angular-directives

Custom attribute directives in Angular modify element appearance or behavior like highlighting or styling by targeting the DOM element directly. They enable reusable UI logic without creating full components, reducing boilerplate code for common visual interactions.

Structural directives control DOM structure by adding or removing elements like lazy rendering or template outlets, while attribute directives change element appearance or behavior like tooltips or button styling without altering the DOM layout.

Host directives compose multiple behaviors onto components or other directives in Angular for reusability. This pattern allows developers to group distinct DOM interactions and declarative behaviors into a single reusable directive applied across the application.

Use custom structural directives when you need to control DOM structure dynamically, such as implementing portals, lazy rendering, or custom template outlets. They provide declarative behavior management for complex content rendering scenarios where standard components fall short.

Yes, you can create a custom lazy load directive in Angular to defer loading images until they enter the viewport. This structural directive manages dynamic content rendering and optimizes performance by preventing offscreen resources from loading immediately.

Creating a custom appTooltip attribute directive is the best way to add reusable tooltip functionality in Angular. It extends DOM behaviors declaratively, allowing tooltips to be applied to any element through a simple attribute without duplicating boilerplate code.
