title: sonarqube giving false positive with the rule "Unknown type selectors should be removed" when trying to style a custom HTML tag
body: <p>We have used angular custom directive to generate a custom html tag called .The corresponding style sheet file for this tag is student.scss and its content is </p>
  
  <pre><code>student-result {/* Sonarqube is reporting critical issue at this line saying 
                "Remove the usage of the unknown "student-result" type selector" */
  
  
     .student-result-top {
        position :absolute;
        height :300px;
     }
  }
  </code></pre>
  
  <p>Can anybody suggest any way to resolve the issue or any plugin which will make sonarqube to recognize these custom HTML tags?</p>
