For some reason, I need to pass CSS objects using CSS object model inside a react component. Here, I need styles for buttons when they are disabled and when not disabled. Like we do with: backgroundColor, borderRadius and such.
const controlButton = {
backgroundColor:"#006191",
padding:"10px 20px",
border:"none",
borderRadius:"5px"
}
This is where im trying to use it and wanto to pass the object in style.
const App = () => {
const [disable, setDisable] = useState(false);
return(
<div>
<button style={(style.active, disable && style.disable)}>Click</button>
</div>
)
}
Not too elegant but working solution.
import React, { useState } from 'react';
const controlButtonEnabled = {
backgroundColor: '#006191',
padding: '10px 20px',
border: 'none',
borderRadius: '5px',
};
const controlButtonDisabled = {
backgroundColor: 'gray',
padding: '10px 20px',
border: 'none',
borderRadius: '5px',
};
export default function MyAwesomeComponent() {
const [enabled, setEnabled] = useState(true);
const onEnable = () => {
setEnabled(!enabled);
};
return (
<button
onClick={onEnable}
style={enabled ? controlButtonEnabled : controlButtonDisabled}
>
Button
</button>
>
);
}

I have a canvas like this in Component
It can change the pointer to crosshair when cursor is entered on Canvas.
import styles from '../css/basic-styles.module.css';
const ImagePreview = () =>{
[mode,setMode] = useState(0);
changeMode(mode){
setMode(mode);
}
return (){
<canvas className={styles.canvas} width=200 height=200></canvas>
}
}
in css
canvas:hover{
/*cursor:pointer;*/
cursor:crosshair;
}
Now I want to change the css dynamically depending on the mode value.
I want to use pointer when mode is 1
I should quite use css? or is there any method to make it work?
Please see the solution below. It is also available in the sandbox.. Ignore the vanilla react solution it included for the snippet runner. Click Run Code Snippet to see preview here.
/* Solution
const ImagePreview = () => {
const [mode, setMode] = useState(0);
return (
<canvas
onMouseEnter={() => setMode(1)}
onMouseLeave={() => setMode(0)}
style={{
backgroundColor: "teal",
cursor: mode ? "crosshair" : "pointer"
}}
width={200}
height={200}
/>
);
};
*/
// This is so it can work in Stackoverflow snippet preview. //
const ImagePreview = () => {
const [mode, setMode] = React.useState(0);
const canvasCfg = {
onMouseEnter: () => setMode(1),
onMouseLeave: () => setMode(0),
style: { backgroundColor: "teal", cursor: mode ? "crosshair" : "pointer"},
width: 200,
height: 200
}
return React.createElement('canvas', canvasCfg)
}
const domContainer = document.querySelector('#app');
const root = ReactDOM.createRoot(domContainer);
root.render(React.createElement(ImagePreview));
<script crossorigin src="https://unpkg.com/react#18/umd/react.production.min.js"></script>
<script crossorigin src="https://unpkg.com/react-dom#18/umd/react-dom.production.min.js"></script>
<div id="app"></div>
create two classes like this
canvas1:hover{
cursor:pointer;
}
canvas2:hover{
cursor:crosshair;
}
and use it conditionally based on mode like
import styles from '../css/basic-styles.module.css';
const ImagePreview = () =>{
[mode,setMode] = useState(0);
changeMode(mode){
setMode(mode);
}
return (){
<canvas className={mode == 1 ? styles.canvas1 : styles.canvas2} width=200 height=200></canvas>
}
}
you can also use classes without :hover , this will also give the desired result because of cursor property
.canvas1{
cursor: pointer;
}
.canvas2{
cursor: crosshair;
}
Currently, I am trying to modify KeyboardDatePicker board color, size, font, padding, but unfortunately, all approaches don’t work. I tried so far:
1 . useStyles :
const useStyles = (params: any) =>
makeStyles(() =>
createStyles({
componentStyle: {
width: params.width ? params.width : 'auto',
color: params.color ? params.color : 'inherit',
verticalAlign: 'middle',
fontSize: '12px',
border: 'solid 2px #0070D8',
},
})
);
Doesn’t override and a border appears on current KeyboardDatePicker border, size doesn’t change as well.
2 . Theme provide, it overrides calendar theme, but not KeyboardDatePicker date box.
<ThemeProvider theme={theme}>
3 . Add styles into KeyboardDatePicker, it is the only working approach
style={{width:"246px",height:"44px"}}
How would you suggest modifying styles of KeyboardDatePicker, and yes style={} approach it's not the correct way to changes styles. p.s I am using Material-UI 4
My KeyboardDatesPicker:
<KeyboardDatePicker
format="MM/dd/yyyy"
margin="normal"
id="date-picker-inline"
defaultValue={props.value}
value={selectedDate}
required={props.required}
showTodayButton={true}
disableToolbar
inputVariant="outlined"
variant="inline"
onChange={(selectedDate) => setSelectedDate(selectedDate)}
KeyboardButtonProps={{
"aria-label": "change date",
}}
keyboardIcon={<Icon icon={ICONS.Cool_icon} />}
className={classes.componentStyle} // do not overide , but puts on top
/>
makeStyles is a hook factory that returns a style hook (usually called useStyles), this is how it's used:
const useStyles = makeStyles(...);
In your code, you define useStyles as a function that return makeStyles instead of telling makeStyles to create a new hook which doesn't make sense here, so change your code to the above. I also fixed the styles for you. The text color styles should be placed in InputBase component:
const useStyles = makeStyles(() =>
createStyles({
componentStyle: {
verticalAlign: "middle",
fontSize: "12px",
width: (params) => (params.width ? params.width : "auto"),
"& fieldset": {
border: "solid 2px #0070D8"
},
"& .MuiInputBase-root": {
height: (params) => (params.height ? params.height : "auto"),
color: (params) => (params.color ? params.color : "inherit")
}
}
})
);
const classes = useStyles({
color: "red",
width: 400,
height: 80,
});
<KeyboardDatePicker
onChange={() => {}}
inputVariant="outlined"
InputProps={{
className: classes.componentStyle
}}
/>
If you want to style via createMuiTheme, here is the equivalent code. Note that you can't pass the component props to create dynamic styles unlike the useStyles approach above:
const theme = createMuiTheme({
overrides: {
MuiTextField: {
root: {
verticalAlign: "middle",
fontSize: "12px",
width: 150,
"& fieldset": {
border: "solid 2px #0070D8"
}
}
}
}
});
And it should work again. For reference, see this section to know how you can use makeStyles with component props.
It seems you don't need to write a custom hook like this useStyles = (params: any) => ..., the hook returned by makeStyles already accepts a props param.
When styling MUI components you need to check the API for each component to define the object you pass to makeStyles, in this case, the date picker component is a group of other MUI components, if you go to the API you'll see different props to pass to each individual component. To style the input you pass the classes returned by the useStyle hook in InputProps, with root rule as it is in the Input API, apply other rules if you need more specific styles.
const useInputStyles = makeStyles({
root: {
width: (props) => (props.width ? props.width : "auto"),
color: (props) => (props.color ? props.color : "inherit"),
verticalAlign: "middle",
fontSize: "12px",
border: "solid 2px #0070D8"
}
});
...
const inputClasses = useInputStyles()
...
<KeyboardDatePicker
...
InputProps={{ classes: inputClasses }}
/>
and to style the "board", not sure if you mean the popover, since you use the inline variant, you pass the styles in the PopoverProps, defining the styles in the paper rule as described in the Popover API
const usePopoverStyles = makeStyles({
paper: {
backgroundColor: "green"
}
});
...
const popoverClasses = usePopoverStyles();
...
<KeyboardDatePicker
...
PopoverProps={{ classes: popoverClasses }}
/>
you can see it working here https://codesandbox.io/s/mui-keyboarddatepicker-styles-sueqd?file=/src/App.tsx
I have implemented it like this in TS, not a finished component, but I hope that this assists people. I am about to add MuiFormLabel-root etc to add more specific styling to the label.
const useDatePickerStyles = makeStyles<ITheme, ITextFieldStyleProps>((theme) =>
createStyles({
datePickerContainer: ({ isValid, isError }) => ({
border: 'solid',
borderRadius: 4,
borderWidth: theme.mvf.border.width.thin,
borderColor: theme.mvf.palette.border,
...(!isError && {
'&:hover': {
boxShadow: theme.mvf.boxShadow.primary,
borderColor: theme.mvf.palette.primary.main,
},
...(isValid && {
color: theme.mvf.palette.primary.main,
boxShadow: theme.mvf.boxShadow.primary,
borderColor: theme.mvf.palette.primary.main,
}),
}),
...(isError && {
color: theme.mvf.palette.error,
boxShadow: theme.mvf.boxShadow.error,
borderColor: theme.mvf.palette.error,
}),
}),
datePicker: () => ({
margin: theme.mvf.spacing.small,
}),
}),
);
export default useDatePickerStyles;
And get access to classes like so
const DatePicker: DatePickerType = ({
id,
onChange,
format,
value,
label,
errorMessage,
placeholder,
isVerticallyCentered,
...props
}: IDatePickerProps) => {
const isValid = !errorMessage && !!value;
const classes = useDatePickerStyles({
isError: !!errorMessage,
isVerticallyCentered,
isValid,
});
return (
<div className={classes.datePickerContainer}>
<MuiPickersUtilsProvider utils={DateFnsUtils}>
<KeyboardDatePicker
id={id}
fullWidth
maxDateMessage={''}
minDateMessage={''}
invalidDateMessage={''}
className={classes.datePicker}
label={isVerticallyCentered ? undefined : label} // don't show as label will be outside
placeholder={placeholder}
format={format} // of the displayed date
emptyLabel={placeholder} // displayed value if empty
name="datePicker"
InputLabelProps={{
className: classes.inputLabel,
}}
margin="normal"
value={value}
onChange={onChange}
InputProps={{
className: classes.inputPropsClasses,
inputProps: { className: classes.textInput },
disableUnderline: true,
}}
inputVariant="standard"
KeyboardButtonProps={{
className: classes.calendarButton,
}}
{...props}
/>
</MuiPickersUtilsProvider>
</div>
);
};
I am trying to override pseudo-classes in Stepper component using makeStyles:
const useStyles = makeStyles((theme) => ({
active: {
color: theme.palette.primary.main,
},
completed: {
color: theme.palette.goodyear.status.positive,
},
root: {
color: theme.palette.goodyear.grey.medium,
fontWeight: 500,
},
text: {
color: theme.palette.text.titles,
},
iconContainer: {
transform: 'scale(1.667)',
},
label: {
fontSize: '1.2rem',
fontWeight: 500,
},
}));
const StepLabel = (props) => {
const classes = useStyles();
return (
<MaterialStepLabel
classes={{
iconContainer: classes.iconContainer,
label: classes.label,
}}
StepIconProps={{
classes: {
active: classes.active,
completed: classes.completed,
root: classes.root,
text: classes.text,
},
}}
{...props}
/>
);
};
Unfortunately in the browser the results look like that:
The classes that were created by makeStyles are there, but are overridden by default because it's more specific? You can also see that the completed class is also below the root class, which would be strange, since root is the element in general state, and the completed pseudo should override that styles.
What could be the problem here and how should I use that classes correctly?
Below is the definition of the default styles for StepIcon:
export const styles = (theme) => ({
/* Styles applied to the root element. */
root: {
display: 'block',
color: theme.palette.text.disabled,
'&$completed': {
color: theme.palette.primary.main,
},
'&$active': {
color: theme.palette.primary.main,
},
'&$error': {
color: theme.palette.error.main,
},
},
/* Styles applied to the SVG text element. */
text: {
fill: theme.palette.primary.contrastText,
fontSize: theme.typography.caption.fontSize,
fontFamily: theme.typography.fontFamily,
},
/* Pseudo-class applied to the root element if `active={true}`. */
active: {},
/* Pseudo-class applied to the root element if `completed={true}`. */
completed: {},
/* Pseudo-class applied to the root element if `error={true}`. */
error: {},
});
The key to understanding the problems you are experiencing is to better understand how CSS specificity works.
In the styles above, you can see that all the states other than the default are applied via a declaration with two CSS class names. The & refers back to root and then $completed and $active refer to the corresponding rules defined via completed: {} and active: {}. As you saw when inspecting the styles, &$completed resolves eventually to be .MuiStepIcon-root.MuiStepIcon-completed.
The styles in a CSS declaration with two class selectors (e.g. .MuiStepIcon-root.MuiStepIcon-completed) will always win over styles in a CSS declaration with a single class selector (as is the case with all of your styles). When specificity is the same, such as with your makeStyles-root-x and makeStyles-completed-x, then the one declared last will win. You declared your root class after your completed class (and this relative ordering carries through to the stylesheet in the <head> generated for your makeStyles call), so your root class wins.
For your style overrides to work, you should use the same specificity as used in the default styles in Material-UI. I would recommend defining your root and completed styles as follows:
const useStyles = makeStyles((theme) => ({
root: {
color: theme.palette.goodyear.grey.medium,
fontWeight: 500,
"&.MuiStepIcon-completed": {
color: theme.palette.goodyear.status.positive,
},
},
}));
With this approach you don't need to specify anything for completed within the classes prop -- just root.
Below is a full working example based on one of the demos (the stepIconRoot class being the most relevant portion):

I have ReactJS project and I want to change colour of button during clicking. I know that it is a Ripple API but it's very incomprehensible to use it. Could someone advise me how can I do that?
I've tried to create two elements - parent and child - and changed background of child to transparent while clicking. Unfortunately I have also 'classes' object responsible for changing class if button is active and it is just not working.
My code below:
import React, { Component } from 'react';
import { withStyles } from '#material-ui/core/styles';
import Button from '#material-ui/core/Button';
import PropTypes from 'prop-types';
import styles from './MydButton.style';
class MyButton extends Component {
constructor(props) {
super(props);
this.state = {
isClicked: false
};
}
handleClick = () => {
this.setState({ isClicked: !this.state.isClicked });
}
render() {
const {
classes,
children,
color,
disabled,
className,
onClick,
type,
border,
...props
} = this.props;
const myClass = this.state.isClicked ? 'auxClass' : 'buttonDefaultRoot';
return (
<div className={classes.parentRoot} >
<Button
classes={{
root: disabled
? classes.buttonDisabledRoot
: classes.buttonRoot,
label: disabled
? classes.buttonLabelDisabled
: classes.buttonLabel,
}}
{...props}
onClick={this.handleClick}
className={myClass}
disabled={disabled}
type={type === undefined ? 'button' : type}
>
{children}
</Button>
</div>
)
}
};
MyButton.propTypes = {
children: PropTypes.string.isRequired,
disabled: PropTypes.bool,
classes: PropTypes.object.isRequired,
};
MyButton.defaultProps = {
disabled: false,
};
export default withStyles(styles)(MyButton);
and styles:
const buttonRoot = {
border: 0,
height: 48,
width: '100%',
}
export default theme => ({
buttonDefaultRoot: {
...buttonRoot,
transition: 'all 1s ease-in-out',
backgroundImage: 'linear-gradient(to right, #F59C81, #E65DA2, #E65DA2, #B13A97, #881E8E)',
boxShadow: '0px 1px 3px rgba(0, 0, 0, 0.16)',
backgroundSize: '300% 100%',
marginTop: 0,
'&:hover': {
backgroundPosition: '100% 0%',
transition: 'all 1s ease-in-out',
}
},
parentRoot: {
...buttonRoot,
backgroundColor: 'red',
backgroundSize: '300% 100%',
marginTop: 36,
},
auxClass: {
backgroundImage: 'none',
},
Material UI Core for ReactJS
The documentation is very good. I have updated my answer to accomodate the specific needs of this question. I have also included two general solutions for anyone who stumbles upon this question.
Tailored Solution:
Changes background color of button from classes.buttonDefaultRoot (a color defined by owner of question) to the gradient defined by the owner of this question.
First step, have a variable stored in state. You can call it whatever you want, but I'm calling bgButton. Set this to this.props.classes.buttonDefaultRoot like so:
state = {
bgButton: this.props.classes.buttonDefaultRoot,
}
Next, you want to define your function that will handle the click. Again, call it what you want. I will call it handleClick.
handleClick = () => {
const { classes } = this.props; //this grabs your css style theme
this.setState({ bgButton: classes.parentRoot.auxClass }); //accessing styles
};
A couple of things are happening here. First, I am destructuring props. So, I am creating a new const variable called classes that has the same value as this.props.classes. The classes contains a set of objects that defines your css styles for your buttons, margins, etc. You can access those styles just like you would if you were trying to get the value of a prop in an obj.
In this case you can access your button style by doing, classes.buttonDefaultRoot. That takes care of your handle click function.
Last step: render the button. In your render method you want to grab your bgButton from state like so:
render() {
const { bgButton } = this.state;
Then you want to assign your className of your button to bgButton and add the onClick functionality like this (this follows the Material UI Core documentation):
<Button variant="contained" color="primary" className={classNames(bgButton)} onClick={this.handleClick}>Button Name</Button>
Putting it all together you get this:
import React, { Component } from "react";
import Button from "#material-ui/core/Button";
import PropTypes from "prop-types";
import classNames from "classnames";
import { withStyles } from "#material-ui/core/styles";
export default theme => ({ ... }) //not going to copy all of this
class MyButton extends Component {
state = {
bgButton: null
};
handleClick = () => {
const { classes } = this.props;
this.setState({ bgButton: classes.parentRoot.auxClass });
};
render() {
const { bgButton } = this.state;
return (
<div className={classes.container}>
<Button
variant="contained"
color="primary"
className={classNames(bgButton)}
onClick={this.handleClick}
>
Custom CSS
</Button>
</div>
);
}
}
MyButton.propTypes = {
classes: PropTypes.object.isRequired
};
export default withStyles(styles)(MyButton);
General Solution
This solution is for those who want to use the predefined colors, i.e. default, primary, secondary, inherit. This implementation does not need the PropTypes or className imports. This will change the color from the predefined blue to the predefined pink. That's it.
state = {
bgButton: "primary",
}
handleClick = () => {
this.setState({ bgButton: "secondary" });
}
render() {
const { bgButton } = this.state;
return(
...
<Button
onClick = {this.handleClick}
variant = "contained" //checked Material UI documentation
color={bgButton}
> ..etc.
General Solution 2
To accommodate your custom styles to the button, you would have to import PropTypes and classNames and take a similar approach as the tailored solution above. The only difference here will be my syntax and class name. I am closely following the documentation here so you can easily follow along and readjust where necessary.
import React, { Component } from "react";
import Button from "#material-ui/core/Button";
import PropTypes from "prop-types";
import classNames from "classnames";
import { withStyles } from "#material-ui/core/styles";
import purple from "#material-ui/core/colors/purple";
const styles = theme => ({
container: {
display: "flex",
flexWrap: "wrap"
},
margin: {
margin: theme.spacing.unit
},
cssRoot: {
color: theme.palette.getContrastText(purple[500]),
backgroundColor: purple[500],
"&:hover": {
backgroundColor: purple[700]
}
},
bootstrapRoot: {
boxShadow: "none",
textTransform: "none",
fontSize: 16,
padding: "6px 12px",
border: "1px solid",
backgroundColor: "#007bff",
borderColor: "#007bff",
fontFamily: [
"-apple-system",
"BlinkMacSystemFont",
'"Segoe UI"',
"Roboto",
'"Helvetica Neue"',
"Arial",
"sans-serif",
'"Apple Color Emoji"',
'"Segoe UI Emoji"',
'"Segoe UI Symbol"'
].join(","),
"&:hover": {
backgroundColor: "#0069d9",
borderColor: "#0062cc"
},
"&:active": {
boxShadow: "none",
backgroundColor: "#0062cc",
borderColor: "#005cbf"
},
"&:focus": {
boxShadow: "0 0 0 0.2rem rgba(0,123,255,.5)"
}
}
});
class MyButton extends Component {
state = {
bgButton: null
};
handleClick = () => {
const { classes } = this.props;
this.setState({ bgButton: classes.cssRoot });
};
render() {
const { classes } = this.props; //this gives you access to all styles defined above, so in your className prop for your HTML tags you can put classes.container, classes.margin, classes.cssRoot, or classes.bootstrapRoot in this example.
const { bgButton } = this.state;
return (
<div className={classes.container}>
<Button
variant="contained"
color="primary"
className={classNames(bgButton)}
onClick={this.handleClick}
>
Custom CSS
</Button>
</div>
);
}
}
MyButton.propTypes = {
classes: PropTypes.object.isRequired
};
export default withStyles(styles)(MyButton);
A tip. You no longer need a constructor or to bind methods.
Hope this helps.
I want to write and style a functional stateless component in ReactJs as described here.
const MyBlueButton = props => {
const styles = { background: 'blue', color: 'white' };
return <button {...props} style={styles} />;
};
The problem is that I want to add in some styles from stateful components as described here.
const styles = theme => ({
root: {
width: '100%',
maxWidth: 360,
backgroundColor: theme.palette.background.paper,
},
});
The problem is that when I try to do something like this:
<div className={classes.root}>
I get the error:
'classes' is not defined no-undef
How do I access the withStyles classes object to style root the way I want?
If I understood right here is how you can do this with a functional component.
const styles = theme => ( {
root: {
width: "100%",
maxWidth: 360,
backgroundColor: theme.palette.background.paper,
},
} );
const App = ( props ) => {
const { classes } = props;
return <div className={classes.root}>Foo</div>;
};
export default withStyles( styles )( App );
