The Section element (available since 1.5) allows you to structure/divide your page into self-containing areas (think: one topic per section).
The Understanding the Layout article covers in more detail how to best use the layout elements in Bricks.
The Section element has a default width of 100%, uses the section tag, and flexbox.
It should be used at the root level to structure your page into self-containing areas.
When adding a Section to the canvas, a Container element is added inside of the Section automatically. You can delete this Container if not needed. It’s just the default behaviour to speed up your site creation process.
Theme Style: Element – Section
You can change the section width, min-width, max-width, margin, and padding in your theme styles under the “Element – Section” group.
