angular - 防止将属性选择器添加到具有 Angular 2 的 SaSS 选择器

Question

继续这个问题 SVG is not loaded with Angular 2 ，我将使用 SaSS 代码设计我的 SVG 图标。我制作了这段代码:

svg {
  width: 200px;
}

问题发生在我编译这段代码的时候。编译器总是添加一个属性选择器。像这样:

svg[_ngcontent-noc-7] {
    width: 200px;
}

当我重新加载页面时，noc 总是不同的。这是我的代码:

<div *ngFor="let item of achievements; let i = index" class="achievementscontainer">
    <h3>{{item.name}}</h3>
    <p>{{item.description.replace('%d', item.next)}}</p>
    <div [innerHTML]="transform(item.image)" [class]="item.status"></div>
    <p class="bold">Progress till next achievement:</p>
    <p><span>{{item.progress}}</span>/<span>{{item.next}}</span></p>
</div>

import { Component } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

@Component({
    templateUrl: './profile.component.html',
    styleUrls: ['./profile.component.scss']
})

export class ProfileComponent {

    achievements = [

    ];

    constructor(private sanitizer: DomSanitizer) { }

    transform(html) {
        return this.sanitizer.bypassSecurityTrustHtml(html);
    }
}

如果代码加载到我的页面上，则没有 _ngcontent-noc-7 属性添加到 svg 标签。

所以我的问题是，当页面正在加载时，如何阻止从我的 SaSS 代码向 svg 选择器添加属性？对于这个站点，我使用 Angular 2。

试试这个:

@Component({
    templateUrl: ...,
    styleUrls: ...,
    encapsulation: ViewEncapsulation.None
})
