🎞️ AngularJS Animations with ngAnimate

To enable animations:

angular.module('myApp', ['ngAnimate']);

Wrap animated elements with directives like ng-if or ng-show, then define CSS classes:

<div ng-if="show" class="panel">Content</div>

.panel.ng-enter { opacity: 0; }
.panel.ng-enter-active { transition: opacity 0.5s; opacity: 1; }
.panel.ng-leave { opacity: 1; }
.panel.ng-leave-active { transition: opacity 0.5s; opacity: 0; }

✅ You may also use JS hooks ($animateProvider) for advanced logic.

🧰 AngularJS Material Components

By including Angular Material, you gain access to styled, ready-to-use UI elements:

1. Datepicker: <md-datepicker ng-model="selectedDate"></md-datepicker>
2. Paginator: <md-pagination md-total="{{ totalItems }}" md-page="currentPage" md-on-paginate="loadPage(page)"> </md-pagination>
3. Dropdown Menu: <md-select ng-model="choice"> <md-option ng-value="opt" ng-repeat="opt in options">{{opt}}</md-option> </md-select>

✅ Styling and theming are handled by Angular Material’s $mdThemingProvider and CSS.
