What is the best way to send props to a CSS module in React?

Currently utilizing NextJS, I have a route named about that is displayed through page.js. Within /about/page.js, I am incorporating a component called <Hero /> and aiming to pass a prop to

<Hero heroHeight={'height: 400px'} />

to my CSS module to aid in styling.

Hero.js

'use client';

import styles from '../page.module.css';
import style from './Hero.module.css';

const Hero = ({ heroHeight }) => {
  return (
    <div className={`${styles.pageWidth} ${style[heroHeight.updateTheHeight]`}>

    </div>
  );
};

export default Hero;

Hero.module.css

.updateTheHeight{
  border: 1px solid green;
  /* Aim to pass the prop 'height: 400px' here */
}

The current code is not functioning as intended. I aim to pass the prop value of height: 400px to the .updateTheHeight class. Can anyone assist in identifying the issue in my code? Any guidance is highly appreciated. Thank you!

It seems the issue with the code lies in attempting to combine CSS modules with dynamic styles, which is not the intended use of CSS modules. CSS modules are better suited for static, predefined class names. However, there is a straightforward solution to this problem.

To incorporate dynamic styles, you can make use of inline styles. Inline styles allow you to directly insert JavaScript values into the style attribute.

One way to address this is by modifying your Hero.js file. Instead of trying to apply your prop to a CSS module class, you can directly include it in a style object. Consider the following example:

const Hero = ({ heroHeight }) => {
 const dynamicStyle = {
 height: heroHeight, // Insert dynamic height here
 border: '1px solid green', // Assuming a consistent green border is desired
};

 return (
  <div className={styles.pageWidth} style={dynamicStyle}>
   {/* Your Hero content */}
  </div>
 );
};

When utilizing your Hero component, simply pass the height value as before:

<Hero heroHeight="400px" />

It's not possible to directly pass values to CSS files. However, there are alternative methods to achieve this.

One approach is to utilize the style attribute to dynamically set the height.

'use client';

import styles from '../page.module.css';
import style from './Hero.module.css';

const Hero = ({ heroHeight }) => {
 return (
   <div className={`${styles.pageWidth} ${style[heroHeight.updateTheHeight]`} style={heroHeight}>

   </div>
 );
};

export default Hero;
