title: How to insert fa-fa icon to search form
body: <p>I need a little help with a search form icon. The button tag class <code>&lt;i class="fa fa-search"&gt;&lt;/i&gt;&lt;/button&gt;</code> doesn't work:</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-html lang-html prettyprint-override"><code>&lt;form role="search" method="get" class="search-form" action="&lt;?php echo home_url(); ?&gt;" onsubmit="check_search();return false;"&gt;
    &lt;label&gt;
      &lt;input type="search" class="searchfieldz" placeholder="Search anything " value="" name="s" title="Search for:" autocomplete="off"&gt;
    &lt;/label&gt;
    &lt;button type="submit" class="searchButton"&gt;
      &lt;i class="fa fa-search"&gt;&lt;/i&gt;
    &lt;/button&gt;
  &lt;/form&gt;</code></pre>
  </div>
  </div>
  </p>
