How Can I Conditionally Apply CSS Styles in AngularJS?

Conditionally Applying CSS Styles in AngularJS

Q1: Dynamically Styling Items Before Deletion

To apply or remove CSS styling conditionally based on checkbox selection, consider using ng-class. It allows you to assign a CSS class based on a boolean value. For example:

<div ng-repeat="item in items">
  <div ng-class="{'pending-delete': item.checked}"></div>
  <input type="checkbox" ng-model="item.checked" />
</div>

Q2: User-Defined Style Personalization

For allowing users to customize site presentation, ng-style is a suitable option. It enables dynamic styling based on a map of CSS properties and values. For instance:

<div class="main-body" ng-style="{ color: myColor }">
  <input type="text" ng-model="myColor" placeholder="Enter a color name" />
</div>
