Answer 1

If you want to change text color , font-size ... of Tooltip there is a simple way.

You can insert a Tag inside Title of Martial Ui Tooltip for example :

<Tooltip title={<span>YourText</span>}>
   <Button>Grow</Button>
</Tooltip>

then you can style your tag anyhow you want.

check below Example :

Another solution with HtmlTooltip

I Use HtmlTooltip and add arrow: {color: '#f5f5f9',}, for the arrow tooltip style.

And much more to the tooltip style itself.

So I use ValueLabelComponent to control the label and put there a Tooltip from MaterialUI.

Hopes it give another way to edit MaterialUI Tooltip :)

const HtmlTooltip = withStyles((theme) => ({
  tooltip: {
    backgroundColor: 'var(--blue)',
    color: 'white',
    maxWidth: 220,
    fontSize: theme.typography.pxToRem(12),
    border: '1px solid #dadde9',
  },
  arrow: {
    color: '#f5f5f9',
  },
}))(Tooltip);

function ValueLabelComponent({ children, open, value }) {
  return (
    <HtmlTooltip arrow open={open} enterTouchDelay={0} placement="top" title={value}>
      {children}
    </HtmlTooltip>
  );
}

...
...

return (
    <div className={classes.root}>
      <Slider
        value={value}
        onChange={handleChange}
        onChangeCommitted={handleChangeCommitted}
        scale={(x) => convertRangeValueToOriginalValue(x, minMaxObj)}
        valueLabelDisplay="auto"
        valueLabelFormat={(x) => '$' + x}
        ValueLabelComponent={ValueLabelComponent}
        aria-labelledby="range-slider"
      />
    </div>
  );

Answer 3

This answer is out of date. This answer was written in 2016 for the 0.x versions of Material-UI. Please see this answer for an approach that works with versions 3 and 4.

well, you can change the text color and the element background customizing the mui theme.

color - is the text color

rippleBackgroundColor - is the tooltip bbackground

Example: Using IconButton - but you could you the Tooltip directly..

import React from 'react';
import IconButton from 'material-ui/IconButton';
import MuiThemeProvider from 'material-ui/lib/styles/MuiThemeProvider';
import getMuiTheme from 'material-ui/lib/styles/getMuiTheme';

const muiTheme = getMuiTheme({
  tooltip: {
    color: '#f1f1f1',
    rippleBackgroundColor: 'blue'
  },
});

const Example = () => (
  <div>
    <MuiThemeProvider muiTheme={muiTheme}>
        <IconButton iconClassName="muidocs-icon-custom-github" tooltip="test" />
    </MuiThemeProvider>
  </div>
);

You can also pass a style object for the Tooltip (in IconButton it's tooltipStyles) - but these styles will only be applied for the root element.

It's not possible yet to change the label style to make it wrap in multiple lines.

Answer 4

I ran into this issue as well, and want for anyone seeking to simply change the color of their tooltip to see this solution that worked for me:

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';

import Tooltip from '@material-ui/core/Tooltip';
import Button from '@material-ui/core/Button';
import DeleteIcon from '@material-ui/icons/Delete';

const useStyles = makeStyles(theme => ({
  customTooltip: {
    // I used the rgba color for the standard "secondary" color
    backgroundColor: 'rgba(220, 0, 78, 0.8)',
  },
  customArrow: {
    color: 'rgba(220, 0, 78, 0.8)',
  },
});

export default TooltipExample = () => {
  const classes = useStyles();

  return (
    <>
      <Tooltip
        classes={{
          tooltip: classes.customTooltip,
          arrow: classes.customArrow
        }}
        title="Delete"
        arrow
      >
        <Button color="secondary"><DeleteIcon /></Button>
      </Tooltip>
    </>
  );
};

The other popular answer (by André Junges) on this question is for the 0.x versions of Material-UI. Below I've copied in my answer from Material UI's Tooltip - Customization Style which addresses this for v3 and v4.

Below are examples of how to override all tooltips via the theme, or to just customize a single tooltip using withStyles (two different examples). The second approach could also be used to create a custom tooltip component that you could reuse without forcing it to be used globally.

import React from "react";
import ReactDOM from "react-dom";

import {
  createMuiTheme,
  MuiThemeProvider,
  withStyles
} from "@material-ui/core/styles";
import Tooltip from "@material-ui/core/Tooltip";

const defaultTheme = createMuiTheme();
const theme = createMuiTheme({
  overrides: {
    MuiTooltip: {
      tooltip: {
        fontSize: "2em",
        color: "yellow",
        backgroundColor: "red"
      }
    }
  }
});
const BlueOnGreenTooltip = withStyles({
  tooltip: {
    color: "lightblue",
    backgroundColor: "green"
  }
})(Tooltip);

const TextOnlyTooltip = withStyles({
  tooltip: {
    color: "black",
    backgroundColor: "transparent"
  }
})(Tooltip);

function App(props) {
  return (
    <MuiThemeProvider theme={defaultTheme}>
      <div className="App">
        <MuiThemeProvider theme={theme}>
          <Tooltip title="This tooltip is customized via overrides in the theme">
            <div style={{ marginBottom: "20px" }}>
              Hover to see tooltip customized via theme
            </div>
          </Tooltip>
        </MuiThemeProvider>
        <BlueOnGreenTooltip title="This tooltip is customized via withStyles">
          <div style={{ marginBottom: "20px" }}>
            Hover to see blue-on-green tooltip customized via withStyles
          </div>
        </BlueOnGreenTooltip>
        <TextOnlyTooltip title="This tooltip is customized via withStyles">
          <div>Hover to see text-only tooltip customized via withStyles</div>
        </TextOnlyTooltip>
      </div>
    </MuiThemeProvider>
  );
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
