Should i use object or css with react? - css

i'm currently working on a small chat app , using reactJS an materialUI component library.
Material UI use a lot of objet to describe the style of our element (like the "sx" props).
I was wondering if i still should use css or shouhd i put my css into my component as an object (more like a vue component). here is an example with an object :
import React from 'react'
import CameraAltIcon from '#mui/icons-material/CameraAlt'
const AvatarForm = ({setAvatar}) => {
return (
<Box sx={sx}>
<label htmlFor="photo">
<CameraAltIcon />
</label>
<input
type="file" accept="image/*"
id="photo"
onChange={ e => setAvatar(e.target.files[0])}
style={{display: "none"}}
/>
</Box>
)
}
export default AvatarForm
const sx = {
position: "absolute",
top: "50%",
left: "50%",
transform: "translate(-50%, -50%)",
textAlign: "center",
}
Is it a good practice ? and why ?

The official React documentation says that, whilst using inline-styles is supported, using standard css classes in generally better for performance.
Thus, in your situation I would recommend sticking to the official docs.

if you prefer your css inside your js files, there is a new way of using it all together which called styled-components. Its really nice and have cool features.

How can a prop value be used in an Stitches js component?

How to pass a prop value into a Stitchesjs component and use it in the component definition?
This is a common pattern in styled-components. In Stitches, however, I can't seem to find a way. Take this component for example:
const Spacer = styled('div', {
'16': {marginBottom: '$16'},
variants: {
size: {
'20': {marginBottom: '$20'}
}
}
});
Instead of creating 10 variants, I want to pass the amount trough a prop:
<Spacer size={'30px'} />
or even better:
<Spacer size={'$sizes$3'} />
How can I use this value so that the marginBottom matches whatever I give it?
Take a look at https://stitches.dev/docs/utils.
And then you can use like this:
<div css={{ mb: '$40' }} />
I was looking for this answer and tried a few different ways.
The easiest way for me turned out to be locally scoped theme-tokens.
So your styled component would look like this:
const Spacer = styled('div', {
marginBottom: '$$marginSize',
});
And then pass the locally scoped token into the css prop:
<Spacer css={{ $$marginSize: '$sizes$3' }} />
There was a discussion on Stitches Github about the possibility to pass dynamic values as property.
But the goal of stitches is to have the smallest runTime possible, so it was not implemented !
Github PR stitches
When you need to use a JSX variable in stitches that can be any value, one solution would be to use CSS variables;
All stitches elements get the css property, and you can pass new properties through it!
Styled component:
export const Box = styled('div', {
marginTop: 'var(--margin-top)',
backgroundColor: 'red',
width: '200px',
height: '200px',
})
Component:
export function Hero({props = 200 }) {
const variableExample = `${props}px`
return (
<>
<Box css={{ '--margin-top': '10px' }} />
<Box css={{ '--margin-top': '150px' }} />
<Box css={{ '--margin-top': variableExample }} />
</>
)
}
By far the best solution that has worked for me for this very problem. simplifies the code and is better to maintain later!

using material-ui for react in a wordpress plugin: css specificity problems

Im trying to properly use material-ui for react in a wordpress plugin.
Problems arise when using inputs for forms and the styling being overwritten by wordpress own styling in the forms.css file.
Im struggling to find a solution for material-ui writing css that has better specificity than forms.css without having to rewrite the styling(I dont wont my own custom styling for material-ui components: I want to use the default one)
Here is an example(text has been edited for readability(removed selectors that dont matter and styling):
react jsx:
<div id='ad-campaign-edit' style={modalStyle} className={classes.root}>
<form
className={classes.form}
noValidate
autoComplete='off'
>
<TextField
id='ad-campaign-name'
className={classes.textField}
variant='filled'
label='Navn pƄ kampanjen'
/>
<TextField
id='ad-campaign-sub-title-text'
className={classes.textField}
variant='filled'
label='Undertekst'
/>
<TextField
id='ad-campaign-sub-price'
className={classes.textField}
variant='filled'
label='Pris'
/>
<Checkbox
defaultChecked
className={classes.textField}
color='primary'
inputProps={{ 'aria-label': 'secondary checkbox' }}
/>
</form>
</div>
forms.css(WP):
input[type="text"], {
...
}
generated css from material-ui:
.MuiInputBase-input {
...
}
other things to note: the css from material-ui is generated after the styling from wordpress in the dom.
Looking at the rules for css specificity(ref www.specifishity.com) forms.css is (0-1-1) and material-ui is (0-1-0).
My question is: how can I make material-ui take presedence without having to rewrite all the css with something like the makeStyles hook?(Can I add better specificity to material-ui in general?)
edit: Forgot to add html/jsx
edit2: rewrote specificity understanding.
I solved it, it's working but not completely.
This solution can be a starting point.
You need to install this npm
https://www.npmjs.com/package/jss-increase-specificity
Then you have to create a <StyleProvider> like described here
https://material-ui.com/styles/advanced/#jss-plugins
What I did
import { create } from 'jss';
import { StylesProvider, jssPreset } from '#material-ui/core/styles';
import increaseSpecificity from 'jss-increase-specificity';
const jss = create({
plugins: [...jssPreset().plugins, increaseSpecificity({ repeat: 1 })],
});
export default function App() {
return (
<StylesProvider jss={jss}>
...
</StylesProvider>
);
}

How can I imitate the look of the outline and label from Material-UI's outlined textfield?

I'm trying to imitate the outlined textfield from Material-UI but I don't know how to hide the border behind the title text.
In the below image, notice how the "Due Date/Time" is taken from the Material-UI library and the title hides the border behind it but when I tried to imitate it with a custom component I just couldn't hide the border.
Alternatively, Is there a better way to use this outline design instead of just implementing it with CSS?
My current component looks liks this:
<div style={inputContainerStyle}>
<div style={{
...titleStyle,
transform: 'translate(-43px, -11px) scale(0.75)',
fontSize: '17px',
color: 'rgba(0, 0, 0, 0.54)',
position: 'absolute',
}}
>
Color
</div>
<div
className="flex-row"
style={{
border: '1px solid rgba(0, 0, 0, 0.23)',
padding: '18.5px 14px',
borderRadius: '4px',
}}
>
{
availableColors.map(color => <div style={colorCircleStyle(color)} />)
}
</div>
</div>
UPDATE
For many scenarios, my later answer (which avoids using TextField and therefore has no side-effects on FormControl context) may be more appropriate: How can I set an static outlined div similar to Material-UI's outlined textfield?
There is a great deal of flexibility in what you can do with TextField. TextField supports plugging in different types of inputs (e.g. Select, input, custom pickers) via the inputComponent property. You could leverage this to put anything inside its labelled outline by creating a custom component like this OutlinedDiv:
import React from "react";
import TextField from "#material-ui/core/TextField";
const InputComponent = ({ inputRef, ...other }) => <div {...other} />;
const OutlinedDiv = ({ children, label }) => {
return (
<TextField
variant="outlined"
label={label}
multiline
InputLabelProps={{ shrink: true }}
InputProps={{
inputComponent: InputComponent
}}
inputProps={{ children: children }}
/>
);
};
export default OutlinedDiv;
The className passed to the inputComponent takes care of the CSS that makes this all work. You can then use this like in the following:
import React from "react";
import ReactDOM from "react-dom";
import OutlinedDiv from "./OutlinedDiv";
import Avatar from "#material-ui/core/Avatar";
import deepOrange from "#material-ui/core/colors/deepOrange";
import deepPurple from "#material-ui/core/colors/deepPurple";
import red from "#material-ui/core/colors/red";
import green from "#material-ui/core/colors/green";
import blue from "#material-ui/core/colors/blue";
import Grid from "#material-ui/core/Grid";
function App() {
return (
<div className="App">
<OutlinedDiv label="Color Picker">
<Grid container justify="center" alignItems="center">
<Avatar style={{ backgroundColor: deepOrange[500] }} />
<Avatar style={{ backgroundColor: deepPurple[500] }} />
<Avatar style={{ backgroundColor: red[500] }} />
<Avatar style={{ backgroundColor: green[500] }} />
<Avatar style={{ backgroundColor: blue[500] }} />
</Grid>
</OutlinedDiv>
<br />
<br />
<OutlinedDiv label="Custom Outlined Thing">
You can put whatever you want in here.
</OutlinedDiv>
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
No need to write Outlined div component and all. As we can achieve this using FormControl, FormLabel and Formgroup.
If you follow the Outlined div logic your input fields will lose focus.
The below solution is very easy and quick you just need to wrap your code:
<FormControl component="fieldset" className="fieldset">
<FormLabel component="Legend">Title</FormLabel>
<FormGroup row>
{/*Your Input fields e.g TextField or Select e.t.c*/}
</FormGroup>
</FormControl>
Now using useStyles apply some css:
fieldset: {
width: '100%',
marginBottom: 10,
padding: 10,
border: '1px solid #ddd',
borderRadius: 5
}
The outlined textfield was really tricky to implement. When pushing that feature, we had to consider several options, each with their own drawbacks
SVG Element
Easy to build and animate, but tough to scale with the surrounding elements. If we had gone this route, we would have needed to listen for some type of resize event, which would mean either using a window resize event, which is not robust, or using a newer and less supported feature such as a ResizeObserver/MutationObserver. There are polyfills, but that would have increased the bundle size about 2K for a relatively small feature.
The SVG route is likely what will be used in the future. It is also worth noting that this is how Google's Material Components Web solves the problem.
Plain old border with a background on the label
This is by far the simplest approach, but it is also somewhat inflexible. You can see an example of this in Google's new sign-in flow. There they actually set the background color to white. This is probably a fine approach for plenty of users, but of course won't work if your background is a gradient or some similar edge case. That said, there's no need to worry about resize because it's just a border.
Fieldset and legend
This is what we ended up going with, largely because of its flexibility for end users. Fieldset and its legend component are both built-in ways of attaining pretty much this exact functionality. The big drawbacks to this are that styling across browsers is tough, and the properties we'd be animating on are not performant, such as legend width. Additionally, it's always best to use semantic HTML of course, which this is not, which means we need to use aria-hidden to instruct screen readers to ignore the element.
Depending on your goals, any one of these solutions may work best for you. Beware that getting the perfect solution that solves all of these problems may be very tricky!
Just apply the same background color on the color div as the parent's background color, you can do it by background-color: inherit like this:
<div style={inputContainerStyle}>
<div style={{
...titleStyle,
transform: 'translate(-43px, -11px) scale(0.75)',
fontSize: '17px',
color: 'rgba(0, 0, 0, 0.54)',
position: 'absolute',
background-color:'inherit' **(just add this line)**
}}
>
Color
</div>
<div
className="flex-row"
style={{
border: '1px solid rgba(0, 0, 0, 0.23)',
padding: '18.5px 14px',
borderRadius: '4px',
}}
>
{
availableColors.map(color => <div style={colorCircleStyle(color)} />)
}
</div>
</div>

How to use react-jsonschema-form with material-ui?

I am doing a form using react-jsonschema-form, but i really want to customize my application (including the form) with the Material-UI.
I am having trouble to use both together because react-jsonchema-form uses a uiSchema for styling and the Material-UI is set on a prop like this :
SimpleModal.propTypes = {
classes: PropTypes.object.isRequired,
};
<FormControl className={classes.formControl}>
How can i use the Material-UI inside the schema forms?
Now you can start use it with standard react-jsonschema-form library! I searched for a long time and found that now it can already be done.
This PR explain using HOC: https://github.com/mozilla-services/react-jsonschema-form/issues/1222
GitHub: https://github.com/cybertec-postgresql/rjsf-material-ui
Playground with material-ui components: https://cybertec-postgresql.github.io/rjsf-material-ui/
import { withTheme } from 'react-jsonschema-form';
import { Theme as MuiTheme } from 'rjsf-material-ui';
const Form = withTheme(MuiTheme);
If you want use component in material UI i did like this...
import material UI
import TextField from '#material-ui/core/TextField'
declare constant and costum widgets
const MyCustomWidget = props => {
return (
<TextField
type="text"
label="Name1"
value={props.value}
onChange={event => props.onChange(event.target.value)}
margin="normal"
/>
)
}
const widgets = {
TextWidget: MyCustomWidget,
}
and in the return of my component
return (
<div>
{' '}
<Form schema={schema1} widgets={widgets} >
{/* this is for disable the button Submit of Form */}{' '}
</Form>
</div>
It works for me
Weird to see there's no answer.
Quick answer: you cant!
Check out project's FAQ about that, it says:
Q: Will react-jsonschema-form support Material, Ant-Design, Foundation, or [some other specific widget library or frontend style]?
A: Probably not. We use Bootstrap v3 and it works fine for our needs. We would like for react-jsonschema-form to support other frameworks, we just don't want to support them ourselves. Ideally, these frontend styles could be added to react-jsonschema-form with a third-party library.
But! ... :) don't go so fast!
The closest I have come to achieve a Material "look and feel" was to use a Bootstrap Theme, Paper by Bootswatch which is quite nice!
Hope this helps anyone

How to style React Native <CheckBox> component?

Is it possible to style the React Native CheckBox component?
There is no style property listed here: https://facebook.github.io/react-native/docs/checkbox.html
I put an invalid style property on it, and the RN warning message that popped up told me all the valid CSS properties, but none of them did anything beneficial towards styling.
The component looks decent, but I want to change it from that teal color to a brand color.
Is it possible?
These properties are not working but are listed as valid style props for CheckBox:
{
height: 50, // changes the hitspace but not the checkbox itself
width: 50,
borderWidth: 1, // does nothing
backgroundColor: 'red', // makes the area around and inside the checkbox red
borderColor: 'green', // does nothing
borderStyle: 'dotted' // does nothing
}
I don't understand why it even exists if everyone just makes their own checkbox. If I did that, I wouldn't really have any use for because all it gives is
value={this.state.rememberMe}
onValueChange={() => this.toggleRememberMe()}
unless there is something magic it does under the hood. It has a decent onChange animation, but that would be deprecated instantly when I make my own and use something like <TouchableHighlight or Opacity> wrapped around an on/off image or <View>.
I can't find any info on Google except hundreds of custom checkboxes. It's actually really hard to search around them.
You can use https://github.com/react-native-community/react-native-checkbox
Android: you can use tintColors.
import CheckBox from '#react-native-community/checkbox';
.
.
.
<CheckBox
value={option.item.selected}
onValueChange={() => {}}
tintColors={{ true: '#F15927', false: 'black' }}
/>
Transform can be used to change CheckBox size.
<CheckBox
style={{ transform: [{ scaleX: 0.8 }, { scaleY: 0.8 }] }}
/>
checkbox examples
https://github.com/react-native-checkbox/react-native-checkbox
No I couldn't find a way, but wrapping it in a View was one option:
<View style={{
position: 'absolute',
right: 0,
width: 50,
height: 50,
margin: 10,
zIndex: 100,
}}>
<Checkbox
status={i === index ? 'checked' : 'unchecked'}
className=""
/>
</View>
Short answer is you simply can't. React Native uses the native Android Checkbox component, and the only customization you get to do is changing the tint colors, as seen in the react-native-checkbox community project. This prop is undocumented in the official React Native docs.
Additionally, here's the TypeScript definition for this component: AndroidCheckBoxNativeComponent.js. Notice how the only props relayed to the native component are onChange, onValueChange, testID, on, enabled and tintColors.
Yes, you can, i recommend you that use react native elements, and with this library you have 2 options, checkedColor and uncheckedColor, by default in checkedColor is green, but you can change it to what you want, for example, checkedColor={"#fff"} or checkedColor="#fff" try them, it apply for 2 options, good luck!
For IOS use onTintColor and pass the value in string onTintColor={'red'}
<CheckBox
onTintColor={Color.theme}
onCheckColor={Color.theme}
value={isSelected}
onValueChange={setSelection}
style={Style OBJECT}
/>
import CheckBox from '#react-native-community/checkbox';
const Checkbox = (props) => {
// const [isSelected, setSelection] = useState(false);
const [toggleCheckBox, setToggleCheckBox] = useState(false)
return (
<View style={[useTailwind``, styles.container]}>
<View style={styles.checkboxContainer}>
<CheckBox
disabled={false}
value={toggleCheckBox}
tintColors={{true: '#368098'}}
onCheckColor={'#6F763F'}
onValueChange={(newValue) => setToggleCheckBox(newValue)}
/>
<Text style={[useTailwind`font-normal text-base font-sans`, styles.label]}>{props.value}</Text>
</View>
{/* <Text>Is CheckBox selected: {isSelected ? "šŸ‘" : "šŸ‘Ž"}</Text> */}
</View>
);
};
its possible now..
just simply gives tint color of the same color of background
