Angular2 components are not cooperating with the Bootstrap styling

Problem with applying Bootstrap styles to Angular2 components.

The Bootstrap fluid container is not functioning properly in the UI when used within an Angular2 component. However, it works fine if 'container-fluid' is placed inside the component as a div element.

For example, this code does not work:

@Component({
    selector: 'gn-app',
    viewProviders: [],
    moduleId: module.id,
    template:
        `<gn-layout class="container-fluid"
        (window:resize)="gnOnResize($event)"
        </gn-layout>
    `,
   directives: [ROUTER_DIRECTIVES, LayoutComponent]
})

Here is the corrected code that works:

<gn-layout>
   <div class="container-fluid">
      <div class"row">
          <gn-container></gn-container>
      </div>
   </div>
</gn-layout>

Answer №1

When it comes to certain components, browsers may not recognize them as standard HTML elements. This means that default styles won't be applied to them automatically. In order to ensure proper rendering, you need to include display:block in the component.

@Component({
    styles : [`
        :host {
            display: block;
        }
    `]
})

This approach will resolve the issue. For more information, check out this discussion on making display:block a default setting.

Take a look at this Plunker demo for a working example. If you remove the styles property from the component, you'll notice the difference in how the component is displayed.
