Block Kit is made up of many atomic building blocks.

Blocks are visual components that can be arranged to create app layouts. Apps can add blocks to surfaces like App Home, messages and modals.

Blocks may also contain block elements. Block elements are usually interactive components, such as buttons and menus.

Blocks and block elements are built with composition objects. Composition objects define text, options, or other interactive features within certain blocks and block elements.
