Angular5 - set color of div container dynamically

Question

With AngularJS this worked fine:

<div style="width:10px;height:10px;background-color:{{user.color}}"></div>

but with Angular5 it doesn't. How to do it with Angular5?

Answer 1

<div style="width:10px;height:10px;" [ngStyle]="{'background-color': user.color}">...</div>

or

<div [style.background-color]="user.color">...</div>
