We can delete all styles related to the "#language-select" as well I guess.

-      {% for lang in available_locales %}
-        <option
-          {% if locale == lang %} selected="selected" {% endif %}
-          value="{{ source.resolve_link(page, lang)[1] }}">
-          {{ config.get("langnames", lang) }}
-        </option>
-      {% endfor %}
-    </select>
-  </li>
 </ul>
