title: Exclude elements from display none
body: <p>I used the same code in my site: </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.title_hero {
    display: none;
  }</code></pre>
  </div>
  </div>
  </p>
  
  <p>I want to exclude this property for some pages which have the class: id-1 and class: id-2. How to do this?</p>
