I am trying to change the background color for the whole page in Angular(would use body, or html tag when working without framework). and I can't find the best practice for this, I want it to be within the framework if possible since I am building an application for years to come.
If you are using angular-cli.
There should exist a global style file.
In there you should be able to put your style e.g. html { background-color: black; }
to effect the whole page.
