What is Angular's style encapsulation and how does it work?

Angular's style encapsulation is a feature that controls how styles are applied to components. It helps to prevent styles from leaking out of a component and affecting other parts of the application.

Can you explain the different encapsulation strategies available in Angular?

Sure! Angular provides three encapsulation strategies: Emulated, Native, and None. Emulated uses a shadow DOM-like behavior, Native uses the browser's native shadow DOM, and None applies styles globally.

When should I use each encapsulation strategy?

Use Emulated for most cases to avoid style conflicts, Native when you need true shadow DOM features, and None for global styles.

Are there any performance implications with these strategies?

Yes, using Native encapsulation can have performance benefits in some cases, but it may not be supported in all browsers. Emulated is generally safe and performs well.
