In Angular Doc https://angular.io/docs/ts/latest/guide/ngmodule.html

Under heading “Declare directives and components”. There is an example of file app/highlight.directive.ts that sets the background color of element by using

renderer.setElementStyle(el.nativeElement, ‘backgroundColor’, ‘gold’);

Problem is there isn’t any such property known as “backgroundColor”. Its actually “background-color”.

Please correct your documentation.

Please tell us about your environment:

• Angular version: 2.0.X
