Access HTML content including styles using Angular

I have created an Angular application and I am looking to extract the html of a template from a large component, including the styles applied to the classes used. Can anyone advise on how to achieve this in Angular? Currently, I am attempting to use the following code snippet with innerHTML:

const myTemplate = document.getElementById("someWrapperId");
const content = myContent.innerHTML;

However, this method does not return the styled html. I have also experimented with setting 

encapsulation: ViewEncapsulation.None
, but this has not solved the issue either. The styles are defined in a separate component.css file and are not set inline.

Hey there, I believe you can access the HTML content style using @ViewChild and ElementRef. Check out the code snippet below for a demonstration:
HTML:

<div  #infoDiv class='col-md-2' style='color: blue;width:152px'>INFO DIV</div>
<br>
Your Color:: {{styleColor}}
<br>
Your Width:: {{styleWidth}}

TS:

import { Component, ElementRef, ViewChild } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  styleColor:any='';
  styleWidth:any='';
  @ViewChild('infoDiv') infoDivRef: ElementRef;
  ngAfterViewInit(): void {
    if (this.infoDivRef.nativeElement) {
      console.log(this.infoDivRef.nativeElement.style.color);
      this.styleColor=this.infoDivRef.nativeElement.style.color;
       this.styleWidth=this.infoDivRef.nativeElement.style.width;
    }
  }
}

NOTE: The code is accessible on stackblitz as well. Click the following DEMO link to view it.
