title: Keep selected language between different pages
body: <p>I have a simple html website with different html pages. I'm using <a href="https://www.i18next.com/" rel="nofollow noreferrer">i18n</a> translation in javascript.
  How can I keep the selected language between different pages?</p>
  
  <pre><code>&lt;li class="hidden"&gt;
          &lt;a href="index.html"&gt;&lt;/a&gt;
  &lt;/li&gt;
  &lt;li&gt;
          &lt;a href="quemsomos.html" data-i18n="menu_whoweare"&gt;Quem Somos&lt;/a&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>Thank you</p>
