问题 Here's the problem. I have three states of almost all the pages in my app. 1. Loading (where I want to show spinner within the page and for that I have created a component already) 2.

Thats how I am doing this currently which doesnt look great on every page. <app-spinner *ngIf="!data; else page_content">
