How to add padding within React Modal? - css

Question

I'm building my first React modal. The basic structure is now done but I want to have more padding in between the border and the contents. I thought this would be simple but I've tried several things and none work.
return (
<div className={classes.backDrop}>
<Modal
backdrop={'static'}
size='lg'
show={true}
centered={true}
style={classes.modalContainer}
data-testid='addFleetCustomerModal'
>
<div className='modalContainer'>
<ModalHeader>
</ModalHeader>
<Modal.Body>
<Modal.Title>
Add Customer
</Modal.Title>
<Form.Group>
<Form.Label className={classes.highlight}>Company Name*</Form.Label>
<Form.Control id='companyName' data-testid='companyName' type='text' placeholder='For example: ABC Corp.'
/>
</Form.Group>
<Form.Group>
<Form.Label>
<strong>NOTES</strong><br/>
Notes added here can only be viewed and edited by other team members.
</Form.Label>
<textarea className="form-control" id="companyNotes" rows="3"></textarea>
</Form.Group>
</Modal.Body>
<Modal.Footer>
<Row>
<a href='/#'>Cancel</a>
<Button variant='secondary' size='sm'> Next </Button>
</Row>
</Modal.Footer>
</div>
</Modal>
</div>
);
Any ideas on what CSS I should add (and where) to move the content of the modal inward a bit more?

Answer 1

add this to your css:
.modal-header,
.modal-body,
.modal-footer {
padding: 2rem; //change the padding as you want
}
this will change the padding but the with full width lines between sections.
See Working demo 1
you can also add the padding around the whole modal but this this won't make the lines full width:
.modal-content {
padding: 2rem;
}
See Working demo 2

Answer 2

My apologies, everyone. I must have been really tired yesterday afternoon when I posted this. Let me explain the solution:
The code I posted above is inside a functional component that is defined like this:
const AddCustomer = ({ classes }) => {
classes comes from the parent component, which is defined like this:
class UserMgmtPage extends React.Component {
In this parent component, the CSS styleSheet is injected into via react-jss code. I then pass does these same CSS classes into functional child component.
You'll notice this 2nd line, which was always working:
<div className={classes.backDrop}>
My failure was to use the same syntax. Thus the solution is this:
<div className={classes.modalContainer}>
Sorry for the trouble but I do appreciate everyone who tried to help!
