The core Layout Discovery module allows modules and themes to register layouts, and the core Layout Builder module provides a visual interface for placing fields and blocks in layouts for entity sub-types and individual entity items (see {{ content_structure_topic }} for more on entities and fields).{% endtrans %}</p>
 <h2>{% trans %}Changing site appearance overview{% endtrans %}</h2>
-<p>{% trans %}The main way to change the overall appearance of your site is to switch the default theme. You can also change the color palette of some themes, if the core Color module is installed and the theme supports it; some themes also have other settings. The core Layout Builder and Layout Discovery modules allow you to define layouts for your site's content, and the core Breakpoint module helps themes change appearance for different-sized devices.
