Can I pass the tailwind className as props in React?

I made a MessageBanner component, and want to make multiple banners like MessageSuccess(green theme) and MessageError(red theme) out from it. And I tried to pass the classNames of background color, text color, and border color but didn't succeed. Please help.

This is the MessageBanner.tsx.

export const MessageBanner: VFC<Props> = memo(props => {
  const { title, description, bgColor, textColor, borderColor } = props
  return (
    <>
      <div
        className={`${bgColor} ${textColor} ${borderColor} pointer-events-autoborder-t-4 rounded-b  px-4 py-3 shadow-md duration-1000`}
        role='alert'
      >
        <div className='flex'>
          <div>
            <p className='font-bold'>{title}</p>
            <p className='text-sm'>{description}</p>
          </div>
        </div>
      </div>
    </>
  )
})

This is the MessageSuccess component. I tried without '.', like 'bg-green-100' instead of '.bg-green-100' but both didn't succeed.

export const MessageSuccess: VFC = () => {
  return (
    <MessageBanner
      title='Welcome Back'
      description='You have successfully logged in'
      bgColor='.bg-green-100'
      textColor='.green-900'
      borderColor='.border-green-500'
    />
  )
}

I appreciate any help. Thanks in advance.

You'll probably want to start using the classnames package so you can work with conditional classes much easier, but the main problem is that you've included . in your class names: those are only used in class definitions/query selectors, not when you assign classes, so:

export const MessageSuccess: VFC = () => {
  return (
    <MessageBanner
      title='Welcome Back'
      description='You have successfully logged in'
      bgColor='bg-green-100'
      textColor='green-900'
      borderColor='border-green-500'
    />
  )
}

without the . for those three attributes. Then, you can do:

import { classnames } from "classnames";

const MessageBanner = (props) => {
  const classStr = classnames(
    "pointer-events-autoborder-t-4 rounded-b px-4 py-3 shadow-md duration-1000",
    props.bgColor,
    props.textColor,
    props.borderColor
  );
  return <div className={classStr} role="alert">{props.description}</div>
};

export { MessageBanner }

And things should work just fine.
