MUI：在彈性框中對齊和調整影像中心

Question

為什麼我的圖像居中對齊，但不兩端對齊？我很困惑..

<Box
      sx={{
        display: 'flex',
        minHeight: '100vh',
        alignItems: 'center',
        flexGrow: 1,
      }}>
      <Container maxWidth="sm">
        <img src="https://static.vecteezy.com/system/resources/previews/001/200/294/original/house-png.png"
          width={200}
          alt="img"
        />
        <LinearProgress sx={{ mt: 4 }} />
      </Container>
    </Box>

Answer 1

如果您想讓內容居中對齊，則必須使用「justifyContent: 'center'」屬性。另外，「Container」元素存在一些問題，您可以使用 。

檢查這是否是您想要實現的目標

<Box
  sx={{
    display: "flex",
    minHeight: "100vh",
    alignItems: "center",
    justifyContent: "center",
    flexGrow: 1
  }}
>
  <Box>
    <img
      src="https://static.vecteezy.com/system/resources/previews/001/200/294/original/house-png.png"
      width={200}
      alt="img"
    />
    <LinearProgress sx={{ mt: 4 }} />
  </Box>
</Box>

您可以用 Box 包裹 img

<Box
  sx={{
    display: 'flex',
    minHeight: '100vh',
    alignItems: "center",
    flexGrow: 1,
  }}
>
  <Container maxWidth="sm">
    <Box
      sx={{
        display: 'flex',
        justifyContent: "center"
      }}
    >
      <img
        src="https://static.vecteezy.com/system/resources/previews/001/200/294/original/house-png.png"
        width={200}
        alt="img"
      />
    </Box>
    <LinearProgress sx={{ mt: 4 }} />
  </Container>
</Box>
