<strong>This is the first item's accordion body.</strong> 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 <code>.accordion-body</code>, though the transition does limit
                            overflow.
