How can I customize the appearance of the arrow in a Material UI tooltip?

Looking to enhance the appearance of a Material UI tooltip arrow with custom styling, but struggling to set the border and background colors.

Here's the current configuration in React:

const useStylesBootstrap = makeStyles(theme => ({
arrow: {
    // color: '#E6E8ED',
    border: '1px solid #E6E8ED',
},
tooltip: {
    backgroundColor: theme.palette.common.white,
    border: '1px solid #E6E8ED',
    color: '#4A4A4A'
},

}));

This is my desired outcome:

The goal is to have a gray border for the triangle and a white background.

In the current setup, adjusting the border setting affects the square around the triangle rather than the triangle itself. In non-Material UI contexts, this issue could be resolved using the pseudo-elements :before and :after. Wondering if there is a way to address this within Material UI's customization options. Any guidance from those experienced with Material UI would be greatly appreciated.

Answer №1

Yes, you are correct. In order to override the &:before pseudoselector, you need to write the code like this. You can also view the code sandbox project by visiting this link

import React from "react";
import Button from "@material-ui/core/Button";
import Tooltip from "@material-ui/core/Tooltip";
import { makeStyles } from "@material-ui/core/styles";

const useStyles = makeStyles(theme => ({
  arrow: {
    "&:before": {
      border: "1px solid #E6E8ED"
    },
    color: theme.palette.common.white
  },
  tooltip: {
    backgroundColor: theme.palette.common.white,
    border: "1px solid #E6E8ED",
    color: "#4A4A4A"
  }
}));

export default function ArrowTooltips() {
  let classes = useStyles();

  return (
    <Tooltip
      title="Add"
      arrow
      classes={{ arrow: classes.arrow, tooltip: classes.tooltip }}
    >
      <Button>Arrow</Button>
    </Tooltip>
  );
}

Check out different tooltip styles. Utilize arrow and &::before to specifically target the arrow and apply custom styles. (please note the double ::)

Customizing Styles with makeStyles

arrow: {
    fontSize: 20,
    color: "#4A4A4A",
    "&::before": {
      backgroundColor: "blue",
      border: "2px solid red"
    }
  }

Incorporating into JSX

<Tooltip classes={{ arrow: classes.arrow }} title="Delete" arrow>
        <IconButton aria-label="delete">
          <DeleteIcon />
        </IconButton>
      </Tooltip>

Check out the MUI customization examples for creating your own tooltip design: https://mui.com/material-ui/react-tooltip/#customization

const LightTooltip = styled(({ className, ...props }: TooltipProps) => (
    <Tooltip {...props} classes={{ popper: className }} />
))(({ theme }) => ({
    [`& .${tooltipClasses.arrow}`]: {
        color: theme.palette.common.white,
        "&::before": {
            backgroundColor: theme.palette.common.white,
            border: "1px solid #999"
          }
      },
    [`& .${tooltipClasses.tooltip}`]: {
        backgroundColor: theme.palette.common.white,
        color: 'rgba(0, 0, 0, 0.87)',
        boxShadow: theme.shadows[1],
        fontSize: 11,
    },
}));

Quick update regarding material ui 5: The use of makestyles has been deprecated.

It's important to note that since the tooltip is in a portal, direct styling is not possible.

const StyledTooltip = styled<typeof Tooltip>(({ className, ...props }) => (
  <Tooltip {...props} classes={{ popper: className }} />
))``;

In the render function, you can leverage sx. By setting popper, you are able to access child props via sx.

<StyledTooltip
        open
        arrow
        sx={{
          '& .MuiTooltip-arrow': {
            background: 'red',
          },
        }}
      />

Here's a neat way to implement custom styling:

import Tooltip from '@material-ui/core/Tooltip'
import { withStyles } from '@material-ui/core/styles'

const StyledTooltip = withStyles(theme => ({
    arrow: {
        '&::before': {
            color: 'white'
        }
    },
    tooltip: {
        backgroundColor: '#f5f5f9',
        boxShadow: theme.shadows[8],
        color: 'rgba(0, 0, 0, 0.87)',
        fontSize: 14,
        maxWidth: 800,
        padding: 0,
    },
    tooltipPlacementTop: {
        margin: '4px 0',
    },
}))(Tooltip)


<StyledTooltip
    title={
        <React.Fragment>
        <Typography color="inherit">Custom Tooltip Content</Typography>
        <em>{"And here's"}</em> <b>{'some'}</b> <u>{'awesome details'}</u>.{' '}
        {"It's pretty cool. Right?"}
        </React.Fragment>
    }
>
    <Button>Hover Me</Button>
</StyledTooltip>

Answer №6

After employing the technique, I found success:

    const CustomTooltip = styled(({ className, ...props }: TooltipProps) => (
      <Tooltip {...props} classes={{ popper: className }} />
    ))(({ theme }) => ({
      [`& .${tooltipClasses.arrow}`]: {
        color: theme.palette.common.white,
        "&::before": {
          backgroundColor: theme.palette.common.white,
          border: "1px solid #dee2e6",
        },
      },
      [`& .${tooltipClasses.tooltip}`]: {
        backgroundColor: theme.palette.common.white,
        color: "#212529",
        fontSize: "1.3rem",
        border: "1px solid #dee2e6",
        padding: "16px",
      },
    }));
    
      
    
<CustomTooltip
      title="View a sneak peek of the Transaction details"
      arrow
      placement="right-start"
>
      <HelpOutlineOutlinedIcon />
 </CustomTooltip>
