title: Templating with href in angular (4)
body: <p>So I know that in Angular 2 we can simply substitute ng-href for href in order to make templated urls work, but it doesn't work for me in Angular 4.  I can't find any documentation for it on angular.io either, so how does it work?</p>
  
  <p>Edit: Maybe I have the version #s confused.  I'm concerned with the latest Angular (angular.io)</p>
  
  <p>I want to link to external stylesheets, like 
  <code>link rel="stylesheet" href="..."></code></p>
  
  <p>where ... is {{link}}, link = <a href="https://www.w3schools.com/w3css/4/w3.css" rel="noreferrer">https://www.w3schools.com/w3css/4/w3.css</a></p>
