Altering the CSS of dynamically displayed Angular elements

After implementing the ng2-image-viewer library for my image viewer, I noticed that it dynamically loads several HTML components. I would like to change the CSS of certain elements that are dynamically loaded.

Here is the default setup:

https://i.sstatic.net/I7bmZ.png

Before rendering, the HTML component looks like this:

<div class="image-viewer-container">
    <app-image-viewer 
    [images]="[artURL]"
    [loadOnInit]="true"
    [idContainer]="'idOnHTML'"
    [showOptions]="false"
    >
    </app-image-viewer>
</div>

And after rendering, the HTML component changes to:

<div _ngcontent-pyx-c10="" class="image-viewer-container">
    <!-- More nested HTML structure here -->
</div>

I'm attempting to apply the following styles to the rendered HTML using SCSS but it doesn't seem to be taking effect.

.iv-snap-view{
    visibility: visible !important;
    opacity: 1;
}
.image-gallery-2{
    visibility: hidden;
}

Answer №1

When it comes to encapsulated styles in a component (More information can be found here), there are two options available:

  1. You can create a global stylesheet and define the necessary styles there, or simply copy the global styles into src/styles.css
  2. Another option is to use ::ng-deep. Further details can be found here

By applying the ::ng-deep pseudo-class to a CSS rule, you effectively disable view encapsulation for that specific rule. Any style with the ::ng-deep property applied will become a global style. To restrict the specified style to the current component and its descendants, remember to include the :host selector before ::ng-deep. If you use the ::ng-deep combinator without the :host pseudo-class selector, the style may leak into other components.

Please note: Even though the ::ng-deep method is deprecated, there is currently no alternative provided and its removal has not been scheduled.
