Styling Components
UI components can optionally include CSS styles that target their elements in the Document Object Model (DOM).
Code Snippet
Style Scoping
Each component controls how its styles affect the page layout. This is called "view encapsulation." There are three options: Emulated (most common), Shadow DOM (advanced), and None (for special cases). You choose the option when creating the component.
Code Snippet
@Component({
selector: 'app-styling-components',
templateUrl: './styling-components.component.html',
styles: img { border-radius: 50%; }, //styling example,
encapsulation:ViewEncapsulation.None
})
export class StylingComponentsComponent {
}
ViewEncapsulation.Emulated
By default, Angular keeps a component's styles to itself, preventing them from accidentally affecting other parts of your app. This is called "emulated encapsulation." It works by giving each component a special code that gets secretly added to its elements. This code then tells the styles who they can actually apply to. This way, styles don't leak out and mess with other components. However, styles defined globally (outside of components) can still influence elements within a component using emulated encapsulation.
ViewEncapsulation.ShadowDom
Shadow DOM is a more advanced option for keeping component styles isolated. However, it goes beyond just styles and can affect how events work, how you interact with certain features, and how components appear in developer tools. Before using Shadow DOM, it's important to understand these additional impacts to make sure it's the right choice for your project.
ViewEncapsulation.None
This mode disables all style encapsulation for the component. Any styles associated with the component behave as global styles.
