title: Fix viewport width in Chrome
body: <p>I have this code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>body
  {
    margin: 0;
    overflow-y: scroll;
  }
  
  .cont
  {
    width: 100vw;
    height: 100vh;
    background-color: #000;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="cont"&gt;&lt;/div&gt;
  &lt;br&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Chrome (and other browsers with the same engine) ignore the width of vertical scrollbar.</p>
  
  <p>How I can fix it?</p>
  
  <p>Thanks!</p>
