Full width section block configuration
By default, all page content has width restrictions set in theme settings. To stretch the content beyond the main wrapper and set it to the full width of the screen, the Full width section block is used. After adding the block to the page, you’ll have a choice between blocks that will wrap the content of the section. This can be a Row, Container, or Blank.
Rows or Containers will help limit the content width according to the global site wrapper. The width of the Row or Container inside the Full width content section can be further adjusted using the Width option found in the Advanced tab.
Using the last option, Blank, you can directly add content blocks to the section, and they won’t be limited in width by any wrapper. It’s worth noting that the Full width content block is most suitable for use only in the root of the editor and in the absence of any sidebars on the page.
