Theme hooks can also be used to define a certain subset of pages to add a library to. To use the library, you can either add it to the theme's *.info.ymlįile to make the library used across your entire theme, or add it to an individual template to be used on a single one. You can add an unlimited number of libraries to this file, and one of them can look like this example: my_library_name:version: 1.xcss:theme:css/my_file.css: dependencies:- core/jquery These entries go into a file called your_theme_ In Drupal 8, adding a CSS or JS file is now handled through "libraries", which can be a collection of any CSS or JS in any amount. For naming conventions, you can check out this Drupal guide on Twig templates. This makes the template system of Twig very powerful, and its auto-selection of templates based off of file name makes creating new templates and extending your theme a snap. If needed, further templates can be created for individual pages, such as if you want a specific template for a content type, a certain ID of a content type, and if a piece of a certain content type is the front page of your Drupal site. If the theme you created is a sub-theme, you probably have this file already that was inherited from the parent theme. This file is the most basic building block of your theme, and all other pieces start from there. Once your theme is set up, you need to create a base template file to use, which is called Īnd should go in a directory called templates Once it's created, it will appear in a custom themes directory for the Drupal installation you've created (/themes/custom/your_theme_here).

Overriding this way basically neglects those settings and renders in active language.Īpart from this method, there is also another way of doing it, which is just via preprocessing, but this might become complicated, as we will have to send array of translated results / rows of view separately: This will do the job for you, but as recommended we should override twigs in a manner that we make use of Drupal Views way of getting entity field values which are translated based on what you configure in your views, if you remember views allow you to configure rendering language of current row. #1 Use preprocess to add current language function MYTHEME_preprocess_views_view(&$vars) And there are various ways of getting the current language in the : For details check this: EntityField::getValueīut if somehow we wanna get translated version of the entity in a views twig, we will have to get the current language and then call ContentEntityBase::getTranslation on the entity of the views row. Though ideally if we use the views correctly and override them well, Drupal Views itself take care of getting the translated version as per configurations of the view.
