title: Change titles tag (tab) background color
body: <p>I have simple page:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
   &lt;head&gt;
  &lt;meta charset="UTF-8"&gt;
  &lt;title&gt;Document&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
     Text
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I need to change title (browser tab) background color.
  I tried it:</p>
  
  <pre><code>&lt;meta name="theme-color" content="#ef2c1a"&gt;
  </code></pre>
  
  <p>And another way:</p>
  
  <pre><code> &lt;style&gt;
      title{
          background-color: red;
      }
  &lt;/style&gt;
  </code></pre>
  
  <p>But it doesn't work. 
  What another ways are?
  Please, help me to solve it, thanks</p>
