I had this problem with making responsive image map when I made some map on than in media queries the position of areas was changing so it make me crazy than I found this way
what is the way?
I was searching for long day that how I should write a code that links should not change when the position of an image changed in media queries so I found this way the best.
first go to this https://zaneray.com/responsive-image-map/ website and add your local image address from the webpage that you are working than add links in every place of your image that you want
add a div before your image and make it position relative
add the img tag and copy all the urls from that site
<div className="Afghan-map">
<img src={map} className="Afg-map" />
<a
href="your url"
title="Balkh"
className="balkh province"
/>
<a
href="hyour url"
title="Jallab abbad"
className="jallal-abbad province"
/>
<a
href="your url"
title="Badghis"
className="badghis province"
/>
<a
href="your url"
title="Kabul"
className="kabul province"
/>
<a
href="your url"
title="Herat"
className="herat province"
/>
</div>
than add your style like this.
.Afghan-map {
position: relative;
.province {
position: absolute;
z-index: 2;
}
.balkh {
left: 44.83%;
top: 21.83%;
width: 7.48%;
height: 12.1%;
}
.jallal-abbad {
left: 63.27%;
top: 43.55%;
width: 5.71%;
height: 6.25%;
}
.badghis {
left: 25.39%;
top: 34.82%;
width: 10.42%;
height: 10.22%;
}
.kabul {
left: 57.41%;
top: 41.57%;
width: 4.48%;
height: 5.56%;
}
.herat {
left: 12.81%;
top: 39.88%;
width: 12.04%;
height: 17.36%;
}
}

I'm relatively new to React and I'm trying to create a sort of dashboard for Cryptocurrency prices.
I'm using react-financial-charts to generate an OHLCV chart within a ResponsiveReactGridLayout.
However, the svg always displays outside the grid. Can anyone help with how I could fix this:
Here is the code: https://github.com/astronights/market_analysis_tool_evaluation-ui/blob/master/src/components/Home/Home.tsx where I render my Component that contains the ChartCanvas.
<div key="candlestick" className="home-card">
<div ref={canvasRef} style={{ width: "100%", height: "100%" }}>
{canvasRef.current ? (
<Candlestick
coin={coin}
width={canvasRef.current.clientWidth}
height={canvasRef.current.offsetHeight}
/>
) : null}
</div>
</div>
and here is the code for the chartCanvas: https://github.com/astronights/market_analysis_tool_evaluation-ui/blob/master/src/components/Home/Candlestick.tsx
return (
<ChartCanvas
height={props.height}
ratio={1}
width={props.width}
margin={{ bottom: 50, top: 100, left: 50, right: 50 }}
padding={0}
seriesName={`OHLCV prices - ${props.coin.coin}`}
data={prices}
xScale={scaleTime()}
xAccessor={xAccessor}
xExtents={xExtents}
/>
As you can see in the image, the SVG chart generated seems to be going outside.
Fixed by adding these lines of CSS.
.react-financial-charts {
position: absolute !important;
top: 0;
left: 0;
}
canvas {
position: absolute !important;
top: 0;
left: 0;
}
How can I set the height of an image in gatsby? My approach was this:
My query:
image {
fluid {
...GatsbyContentfulFluid_withWebp
}
}
My return:
<Img fluid={image.fluid} style={{ maxHeight: '200px' }} alt={title}></Img>
The image is displaying fine but I query more than one image and using style={{ maxHeight: '200px' }} is not working for all images. Some images having different heights, I would like to display all images with the same height.
What's the proper way of doing this?
I think you are looking for a fixed image, not fluid:
My query:
image {
fixed {
...GatsbyContentfulFixed_withWebp
}
}
My return:
<Img fixed={image.fixed} style={{ height: '200px', width: 'auto' }} alt={title}></Img>
In addition, use the height, not the maxHeight property to force all image's height to 200px.
According to the docs you should use imgStyle property for directly applying styles to underlying <img>
Try something like
<Img
fluid={image.fluid}
imgStyle={{ height: '200px', width: 'auto' }}
alt={title}>
</Img>
style is applied to wrapper of <img> and your images might be overflowing it.
I'm new to React Spring and I initially tried this
const strikeProps = useSpring({
textDecoration: "line-through",
from: { textDecoration: "none" },
});
But it's not working. I think there should be a way simulate the CSS solution for this.
The problem here is, that the original CSS solution is uses pseudo element for emulating the strike trough. We can only add react-spring properties for normal html elements. So the most compact way is to create a separate strike through component for this problem. For example:
const StrikeTroughtText = ({ children, weight = 1 }) => {
const props = useSpring({
from: { width: "0%" },
to: { width: "100%" }
});
return (
<div style={{ position: "relative", display: "inline-block" }}>
{children}
<animated.div
style={{
position: "absolute",
top: "50%",
left: 0,
width: props.width,
height: `${weight}px`,
background: "black"
}}
/>
</div>
);
};
We basically animate the width of the absolutely positioned div containing a black line over the text.
You can use it like a div component:
<StrikeTroughtText>text</StrikeTroughtText>
For bigger font size the default 1 px line weight is not enough, so I added a weight property also.
Here is my example: https://codesandbox.io/s/react-strike-trought-text-component-with-react-spring-animation-86cfd?file=/src/App.js
I have problem with Image component in react native. I would like to display specific part of image in some square. F.e:
Let's say, I have image in resolution: 1280x720
private someImage = require('../Assets/someImage.jpg');
I would like to display this image in square component (with constant size)
<View style={{width: 64, height: 64}}>
<Image source={this.someImage}
style={{position: 'absolute', top: 0, left: 0 }} />
</View>
Here comes the first problem: Image goes beyond the square. How can I show only part of my image (but with original resolution).
The second question is:
Is there a way to showing specific fragment of my image? That's men if I set top: -64, left: -64 I would like to see original image move about 64 pixels diagonally.
Jroslaw. this may helpful for you.
const someImage = require('../Assets/someImage.jpg');
class ImageClip extends Components {
...
render() {
return (
...
<View style={{ width: 64, height: 64, overflow: 'hidden' }}> // width and height of image you want display.
<Image
source={someImage}
style={{
top: 24,
left: 32,
}} //position of image you want display.
/>
</View>
...
);
}
}
To show your image with full resolution but with only the section you choose, you will need to display the image within a fixed sized container. This image will also need to be a background-image in the style attribute.
<View style={{background-image: this.someImage, background-position-x: -64px, background-position-y: -64px}}>
Giving " overflow:'hidden' " to the parent view also works for me.
Resize-mode:contain will NOT work, as it will resize your image to fit entirely within the 64x64 container, not what you want in this case.
<View style={{width: 64, height: 64, overflow: 'hidden'}}>
<Image
source={{uri: 'https://picsum.photos/200/300'}}
style={{
height: 200,
width: 200,
top: -50,
left: -70,
}}
/>

I'm trying to replicate http://www.milkbardigital.com.au/ as a learning project in react.
Currently I'm struggling to get the PNG image over the top of the background image.
Here's my code,
import React from 'react';
import {Image} from 'react-bootstrap';
export default React.createClass ( {
render() {
var background = {backgroundSize : 'cover'};
var textStyle = {
position: 'absolute',
top: '50%',
left: '50%'
};
return (
<div style={{width: 'auto'}}>
<Image
style={background} responsive
src="http://www.milkbardigital.com.au/wp-content/uploads/2015/11/Milkbar-Home-Background.jpg">
</Image>
<h1 style={textStyle}>Agile Media Content</h1>
</div>
);
}
});
<Image src="http://www.milkbardigital.com.au/wp-content/uploads/2015/11/Milkbar-Digital-Media.png" responsive/>
This "Image src" I've tried to place inside the above code but it won't work.
Anyone able to work this out?
It's with React Bootstrap!
Thanks,
Edit - - -
I've worked out how to get it slightly on top, now trying to get it put in the right position.
This is the code, ignore the opacity part,
/**
* Created by Hewlbern on 21-Jan-17.
*/
import React from 'react';
import {Image} from 'react-bootstrap';
export default React.createClass ( {
render() {
var background = {backgroundSize : 'cover',
opacity: '0.5',
};
var textStyle = {
position: 'absolute',
top: '50%',
left: '50%'
};
var ontop = {
display: 'block',
margin: 'auto',
width: '50%',
};
return (
<div style={{width: 'auto'}}>
<Image
style={background} responsive
src="http://www.milkbardigital.com.au/wp-content/uploads/2015/11/Milkbar-Home-Background.jpg">
</Image>
<h1 style={textStyle}>Agile Media Content</h1>
<Image style={textStyle} responsive src="http://www.milkbardigital.com.au/wp-content/uploads/2015/11/Milkbar-Digital-Media.png" />
</div>
);
}
});
