title: Multiple conditions on ngstyle
body: <p>I would like to if possible add multiple conditions to ng style</p>
  
  <p>Currently I set the width and color like this</p>
  
  <pre><code>[ngStyle]="{
                'width': (question.score.toFixed(1) * 10)+'%', 
                'background-color': question.score.toFixed(1) &lt; 3 ?'red' : '#00c9c7' 
                }"
  </code></pre>
  
  <p>However I want to score under 3 are red, and over 7 are green. This condition gives me under 3 are red, anything else is turquoise. Are you able to add multiple conditions to ng style? </p>
