Property Binding: Set HTML Attributes the Angular Way

Property binding lets you set HTML properties using component data. ## Example: disable a button ```html <button [disabled]="isSaving">Save</button> ``` ```ts export class SaveComponent { isSaving = true; } ``` When `isSaving` is true, the button becomes disabled. ## Example: image src ```html <img [src]="avatarUrl" alt="Avatar" /> ``` ```ts export class AvatarComponent { avatarUrl = 'https://example.com/avatar.png'; } ``` ## Class binding (clean styling) ```html <p [class.active]="isActive">Status</p> ``` ```ts export class StatusComponent { isActive = true; } ``` > Next: Two-way binding with ngModel (simple forms quickly).
