Twig Attributes allows developers to set HTML attributes (such as classes or an id) in a parent Twig template to elements in a child template, eliminating the need to create a template override or implement a preprocess hook just to add an attribute. It is particularly useful when working with fields that do not by default support attributes on certain HTML elements, such as links. Twig Attributes includes specific support for a number of templates provided by Drupal core, including ones used for image fields, responsive image fields, and links.
