Building with sections and blocks

When you're designing a theme, you should consider when to provide functionality in a section or a block. Sections and blocks are modular components that give merchants the opportunity to customize and extend their theme. Merchants can add and remove sections and theme blocks, adjust section and block settings, and introduce app blocks and metafields.

These guidelines apply to Online Store 2.0 themes, which use JSON templates and section groups. You can't add or remove static sections from Liquid templates or layouts.
