Styling Descendants Conditionally in Angular 2

.parent {
  color: blue;
}

.parent * {
  color: red;
}

.child {
  color: black;
}

.grandchild {
  color: green;
}
<div class="parent">
  Parent
  <div>Child
    <div>GrandChild</div>
  </div>
</div>

Imagine a scenario where a property named toggle exists in an Angular component. The goal is to switch the ".parent *" style for its descendants, alternating their color between red and blue based on the toggle state. Is there a way to achieve this using ngClass or ngStyle? If so, could you please provide instructions? Much appreciated!

Answer №1

just use the [class.parent] method

<div [class.parent]="toggle">
 Parent
 <div>Child
  <div>GrandChild</div>
 </div>
</div>

the class parent will only be applied when toggle is set to true.
