In Twenty Twenty-One, block patterns are defined in inc/block-patterns.php file. Twenty Twenty-One patterns vary from simple patterns like the Large Text pattern, which contains a single H2 element, to more complex patterns, such as Overlapping Images and Text and Media and Text Article Title.

Currently, the theme provides the following patterns:

* Links Area: A huge text followed by social networks and email address links.

* Media and Text Article Title: A Media & Text block with a big image on the left and a heading on the right. The heading is followed by a separator and a description paragraph.
