In the main container, all elements of your layout are combined. In the
layout structure, you will find below the entry for Main
container all elements are contained in the hierarchy in which you currently see on
the workspace. Here as well you have direct access to the HTML
properties via the Element Settings area.
Here you will find the ID of the container and you
can edit the Title. You can define a Heading
Level and enter a Heading. The Heading
Level will not influence the structure of the layout, but it
will be, like the Heading itself, written in HTML below the container
and can be used from screen readers and search engines.If
you wish to construct barrier-free pages, or simply bring more
transparency to your layout construction, you can assign the element a role here.
