                </div>
            </div>
        </div>

    </div>

JS

$(function(){
    $('.fadein .slider:gt(0)').hide();

    setInterval(function(){
        $('.fadein :first-child').fadeOut().next('.slider').fadeIn().end().appendTo('.fadein');
    }, 3000);
});
$(function(){
    $('.fadeinSpan span:gt(0)').hide();
    setInterval(function(){
        $('.fadeinSpan :first-child').fadeOut().next('span').fadeIn().end().appendTo('.fadeinSpan');
    }, 3000);
});

When I try to do it for Javascript it only exchanges the images and what I would like is for it to change the container, that is, of that means a None display in the previous one and a display block in the next in a certain time.
