title: Why selector "input:read-only, input:-moz-read-only" won't work on Google Chrome?
body: <p>Why selector <code>input:read-only, input:-moz-read-only</code> won't work on Google Chrome? Works only, if I write it as two separate selectors <code>input:read-only</code>, <code>input:-moz-read-only</code> with same instruction.</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>input:read-only,
  input:-moz-read-only {
    border: 1px solid red;
  }
  
  
  /* Works if i will repeat it separate, like below */
  
  
  /* input:read-only {
      border: 1px solid red;
  } */</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;input type="text" name="" value="Read-only" id="" readonly&gt;</code></pre>
  </div>
  </div>
  </p>
