The Breakpoint module provides a method to create media query breakpoint definitions within Drupal. These can be used by other components, such as the responsive image and toolbar modules, to make Drupal responsive.
Breakpoints are a type of plugin that can be defined in a module's or theme's breakpoints.yml in its directory. In this recipe, we will define three different breakpoints under a custom group.
Breakpoints are defined solely in YAML files from installed modules and themes and are not configurable through the user interface.
