I have a reusable component that contains an animation called AnimationLoader. This component is a reusable component for loading states. I'm simply trying to take this component and use it inside of another component, UnpublishBlogBtn as the loader after a button click - that all works fine. However, I'd like to change the height and width of the animation inside of UnpublishBlogBtn and cannot for the life of me get that to work properly.
I've tried implementing Object.assign to bring in the CSS from the other file and just change the height and width. I've also tried just changing the CSS by doing <style={{}}> as well as wrapping the component in a div that has a style added(this appears to just change the button and not the animation itself).
<Button type="main" className="blogBtn">
{currentlyUnpublishingBlog ? <AnimatedLoader css={{ height: 1, width: 1 }}/> :
'Unpublish Blog'}
</Button>
const AnimatedLoader = () => {
return (
<div
css={{
height: 45,
width: 45
}}
>
<AnimatedIcon
css={{
animationDelay: '0.7s',
height: 35,
left: 10,
position: 'absolute',
top: 10,
width: 35
}}
/>
<AnimatedIcon
css={{
animationDelay: '0.7s'
display: 'none',
height: 45,
left: 0,
top: 0,
width: 45,
}}
/>
<div
css={{
borderRadius: 20,
borderStyle: 'solid',
borderWidth: 3,
height: 45,
position: 'absolute',
width: 45,
}}
/>
</div>
)
};
export default AnimatedLoader;
After user clicks on Unpublish Blog button, the loader should display as a smaller width and height on top of the button. Currently, it maintains the same size as what is listed inside of AnimatedLoader component and I'd like the size to change inside of the UnpublishBlogBtn component.
You can pass your css in as a prop to your AnimatedLoader
const AnimatedLoader = ({css={
height: 45,
width: 45
}}) => {
return (
<div
{...css}
>
<AnimatedIcon
css={{
animationDelay: '0.7s',
height: 35,
left: 10,
position: 'absolute',
top: 10,
width: 35
}}
// ....
If you need to do more complex things, it's probably more sensible to pass in a prop that describes the different style options as a group. So isSmallSize as a boolean or different sizes as an enum etc.
Then in your component you adjust the styles depending on the prop.
const AnimatedLoader = ({ isSmallSize = false }) => {
const outerSize = isSmallSize ?
{ height: 45, width: 45 } : { height: 1, width: 1 }
const iconSize = isSmallSize ?
{ height: 35, width: 35 } : { height: 1, width: 1 }
return (
<div css={{ ...outerSize }}>
<AnimatedIcon
css={{
animationDelay: '0.7s',
left: 10,
position: 'absolute',
top: 10,
...iconSize
}}
/>
<AnimatedIcon
css={{
animationDelay: '0.7s',
display: 'none',
left: 0,
top: 0,
...iconSize
}}
/>
<div
css={{
borderRadius: 20,
borderStyle: 'solid',
borderWidth: 3,
position: 'absolute',
...iconSize
}}
/>
</div>
)
}

I need to build horizontal progress bar with circle at the end in react js, as shown in picture. I am able to build progress bar with custom "%", now I want to add circle at the end with some text inside.
code for progress bar with custom "%":
codesandbox
Change progress bar component to:
<div style={containerStyles}>
<div style={fillerStyles}>
<div style={circleStyles}>{circleText}</div>
</div>
</div>
And add this styles to the component:
const circleStyles = {
display: "flex",
position: "absolute",
right: "0",
width: "50px",
height: "50px",
background: "blue",
top: "-60%",
borderRadius: "50px",
justifyContent: "center",
alignItems: "center",
color: "white"
};
And here's the App.js:
export default function App() {
return (
<div className="App">
<ProgressBar
bgcolor={item.bgcolor}
completed={item.completed}
circleText={"100%"}
/>
</div>
);
}
add a span under container div and put this style to it
<div style={containerStyles}>
<div style={fillerStyles}></div>
<span style={circleStyle}>{text}</span>
</div>
style
const circleStyle = {
height: 40,
width: 40,
position: "absolute",
right: 0,
backgroundColor: bgcolor,
borderRadius: "50%",
top: -10,
display: "flex",
alignItems: "center",
justifyContent: "center",
color: "white"
};
and then put this to containerStyle
position: "relative",
I'm working on a react. The code below is an example. ArrayExample is mapped and returned to the div component. Whenever I click the mapped div component, I want to change the value of the top of div (position: 'absolute') and place it on the right side according to the mapped div topBorder. Is there a way? I want to move it smoothly like an animation.
import React from "react";
const sample = () => {
const arrayExample = ["AAAA", "BBBB", "CCCC"];
return (
<div
style={{
display: "flex",
flexDirection: "column",
width: "100%",
height: "500px",
alignItems: "center",
justifyContent: "center",
backgroundColor: "#f3f3f3",
}}
>
{arrayExample.map((v, i) => {
return (
<div
style={{
width: "50%",
padding: 50,
border: "1px solid black",
marginTop: 15,
}}
onClick={() => {
console.log("Event!")
}}
>
{v}
</div>
);
})}
<div style={{position: 'absolute', top: 70, right: '22%', backgroundColor: "#4285F4", width: 50, height: 150, borderRadius: 5}}>
moving screen(I want to Change top value)
</div>
</div>
);
};
export default sample;
On click of the item div, you need to figure out the distance of that div from the top, and then change the top css property of your right div according to that. To find this distance you can use offsetTop property. For animation you can use transition property. Here is the code:
import React, { useRef } from "react";
const Sample = () => {
const arrayExample = ["AAAA", "BBBB", "CCCC"];
const rightDiv = useRef();
const itemClickHandler = (i) => {
const newTopHeight = document.getElementById("container").children[i].offsetTop;
rightDiv.current.style.top = newTopHeight + 'px';
}
return (
<div
id="container"
style={{
display: "flex",
flexDirection: "column",
width: "100%",
height: "500px",
alignItems: "center",
justifyContent: "center",
backgroundColor: "#f3f3f3",
}}
>
{arrayExample.map((v, i) => {
return (
<div
key={i}
style={{
width: "50%",
padding: 50,
border: "1px solid black",
marginTop: 15,
}}
onClick={() => itemClickHandler(i)}
>
{v}
</div>
);
})}
<div
ref={rightDiv}
style={{
position: 'absolute',
top: 70,
right: '22%',
backgroundColor: "#4285F4",
width: 50,
height: 150,
borderRadius: 5,
transition: "top 0.5s ease-in-out"
}}>
moving screen(I want to Change top value)
</div>
</div>
);
};
export default Sample;
You can see this in action here: https://codesandbox.io/s/thirsty-curie-7mskj
In your click handler you can get the current position of the clicked div in px, you can easily google how to do this this (relative to the page, not the viewport). I would suggest storing this value in state, call it something like activeItemOffsetTop, then just set top to the current state
I was going to the react router code here: modal-gallery
and came across this syntax
const Modal = ({ match, history }) => {
const image = IMAGES[parseInt(match.params.id, 10)]
if (!image) {
return null
}
const back = (e) => {
e.stopPropagation()
history.goBack()
}
return (
<div
onClick={back}
style={{
position: 'absolute',
top: 0,
left: 0,
bottom: 0,
right: 0,
background: 'rgba(0, 0, 0, 0.15)'
}}
>
<div className='modal' style={{
position: 'absolute',
background: '#fff',
top: 25,
left: '10%',
right: '10%',
padding: 15,
border: '2px solid #444'
}}>
<h1>{image.title}</h1>
<Image color={image.color} />
<button type='button' onClick={back}>
Close
</button>
</div>
</div>
)
}
My Question is, what type of syntax is this? and how would you convert this into ES6 React.Component class
it is a React Stateless Functional Component (React SFC). It's a function, instead of a class.
Basically you don't need/have to convert it to a React.Component class as it's a valid way to declare a React.Component.
A SFC is normally referred to as a dumb component, as it only care about the props passed to it but nothing else. It's a component that is pure (it is not supposed to have any internal state) nor should have any side effects come out from its lifecycle functions.
React recommends that if you don't need internal state, nor lifecycle methods with your component, you should write it as a SFC.
You can have a further look here:
https://reactjs.org/docs/components-and-props.html
This is a pure function. You can look at it as just the render function of a React.Component.
Converting it then becomes easy, just paste the code inside you render function:
class Modal extends React.Component {
render() {
const { match, history } = this.props; // Here you get your props
const image = IMAGES[parseInt(match.params.id, 10)]
if (!image) {
return null
}
const back = (e) => {
e.stopPropagation()
history.goBack()
}
return (
<div
onClick={back}
style={{
position: 'absolute',
top: 0,
left: 0,
bottom: 0,
right: 0,
background: 'rgba(0, 0, 0, 0.15)'
}}
>
<div className='modal' style={{
position: 'absolute',
background: '#fff',
top: 25,
left: '10%',
right: '10%',
padding: 15,
border: '2px solid #444'
}}>
<h1>{image.title}</h1>
<Image color={image.color} />
<button type='button' onClick={back}>
Close
</button>
</div>
</div>
)
}
}
I’m having trouble aligning two components within another div in React. I’m using relative positioning for the parent div (snippetButtonHolder) and absolute positioning for its children (snippet and button). I want snippet to be centered in the parent and button to be under snippet and to the right, but for some reason when I use these attributes they are positioned relative to the entire page, not to the parent div. Does anyone have a suggestion as to what I should do differently?
const styles = {
module: {
marginTop: '30px',
padding: '20px',
},
snippet: {
backgroundColor: '#f2f2f2',
border: 'solid 1px #ccc',
borderRadius: '4px',
margin: '0 auto',
padding: '10px',
width: '100%',
position: 'absolute',
left: '50%',
},
snippetButtonHolder: {
width: '95%',
position: 'relative',
},
button: {
float: 'right',
marginTop: '5px',
position: 'absolute',
left: '94%',
},
};
export default class CodeSnippet extends Component {
constructor(props) {
super(props);
}
render() {
return (
<div style={styles.module}>
<div style={styles.snippetButtonHolder}>
<div style={styles.snippet}>
<div
{'text will go here'}
</div>
{this.state.showButton ?
<button
style={styles.button}>
Press me
</button>
: null}
</div>
</div>
</div>
);
}
}
Give this a try:
const styles = {
module: {
marginTop: '30px',
padding: '20px',
},
snippet: {
backgroundColor: '#f2f2f2',
border: 'solid 1px #ccc',
borderRadius: '4px',
display: 'inline-block',
overflow: 'hidden',
padding: '10px',
},
snippetButtonHolder: {
textAlign: 'center',
width: '95%',
},
button: {
float: 'right',
marginTop: '5px',
},
};
I am trying to create custom header in React.js. I have a working prototype in this JSFiddle.
The problem is, React does not go well with css pseudo-elements, so following this advice I tried to "translate" it into React component:
var lineAfterStyle = {
position: 'absolute',
top: '51%',
overflow: 'hidden',
width: '50%',
height: '1px',
content: '\a0',
backgroundColor: 'red'
};
var lineBeforeStyle = {
position: 'absolute',
top: '51%',
overflow: 'hidden',
width: '50%',
height: '1px',
content: '\a0',
backgroundColor: 'red',
marginLeft: '-50%',
textAlign: 'right',
};
......
<div>
<div style={lineBeforeStyle} />
<h1 style={headerStyle}>Hello World!</h1>
<div style={lineAfterStyle} />
</div>
This does not work as expected--horizontal lines are placed somewhere on the screen and they are NOT inlined with the header. Is there any way to make it better?
