Tips for customizing the CSS of a child component that has been imported from a different module in Angular 2

I have been using agm-snazzy-window from amg-snazzy-window

There is a mention that I can modify the css class, but when I try to do so, it doesn't seem to work. Here is an example:

map-component.html

   <agm-snazzy-info-window [closeWhenOthersOpen]="true">
         <ng-template>
            My custom snazzy window
         </ng-template>
   </agm-snazzy-info-window>

I wanted to increase the width of the content, so I added this: map-component.scss:

.si-content {
  width: 500px !important;
}

However, it doesn't seem to be working as expected. What am I missing?

Answer №1

::ng-deep .si-content {
  width: 500px !important;
}

By using the ::ng-deep selector in Angular, you are ensuring that the correct ViewEncapsulation.Emulated classes are applied to your styles. Angular doesn't do this automatically because it needs guidance to locate the correct classes in your template.

If you omit ::ng-deep, your style will appear as .si-content[_ngcontent-1], or a similar structure. The [_ngcontent-1] portion is derived from the map-component. By including ::ng-deep in your styles, you are directing Angular to search deeper for the appropriate component such as agm-snazzy-info-window.
