# What makes up the main storefront layout?

By default, all of your pages reference your 'main' layout - this ensures the same scaffolding structure for each of your sections/pages

The 'main' layout calls divides your page into the following screen areas:

- **header**calls the 'header' section - **breadcrumb**calls the 'breadcrumb' section - **footer**calls the 'footer' section - **cookie bar**calls the 'cookie-bar' section - **content**points back to the page (twig file) from which layout was called. 

The main layout uses Aero Sections
