问题 I'm using Angular 8 and bootstrap 4 to build a navbar which changes its color from transparent to dark when a certain amount to scroll happens.

But I cannot unfortunately achieve it. Kindly take a look at my code below: HTML <nav class="navbar navbar-expand-lg fixed-top navbar-transparent" [ngClass]=
