How to pass padding/margin as props in React-Bootstrap components - reactjs

Question

I am trying to apply margins and paddings with React-Bootstrap as props.
I passed the docs through but haven't found any mention adding padding or margin in there as it is in official bootstrap docs (3th and 4th). I know it doesn't support well Bootstrap 4, so tried with both.
I tried to pass params as p={1}, paddingxs={5} or mt='1' but it doesn't recognize any of them. More over tried to find any Spacing element in React-Bootstrap folder, but failed.
Paddings and margins work as classnames. But I feel there must be a way to it without Bootstrap classes. There must be a kind of property.

Answer 1

First include bootstrap CSS in your src/index.js or App.js
import 'bootstrap/dist/css/bootstrap.min.css';
Then you can style your component by passing desired bootstrap CSS class name as className prop in React, for example:
import React from "react"
import Container from "react-bootstrap/Container";
function MyComponent() {
return (
<Container fluid className="p-0">
<SomeOtherComponent />
</Container>
);
}
export default MyComponent
Above code will add p-0 CSS class to Container.

You can add margin and padding by using default React's style:
const divStyle = {
marginLeft: '10px',
};
function HelloWorldComponent() {
return <div style={divStyle}>Hello World!</div>;
}

The answer is: there is no props from React Bootstrap to use margins/paddings.
You can use props for col class, but no for margins.
Example:
<Col className="col-6 col-md-3 mb-3 pt-2">
// there you have a Col component from React-Bootstrap 4
// it has some grid system classes, that you can use as props like this:
https://react-bootstrap.github.io/layout/grid/
<Col xs={6} md={3} className="mb-3 pt-2">
// but as you can see, the native classes of Bootstrap 4 like
// mt, mb, pt, pb etc, they have not a props use with
// React-Bootstrap, you have to use them like regular classes
// inside "className"

Answer 4

You'll want to add className="p-5" to the element. This isn't documented in react-bootstrap but it's in the original Bootstrap 4 documentation here: https://getbootstrap.com/docs/4.4/utilities/spacing/#examples

Answer 5

Usually, I'm able to add custom styles to React Bootstrap components by just adding them to the style param. I've put together a short example below, hope this helps.
import React from 'react';
import { Button } from 'react-bootstrap';
const styles = {
myCoolButton: {
paddingTop: "10vh",
paddingBottom: "10vh",
paddingRight: "10vw",
paddingLeft: "10vw"
}
}
const ReactButton = (props) => {
return (
<Button style={styles.myCoolButton} onClick={()=> {
console.log("Do something here!")
}}>Click Me!</Button>
);
}
export default ReactButton
You can also pass custom components (including those from react-bootstrap) into the styled-components constructor if you prefer to do it that way.

None of the jQuery-free implementations of Bootstrap (React Bootstrap, BootstrapVue or ngBootstrap) have implemented utility directives for spacing (margin/padding), simply because Bootstrap have made it unnecessary in the vast majority of cases, by providing a very intuitive set of Spacing utility classes.
All you need to do is apply the desired class.
To apply utility classes selectively, based on responsiveness interval (media queries), you could use a useMedia hook, as demoed here.
In a nutshell:
const interval = useMedia([
"(min-width: 1200px)",
"(min-width: 992px)",
"(min-width: 768px)",
"(min-width: 576px)"
],
["xl", "lg", "md", "sm"],
"xs"
);
(Based on useMedia from useHooks/useMedia).
You can now reuse this hook throughout your app to add media interval based logic.
Example usages:
// interval === 'sm' ? a : b
// ['xs', 'sm'].includes(interval) ? a : b
// negations of the above, etc...
Important: this particular implementation returns the first matching media query in the list.
If you need to map various media queries, to an object/map with true/false values, you'll need to modify getValue fn to return the entire list, along these lines:
const getValue = () => {
const matches = mediaQueryLists.map(mql => mql.matches);
return values.reduce((o, k, i) => ({...o, [k]: matches[i]}), {})
};
Working example here.
Obviously, you could expand on it and add/remove queries. However, be warned each query adds a separate listener so it could impact performance.
In most cases, the return of the first matching query (first example) is enough.
Note: if the above useMedia hook is not enough for your use case, a more robust and heavily tested solution for media-query listeners in JS is enquire.js. It's easy to use, incredibly light and thoroughly tested cross-browser/cross-device. I have no affiliation with it, but I have used it in various projects over the course of more than a decade. In short, I couldn't recommend it more.
Back to Bootstrap 4: in order to customize the $spacer sizes, follow the guide provided under Bootstrap's theming as it's actually about more than what we typically call theming (changing colors), it's about overriding default values of Bootstrap's SASS defaults, including responsivenss breakpoints, spacers, number of columns and many, many others. The one you're interested in is $spacer.
Simply write the overrides into an .scss file and import it in your root component. Example.
Note: a (simpler and more intuitive) option to customize Bootstrap is to do it visually, using bootstrap.build but it's typically a few minor versions behind (i.e. Bootstrap is now at v4.4.1 and the build tool is at v4.3.0).
The build customizer provides intuitive controls and real time visualization.
It allows export as .css or .scss.

Just try this out once according to your input and still if face any issue you can reach out.In below we have increased the .col padding with .px-md-5 and then countered then with .mx-md-n5 on the parent .row.
JSX:
import React from 'react'
import { MDBContainer, MDBRow, MDBCol } from 'mdbreact';
const SpacingPage = () => {
return (
<MDBContainer>
<MDBRow className="mx-md-n5">
<MDBCol size="6" className="py-3 px-md-5">Custom column padding</MDBCol>
<MDBCol size="6" className="py-3 px-md-5">Custom column padding</MDBCol>
</MDBRow>
</MDBContainer>
)
}
export default SpacingPage;
If you still have any kind of doubt on this then feel free to ask .
