Component Selectors, Content Projection, and Host Bindings

Short summary

Angular supports three component selector types: element, attribute, and class. Content projection via ng-content enables components to render parent-provided content in named slots using CSS selectors. Host bindings and :host pseudo-class allow components to style themselves while maintaining encapsulation.

• •Three selector types for different use cases: element creates new DOM nodes, attribute enhances existing elements, class targets by CSS class
• •ng-content with select attribute routes parent content to named slots; unmatched content falls to default slot
• •:host and ViewEncapsulation control component styling and DOM isolation patterns
