javascript - 如何用Grid Material UI模仿PaddingTop并从顶部填充空行？

Question

假设我们有网格

const App = () => {
  const useStyles = makeStyles(theme => ({
    root: {
      flexGrow: 1
    },
    paper: {
      padding: theme.spacing(2),
      textAlign: "center",
      color: theme.palette.text.secondary
    }
  }));
  const classes = useStyles();

  return (
    <>
      <Grid container>
        <Grid item xs={8}>
          <Grid container spacing={3}>
            <Grid item xs={12}>
              <Paper className={classes.paper}>xs=12</Paper>
            </Grid>
            <Grid item xs={12} sm={6}>
              <Paper className={classes.paper}>xs=12 sm=6</Paper>
            </Grid>
            <Grid item xs={12} sm={6}>
              <Paper className={classes.paper}>xs=12 sm=6</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
          </Grid>
        </Grid>
        <Grid item xs={4}>
          <Grid item xs={12}>
          </Grid>
        </Grid>
      </Grid>
    </>
  );
};

export default App;

我们如何模仿 PaddingTop 并使用 Grid 从顶部添加空行？

Answer 1

您可以使用顶部Grid容器中的spacing={10}获取空间进行调整。

此外，如果您想显示某些内容，还可以使用 xs={12} 添加新网格。

import React from "react";
import "./styles.css";
import { Grid, makeStyles, Paper } from "@material-ui/core";
export default (App = () => {
  const useStyles = makeStyles(theme => ({
    root: {
      flexGrow: 1
    },
    paper: {
      padding: theme.spacing(2),
      textAlign: "center",
      color: theme.palette.text.secondary
    }
  }));
  const classes = useStyles();

  return (
    <>
      <Grid container spacing={2}>
        <Grid item xs={12}>
          <Paper className={classes.paper}>xs=12</Paper>
        </Grid>
        <Grid item xs={8}>
          <Grid container spacing={3}>
            <Grid item xs={12}>
              <Paper className={classes.paper}>xs=12</Paper>
            </Grid>
            <Grid item xs={12} sm={6}>
              <Paper className={classes.paper}>xs=12 sm=6</Paper>
            </Grid>
            <Grid item xs={12} sm={6}>
              <Paper className={classes.paper}>xs=12 sm=6</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
            <Grid item xs={6} sm={3}>
              <Paper className={classes.paper}>xs=6 sm=3</Paper>
            </Grid>
          </Grid>
        </Grid>
        <Grid item xs={4}>
          <Grid item xs={12} />
        </Grid>
      </Grid>
    </>
  );
});
