Using Css Modules How Do I Define More Than One Style Name

CSS Modules are a powerful tool that allow developers to encapsulate styles within components, preventing conflicts and making it easier to manage styles across larger projects. However, defining multiple style names within a CSS Module can sometimes be a bit tricky for those who are new to this approach.

When working with CSS Modules, each class name you define is automatically scoped to the component it belongs to, helping prevent styles from bleeding into other parts of your application. This scoping mechanism is one of the key features of CSS Modules and ensures a cleaner and more maintainable styling structure.

To define more than one style name within a CSS Module, you can simply separate each class name with a space. For example, if you want to define two classes, you can do so like this:

Css

.className1 {
  /* styles for className1 */
}

.className2 {
  /* styles for className2 */
}

In your component file where you import and use these styles:

Javascript

import styles from './styles.module.css';

function MyComponent() {
  return (
    <div>
      {/* Content of your component */}
    </div>
  );
}

By concatenating the class names with a space in the `className` attribute, you can apply both styles to the specific element in your component. This technique allows you to combine multiple styles from your CSS Module and apply them selectively to different elements within your components.

If you prefer to keep your styles more organized, you can also define a new class within the CSS Module that combines the styles of the individual classes. For example:

Css

.combinedClass {
  composes: className1 className2;
  /* Additional styles for the combined class */
}

Then, in your component:

Javascript

import styles from './styles.module.css';

function MyComponent() {
  return (
    <div>
      {/* Content of your component */}
    </div>
  );
}

By using the `composes` property with CSS Modules, you can create a new class that inherits styles from multiple existing classes, providing a cleaner and more efficient way to manage and apply styles in your components.

In conclusion, defining more than one style name within a CSS Module is easily achievable by separating class names with a space or by composing a new class that combines styles from individual classes. This approach helps maintain a modular and scalable styling system in your projects, improving code organization and making it easier to style components without worrying about conflicts or naming collisions.
