoints.down("md")] : {
    maxWidth: 200
    }
  },
  media: {
    height: 140
  }
}));
const Card = () =>  {
  const classes = useStyles();
  const theme = useTheme();

  const matches = useMediaQuery(theme.breakpoints.up("sm"));
  return (

    <Card className={classes.root}>
      <CardActionArea>
        <CardMedia
          className={classes.media}

          title="Contemplative Reptile"
        />
        <CardContent>
          <Typography gutterBottom variant="h5" component="h2">
            Lizard
          </Typography>
          <Typography variant="body2" color="textSecondary" component="p">
            Lizards are a widespread group of squamate reptiles, with over 6,000
            species, ranging across all continents except Antarctica
          </Typography>
        </CardContent>
      </CardActionArea>
      <CardActions>
        <Button size="small" color="primary">
          Share
        </Button>
        <Button size="small" color="primary">
          Learn More
        </Button>
      </CardActions>
    </Card>
  );
}
