Use accordions to organize and minimize content that needs to be in a section, but does not need to be displayed on page load. This gives the viewer an opportunity to view the headings before digging into expanded content.
Content is organized into folds and each fold is closed as a default. The user chooses whether or not to open a fold. An accordion can have multiple folds and can only be used in a 100% column layout. Each fold must contain content to be visible once published.
