Why is my innerHTML not respecting styles in Angular and how can I fix it?

innerHTML Not Respecting Styles in Angular

In Angular, using innerHTML to display HTML can pose a styling issue, particularly when attempting to apply CSS styles within the HTML code. This behavior occurs because Angular's default encapsulation mode (Emulated) prevents external styles from interfering with the component's internal styles.

Solution:

To resolve this issue and enable styling within innerHTML, you need to switch the encapsulation mode to None. This allows Angular to apply styles from both internal and external sources:

1. Import the ViewEncapsulation enum from @angular/core.
2. In your Angular component, set the encapsulation property to ViewEncapsulation.None.
3. Define your styles using either inline styles in your component's template or an external CSS/SCSS/LESS file. Angular will automatically add them to the DOM.

Example:

<code class="typescript">import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  selector: 'example',
  styles: ['.demo {background-color: blue}'],
  template: '<div [innerHTML]="someHtmlCode"></div>',
  encapsulation: ViewEncapsulation.None,
})
export class Example {
  private someHtmlCode = '';

  constructor() {
    this.someHtmlCode = '<div class="demo"><b>This is my HTML.</b></div>';
  }
}</code>

With this approach, you can now apply CSS styles to HTML rendered through innerHTML in your Angular app.
