Is it possible in Drupal 8, to add a CSS class to the <body> tag based on the current path alias?

1 Answer 1


In your theme, you can add the following code in template_preprocess_html:

$current_path = \Drupal::service('path.current')->getPath();
$path_alias = \Drupal::service('path_alias.manager')->getAliasByPath($current_path);
$path_alias = ltrim($path_alias, '/');
$variables['attributes']['class'][] = \Drupal\Component\Utility\Html::cleanCssIdentifier($path_alias);
