layout_bg-8.x-1.0/examples/layout_bg_bricks/layout_bg_bricks.layouts.yml

# See layout_discover.layout.yml.
# Compare to layout_twocol_bricks.
# Changes we made...
# 1. Use layout__layout_bg as thew theme_hook.
#    Remove the template key in favor of theme_hook.
#    We also remove the path key.
# 2. Add our very simple layout class as the class.
#    It is defined in this example module.
#    Note that the class sets 'layout--twocol-bricks.html.twig'
#    as the base template. That's the template declared in
#    layout_discover.layout.yml for layout_twocol_bricks.
# 3. Use the library defined in this example module as the library.
# 4. Add background to the list of regions.
