title: ng-class with multiple conditions
body: <p>I want to show the class based on the value present in it.</p>
  
  <pre><code>ng-if="data.percentage &gt;= 0  &amp; data.percentage &lt; 25"
  ng-if="data.percentage &gt;= 25 &amp; data.percentage &lt; 50"
  ng-if="data.percentage &gt;= 50 &amp; data.percentage &lt; 75"
  ng-if="data.percentage &gt;= 75 &amp; data.percentage &lt;= 100"
  
  .firstLabel
  .secondLabel
  .thirdLabel
  .fourthLabel
  </code></pre>
  
  <p>For example, if the value in <code>data.percentage</code> is 75 then my output div should look like this.</p>
  
  <pre><code>&lt;div ng-class="fourthLabel" &gt; &lt;/div&gt;
  </code></pre>
