Using CSS Modules: How Do I Define More Than One Style Name?

When working with CSS modules, it is common to define multiple style names for a single element. This allows you to apply different styles to the same element based on different conditions or states. In this blog post, we will explore two common approaches to defining multiple style names using CSS modules.

Approach 1: Using Array Syntax

One way to define multiple style names in CSS modules is by using an array syntax. This approach allows you to apply multiple styles to an element by specifying an array of style names.

    .container {
      composes: [styleNameA, styleNameB] from './styles.module.css';
    }
  

In the above example, the composes keyword is used to import the styles from the styles.module.css file and apply the styleNameA and styleNameB styles to the .container element.

Approach 2: Using Template Literals

Another approach to defining multiple style names in CSS modules is by using template literals. This approach allows you to concatenate multiple style names into a single string and apply them to an element.

    .container {
      composes: ${styleNameA} ${styleNameB} from './styles.module.css';
    }
  

In the above example, the composes keyword is used along with template literals to concatenate the styleNameA and styleNameB styles into a single string and apply them to the .container element.

Conclusion

Defining multiple style names using CSS modules can be achieved through the use of array syntax or template literals. Both approaches allow you to apply multiple styles to an element, giving you more flexibility in styling your JavaScript applications.

Remember to import the CSS module file and use the composes keyword to apply the desired styles to your elements. Experiment with both approaches and choose the one that best suits your project’s requirements.
