Note * that certain aspects of the view can also change which style is used; for * example, arguments which provide a summary view might change the style to * one of the special summary styles. * * The default style for all views is views-view-unformatted.html.twig. * * Many styles will then farm out the actual display of each row to a row * style; the default row style is views-view-fields.html.twig. * * Here is an example of all the templates that will be tried in the following * case: * * View, named foobar. Style: unformatted. Row style: Fields. Display: Page. * * - views-view--foobar--page.html.twig * - views-view--page.html.twig * - views-view--foobar.html.twig * - views-view.html.twig * * - views-view-unformatted--foobar--page.html.twig * - views-view-unformatted--page.html.twig * - views-view-unformatted--foobar.html.twig * - views-view-unformatted.html.twig * * - views-view-fields--foobar--page.html.twig * - views-view-fields--page.html.twig * - views-view-fields--foobar.html.twig * - views-view-fields.html.twig * * Important!
