Can a designated Angular2 component be customized with CSS in terms of its appearance while employing ViewEncapsulation?

I am looking for a way to dynamically change the appearance of Angular2 components with just the click of a button, making them appear completely different each time. This is similar to implementing various CSS "Skins" or "Themes". It would also be convenient if new "Skins" could be incorporated later on.

While I am aware that setting ViewEncapsulation.None and using interchangeable CSS files is an option, I am curious if there is a method to achieve this using ViewEncapsulation.

If anyone has any advice or suggestions on how this can be accomplished, I would greatly appreciate it! Thank you, Markus

Answer №1

To customize the styling of your components based on a specific theme, you can use the following code:

@HostBinding('attr.theme') theme = this.globalService.theme;

This code allows you to apply different styles depending on the value of the class specified.

:host([theme="dark"]) {
  color: lightgrey;
  background-color: black;
}

:host([theme="light"]) {
  color: black;
  background-color: white;
}

It's important to note that component styles cannot be dynamically added or removed at runtime.

If you decide to add styles directly to the index.html file, keep in mind that it will compromise the encapsulation of styles (especially when using ViewEncapsulation.Emulated as the default setting), but it does allow more flexibility in adding or removing styles as needed.
