Custom 404 page

To render a 404 error page in the root of your site, create a 404 template in the root of the layouts directory. For example:

{{ define "main" }}
  <h1>404 Not Found</h1>
  <p>The page you requested cannot be found.</p>
  <p>
    <a href="{{ .Site.Home.RelPermalink }}">
      Return to the home page
    </a>
  </p>
{{ end }}

For multilingual sites, add the language key to the file name:

layouts/
├── 404.de.html
├── 404.en.html
└── 404.fr.html

Your production server redirects the browser to the 404 page when a page is not found. Capabilities and configuration vary by host.
