unable to set width of a reactjs popup - reactjs

Question

I am using reactjs-popup and it displays its content. But I am unable to set its width. It is not taking effect for some reason. What am I doing wrong?
I have tried width:'50%' and width:'50px'. But it always displays the popup in a very wide huge rectangle. If I resize the whole browser only then the popup reduces in size.
<Popup style={{width:'50%'}}
open={true}
closeOnDocumentClick
keepTooltipInside=".tooltipBoundary"
>
<div className="modal" style={{display:'flex', background: 'radial-gradient(#cde6f9, #6191bf)'}}>
<a className="close">
×
</a>
<div style={{alignitems: 'center', justifycontent: 'center'}}>
<h4>Enter Project Name : </h4>
<input style={{alignitems: 'center', justifycontent: 'center'}} type="text" name="fname"></input><br/><br/>
<button style={{alignitems: 'center', justifycontent: 'center'}} >Create</button>
</div>
</div>
</Popup>

Answer 1

Assuming that the Popup component comes from an external package, try to read the documentation for more styling options.
You can probably also view the component in node_modules/[package_name] folder. Try giving it a className there or style it using the style property.
Finally, you can try wrapping the popup with another element and capture the style using css.
Something like that:
.popup-wrapper {
width: 100%;
}
.popup-wrapper > * {
width: 50%;
}

You can certainly globally update the content styles as other posts here imply. But if you want to set the style for a specific popup...
If you inspect the <Popup HTML, you will see there are two divs. One has a class defined with popup-content and a second named popup-overlay. You can overwrite the styles here using the contentStyle and overlayStyle attributes of any given <Popup.
For example if you want to change the width of the content:
<Popup
...set other attributes here as needed
contentStyle={{ width: '100%' }}
>
Show this content
</Popup>

Answer 3

Wrap the popup in div and give it a class like modalWrapper.
You can target the main popup container div by using this css.
.modalWrapper > div > div {
width: 484px !important;
padding: 24px !important;
border-radius: 10px;
}
