title: Custom error 404 page misconfiguration
body: <p>I have .htaccess file configured:</p>
  
  <pre><code>RewriteEngine On
  ErrorDocument 404 /page-404.html
  </code></pre>
  
  <p>This works fine when I type: www.mydomain.com/whatever-to-get-404-error, but, when I use www.mydomain.com/some_folder/whatever-to-get-404-error I get a page without css. My browser starts to look for css in "some_folder", which of course, do not exist.</p>
  
  <p>Why is this happening and how can I fix it?</p>
