What are some creative ways to customize the background of a MaterialUI modal design?

I am currently facing an issue with my MUI Modal setup. The backdrop is displaying as black even though I have proper styling in place. No matter what I do, the backdrop remains pitch black and does not update.

Below is the code snippet along with a screenshot showing the problem. Any suggestions on how to resolve this would be greatly appreciated!

import { Box, Modal, Typography } from "@material-ui/core";
import React from "react";
import { makeStyles } from "@material-ui/core/styles";

const useStyles = makeStyles((theme) => ({
  modalStyle: {
    position: "absolute",
    top: "50%",
    left: "50%",
    transform: "translate(-50%, -50%)",
    width: 300,
    bgcolor: "background.paper",

    boxShadow: 24,
    p: 4,
    backgroundColor: "white",
    borderRadius: "10px",
  },
}));

const PopupModal = ({ postModalOpen, handleClose, children }) => {
  const classes = useStyles();

  return (
    <Modal open={postModalOpen} onClose={handleClose}>
      <Box className={classes.modalStyle}>
        ModalText
        <Typography
          id="modal-modal-title"
          variant="h6"
          component="h2"
          style={{
            fontSize: "14px",
            marginLeft: "5px",
          }}
        >
          {children}
        </Typography>
      </Box>
    </Modal>
  );
};

export default PopupModal;

Answer №1

Utilizing the slots and slotProps within modal properties can enhance customization.

Here's an example:

<Modal
  open={isOpened}
  onClose={() => setIsOpened(false)}
  closeAfterTransition
  slots={{ backdrop: Backdrop }}
  slotProps={{
    backdrop: {
      sx: {
        //Add your styles here....
        backgroundColor: 'rgba(69, 89, 167, 0.4)',
      },
    },
  }}
>
//Insert your content here...
</Modal>

I trust this will be beneficial.

Here's a personalized touch I added to my MUI Backdrop (MUI version 5)

<Backdrop open={isVisible} sx={{ backgroundColor: 'rgba(0, 0, 0, 0.25)', zIndex: 1 }} onClick={closeOverlay} />

Answer №3

If you want to customize the backdrop, your styles should be applied directly to the Modal component:

For instance:

const customStyles = makeStyles((theme) => ({
  /** Adjusted modalStyle */
  modalStyle: { backgroundColor: "rgba(255, 0, 0, 0.5)" },
  /** Moved content styling to a new class */
  contentStyle: {
    position: "absolute",
    top: "50%",
    left: "50%",
    transform: "translate(-50%, -50%)",
    width: "300px",
    backgroundColor: "white",
    borderRadius: "10px"
  }
}));

const CustomModal = ({ isOpen, closeHandler, children }) => {
  const classes = customStyles();

  return (
    // Modify className props with the provided code
    <Modal
      open={isOpen}
      onClose={closeHandler}
      className={classes.modalStyle}
    >
      <Box className={classes.contentStyle}>
        <Typography
          id="modal-modal-title"
          variant="h6"
          component="h2"
          style={{
            fontSize: "14px",
            marginLeft: "5px"
          }}
        >
          {children}
        </Typography>
      </Box>
    </Modal>
  );
};

Tip: You can also customize all backdrops across your application by providing a global override object for MuiBackdrop in createMuiTheme().

Answer №4

One approach that proved effective for me is to utilize the Modal component's sx property in order to style the css class used by materialUI.

    <Modal
        open={props.open}
        onClose={props.onClose}
        aria-labelledby="modal-modal-title"
        aria-describedby="modal-modal-description"
        sx={{
            '& .MuiModal-backdrop': {
                backgroundColor: 'rgba(0, 150, 150, 0.5);',
            },
        }}
    >
        <Card className='modal'>
            {props.children}
        </Card>
    </Modal>

While a simple hex value can be used to define the color (e.g., backgroundColor: '#00ADB5'), doing so will eliminate the transparency of the backdrop. To retain opacity, it is advisable to employ the rgba() function which enables setting the opacity in the 4th argument (as demonstrated above with a value of 0.5).

This may not be the most elegant solution, but it served as the simplest and functional option for me. Hopefully this proves beneficial to you as well.

<Modal
  open={openModalButtons}
  onClose={() => {
    setOpenModalButtons(false);
  }}
  aria-labelledby="modal-menu-sidebar"
  closeAfterTransition
  BackdropProps={{
    sx: {
      //Custom styles go here....
      background: 'transparent',
    },
  }}
>
  <Fade in={openModalButtons}>
    <Box sx={style}>
      <div>example</div>
    </Box>
  </Fade>
</Modal>
