How to add !important into my inline CSS property?
If I add it after 2px it just ignore whole style.
import React from "react";
export default class Todo extends React.Component {
render() {
const {text} = this.props;
const cardStyles = {
borderWidth: '2px'
};
return (
<div class="card mb-2 border" style={cardStyles}>
<div class="card-body">
<h5 class="card-title m-0">{text}</h5>
</div>
</div>
)
}
}
Apparently it is not supported https://github.com/facebook/react/issues/1881#issuecomment-262257503
meanwhile you can use a hack doing:
<div ref={element => {
if (element) element.style.setProperty('border', '2px', 'important');
}}
/>
It appears it currently isn't supported based on this GitHub issue https://github.com/facebook/react/issues/1881

I have added a modal to display a login pop-up.
My issue is that the Modal itself seems having padding internally which break my user experience.
As you can see below in the image:
Adding a link as I am not able to attached the image. https://photos.app.goo.gl/iJZRZ28o8dQhmJh4A
[enter link description here][1]
and below the code
import React from "react";
import { Modal } from "react-bootstrap";
import '../../assets/styles/Login.css';
class LoginRegisterModal extends React.Component {
constructor(props, context) {
super(props);
this.state = {show: false};
}
....
render() {
const styleModal = {
marginTop: "15%",
marginLeft: "30%",
padding: 0,
width:770,
height:480,
backgroundColor:"#ffffffff",
borderRadius:21.5,
}
const signUpButton = document.getElementById('signUp');
const signInButton = document.getElementById('signIn');
const container = document.getElementById('container');
signUpButton.addEventListener('click', () => {
container.classList.add('right-panel-active');
});
signInButton.addEventListener('click', () => {
container.classList.remove('right-panel-active');
});
return (
<Modal show={this.state.show} style={styleModal} >
<div class="container" id="container">
<div>
.....
</div>
<div class="overlay-container">
<div class="overlay">
<div class="overlay-panel overlay-left">
<h1>Sign in.</h1>
<p>
Nice to see you again.Login and continue the journey.
</p>
<button class="ghost" id="signIn">Sign In</button>
</div>
<div class="overlay-panel overlay-right">
<h1>Hey, new friend!</h1>
<p>New to the Village? Sign up and start your journey</p>
<button class="ghost" id="signUp">Sign Up</button>
</div>
</div>
</div>
</div>
</Modal>
);
}
}
export default LoginRegisterModal;```
I have tried to remove all my containers and just display a simple text using `<p> test </p>` and I am facing the same issue. The `marginTop` and `marginLeft` defined in the style allowed my to move the Modal from the top left corner.
Any idea why I have some margin inside the modal ?

I am having a modal with button inside. Unfortunatly, it's not properly working. During the build I got an error : TypeError: Cannot read property 'addEventListener' of null
Below is the code:
import React from "react";
import { Modal } from "react-bootstrap";
import '../../assets/styles/Login.css';
class LoginRegisterModal extends React.Component {
constructor(props, context) {
super(props);
this.state = {show: false};
}
componentDidMount(){
const signUpButton = document.getElementById('signUp');
const signInButton = document.getElementById('signIn');
const container = document.getElementById('container');
signUpButton.addEventListener('click', () => {
container.classList.add('right-panel-active');
});
signInButton.addEventListener('click', () => {
container.classList.remove('right-panel-active');
});
}
....
render() {
const styleModal = {
marginTop: "15%",
marginLeft: "30%",
padding: 0,
width:770,
height:480,
backgroundColor:"#ffffffff",
borderRadius:21.5,
}
return (
<Modal show={this.state.show} style={styleModal} >
<div class="container" id="container">
<div>
.....
</div>
<div class="overlay-container">
<div class="overlay">
<div class="overlay-panel overlay-left">
<h1>Sign in.</h1>
<p>
Nice to see you again.Login and continue the journey.
</p>
<button class="ghost" id="signIn">Sign In</button>
</div>
<div class="overlay-panel overlay-right">
<h1>Hey, new friend!</h1>
<p>New to the Village? Sign up and start your journey</p>
<button class="ghost" id="signUp">Sign Up</button>
</div>
</div>
</div>
</div>
</Modal>
);
}
}
export default LoginRegisterModal;
I have tried adding a if condition before the addListener but it's just fixing the error but not working.
Also I have tried to replace by onClick instead but it's not working the code
signUpButton = () => {
container.classList.add('right-panel-active');
}
but container is not known..
Any idea?
Thanks
Your code should be inside component did mount method componentDidMount(). That's because when you look for a element with id "signUp" it doesn't exist yet. I don't encourage you to do what you are doing. A better approach would be <button onClick={myMethod}>
I am rendering modals in React.
My index.html looks like this:
<div id="root"></div>
<div id="modal"></div>
And all my modals are rendered (through a portal) as a child of .modal.
Each modal element has the following form:
<div class="modal-background open">
<!-- children -->
</div>
Where the class can be modal-background open or modal-background closed. The entire component is:
interface OwnProps {
children: React.ReactNode
isOpen: boolean
onExit: () => void
}
export class Modal extends React.Component<OwnProps, any> {
_exit = () => this.props.onExit();
_renderModal = () => (
<div className={`modal-background ${this.props.isOpen ? "open" : "closed"}`} onClick={this._exit}>
{this.props.children}
</div>
);
render() {
if (this.props.isOpen) {
document.body.className += " no-scroll";
} else {
document.body.classList.remove("no-scroll");
}
let elem = document.querySelector("#modal");
if (elem == null) {
console.log("Could not render modal.");
return null;
}
return ReactDOM.createPortal(this._renderModal(), elem);
}
}
And the CSS looks like:
.modal-background {
/* Other styling - this a dark backdrop for a modal child */
background-color: rgba(0,0,0,0.2);
transition: opacity 150ms ease-out;
&.closed {
opacity: 0;
pointer-events: none;
}
&.open {
pointer-events: all;
opacity: 1;
&:hover {
cursor: pointer;
}
}
}
So my modal is used like <Modal><CustomModalElement/></Modal>.
When I load the page, my modal elements briefly flash, indicating that they are not hidden on load (but a split-second afterwards).
I can fix this by adding display: none and display: inherit into the css, but then I miss the nice transitions.
Is there a better way to do this?
Not sure you need to do anything else inside your index.html file except
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
<div id="modal"></div>
And for your Modal.js, you could try something along these lines:
import React from "react";
import ReactDOM from "react-dom";
const Modal = props => {
return ReactDOM.createPortal(
<div className="ui dimmer modals visible active">
<div className="ui standard modal visible active">
<div className="header">Delete Object</div>
<div className="content">
Are you sure you want to delete this?
</div>
<div className="actions">
<button className="ui primary button">Delete</button>
<button className="ui button">Cancel</button>
</div>
</div>
</div>,
document.querySelector("#modal")
);
};
export default Modal;
and then inside your other component where the user will execute the modal:
import React from "react";
import Modal from "../Modal"; // or wherever your Modal is in the file tree
const ObjectDelete = () => {
return (
<div>
ObjectDelete
<Modal />
</div>
);
};
export default ObjectDelete;
Keep in mind that the example of modal I offer here is not a reusable component.
I'm pretty new to Reactjs world and I have wrote component that I would love to make beautiful with CSS :)
I have component consisted of few buttons and boxes which would be displayed after button is clicked.
class Days extends React.Component {
constructor(props) {
super(props);
this.state = { showComponent: "Box1" };
}
toggleDiv = name => {
if (name === "monday") {
this.setState({
showComponent: "Box1"
});
} else if (name === "thursday") {
this.setState({
showComponent: "Box2"
});
}
};
render() {
return (
<div>
<button onClick={() => this.toggleDiv("monday")}>
<div className="botun">Monday</div>
</button>
{this.state.showComponent === "Box1" && <Box1 />}
<button onClick={() => this.toggleDiv("thursday")}>
<div className="botun">Thursday</div>
</button>
{this.state.showComponent === "Box2" && <Box2 />}
</div>
);
}
}
class Box1 extends React.Component {
render() {
return (
<div className="container">
<div className="row">
<div className="col">
<h1>BOx1</h1>
</div>
</div>
</div>
);
}
}
class Box2 extends React.Component {
render() {
return (
<div className="container">
<div className="row">
<div className="col">
<h1>Box2</h1>
</div>
</div>
</div>
);
}
}
After button1 is clicked belonging boxes will be shown under.
So my question is how to put all buttons and boxes into one container and style it like in screenshot?
If I include it in my landingpage.js like this
<div className="container">
<div className="row">
<Days />
</div>
</div>
How can I still make my buttons be in one line?
I am not sure how to approach this with CSS.
What is the best practice when using CSS and CSS frameworks with ReactJS?
I am using global style.css and Boostrap.
You should wrap all your buttons inside a single div, give the container a single class, give it's children a modifier class when they are active and if you want to animate the display of the boxes then you shouldn't unmount them when another button is active opting for making them invisible or something like that because otherwise it's kinda difficult to not have React just pop them into existence.
I use inline style tags. It's really a personal preference situation. As you try new things you'll discover the practice that's best for you and for individual projects. An inline style tag looks like this.<div style={{ display: 'flex', width: '100%', backgroundColor: 'red' }}></div> the benefit to this is you can keep styles defined in the component.
I have a react element that has an inline style like this: (Shortened version)
<div className='progress-bar'
role='progressbar'
style={{width: '30%'}}>
</div>
I want to replace the width with a property from my state, although I'm not quite sure how to do it.
I tried:
<div className='progress-bar'
role='progressbar'
style={{{width: this.state.percentage}}}>
</div>
Is this even possible?
You can do it like this
style={ { width: `${ this.state.percentage }%` } }
Example
yes its possible check below
class App extends React.Component {
constructor(props){
super(props)
this.state = {
width:30; //default
};
}
render(){
//when state changes the width changes
const style = {
width: this.state.width
}
return(
<div>
//when button is clicked the style value of width increases
<button onClick={() => this.setState({width + 1})}></button>
<div className='progress-bar'
role='progressbar'
style={style}>
</div>
</div>
);
}
