How can I limit the scope of Bootstrap CSS to a specific Angular component?

Has anyone successfully isolated Bootstrap's css file to just one Angular component?

I've encountered issues when including the file globally in styles.css or in .angular-cli.json, as the global styles affect other components that shouldn't be using bootstrap. I attempted to import it from the component's CSS file, but the styles didn't display correctly...

My current setup involves Angular 5 and Angular Cli 1.7.2.

To specify the encapsulation strategy, you can utilize the encapsulation property and set it specifically to ViewEncapsulation.Native for your particular scenario.

@Component({
// ...
encapsulation: ViewEncapsulation.Native,
styles: [
  // ...
]
})
export class HelloComponent {
// ...
}

With Native encapsulation, styles from the main HTML file do not affect the component. The styles defined within this component's @Component decorator are contained within this component exclusively. For more details, check out this information on View Encapsulation.
