This is the first item's accordion body. It is shown by default, until the
                      collapse
                      plugin adds the appropriate classes that we use to style each element. These classes control the
                      overall
                      appearance, as well as the showing and hiding via CSS transitions. You can modify any of this
                      with
                      custom CSS or overriding our default variables. It's also worth noting that just about any HTML
                      can go
                      within the, though the transition does limit overflow.
