title: Supress Lint Warnings : StyleLint SCSS
body: <p>I new to linting in scss file, I have a angular project with following scss file</p>
  <pre><code>p {
    margin-left: 10px;
    margin-top: 9px;
  }
  
  ::ng-deep .expandButton {
    margin: 10px;
    color: teal;
    border: none;
    background: transparent;
  }
  
  a.mat-list-item.ng-tns-c1-0.active {
    background : #eff0f1;
    font-weight: bold;
    color: black;
    border-right: 3px solid teal;
  }
  </code></pre>
  <p>and a <strong>.yml</strong> file for lint rules,</p>
  <pre><code>rules:
    declaration-no-important: null  
    scss/at-rule-no-unknown: null
  </code></pre>
  <p>while building the code or executing the following command  <code>stylelint **.scss</code>, I'm getting the following errors,</p>
  <pre><code> 1:1  ×  Unknown rule at-rule-disallowed-list                     at-rule-disallowed-list
   1:1  ×  Unknown rule declaration-property-value-disallowed-list  declaration-property-value-disallowed-list
  </code></pre>
  <p>How to fix/suppress this warning, the build passes, there are no errors, but these two lines, keep on occurring for all the scss files.</p>
