Why not to interact with the DOM directly in Angular?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have read that it is not wise to interact with the DOM directly both for security and performance. Avoiding using syntax like below to select Elements.
const itemToManipulate = document.getElementById('example');
So I read a good work around is to use ElementRef Directive.
But go on to find the Angular Documents advise against this because of tight coupling, what is tight coupling?
Found in documentation here
I settled for using a ViewChild, like so...
@ViewChild('itemToManipulate') public item: ElementRef<any>;
Does this lead to any unwanted behaviour I should be concerned about (security / performance wise) and is there a best practice for interacting with the DOM, or should this not be done within Angular (6 / 7)?
Thanks in Advance.

in addition to @PankajParkar's video which you should definitely watch, there's a big security risk in directly manipulating the dom, via renderer or native, a manual sanitation is required on many cases. so in short, don't go that way. stick to the angular way of doing stuff.
