+### Self-Closing Tags
+
+Angular supports self-closing tags for custom components.
+
+**Rule:** Always use self-closing tags when a component does not contain projected content or child nodes:
+
+```html
+<!-- Preferred: concise and modern -->
+<app-profile />
+<app-user-card [user]="currentUser()" />
+<router-outlet />
+
+<!-- Avoid: redundant closing tags for empty elements -->
+<app-profile></app-profile>
+<app-user-card [user]="currentUser()"></app-user-card>
+<router-outlet></router-outlet>
+```
+
 ## Template Control Flow
 
 Angular uses built-in blocks for conditional rendering and loops.
