title: Fix Warning "Also define the standard property 'box-shadow' for compatibility"
body: <p>I use the MDB scroll library, and VSCode shows the following warning:</p>
  <blockquote>
  <p>Also define the standard property 'box-shadow' for compatibility</p>
  </blockquote>
  <p>How can I fix it or at least ignore the warning on VSCode?</p>
  <pre class="lang-css prettyprint-override"><code>.scrollbar-black::-webkit-scrollbar-thumb {
      border-radius: 10px;
      -webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.1);
      background-color: #000;
  }
  </code></pre>
