how to name templates for same content types I have a Content Type machine name as "aktionsblock_oben" and made some content and get the Content ID as 33 for this one. Now I can use template name as page--node--33.html.twig, but what if I create new content like this where I get another ID? The page--node--33.html.twig won't fire.

My try page--node--aktionsblock_oben.html.twig or aktionsblock_oben.html.twig was a failure.

Any suggestions
By default page.html.twig won't work content type specific pages, you'll have to assign a template file name manually. Check the example below which create a new template name for content type: 

function [THEME_NAME]_theme_suggestions_page_alter(array &amp;$suggestions, array $variables) {
  // Add content type suggestions.
  if ($node = \Drupal::request()-&gt;attributes-&gt;get('node')) {
    array_splice($suggestions, 1, 0, 'page__node__' . $node-&gt;getType());
  }
}


With help of above code, you can use page--node--aktionsblock_oben.html.twig template file as your content type template file.
