Sending a CSS class to an Angular library

In my development process, I am currently working on creating a library using Angular CDK specifically for custom modals. One feature I want to implement is the ability for applications using the library to pass a CSS class name along with other modal configurations. This way, I can easily apply the specified class within the library like this:

this.overlayContainer.getContainerElement().classList.add(modalConfig.overlayContainerClass);

Although I can confirm that the class is being applied to the element, it seems that the class itself is not present.

<div class="cdk-overlay-container overlay-material-design-theme mat-typography custom">

I have already defined the ".custom" class in the application component's CSS file:

.custom{
  width: 100%;
}

My main question revolves around how the CSS styles from the application component can be accessed and utilized in the library component effectively?

Answer №1

In order for CSS classes to function in that manner, they need to be placed where view encapsulation is not enforced.

This is typically done in the src/styles.scss file.

If more organization is desired, the classes can be stored in a separate SCSS file that is imported into src/styles.scss.
