单击按钮显示和隐藏内容

Question

我正在尝试制作一个卡片滑块，以便在单击下一步按钮时，背景视频将显示在卡片的后面，每次单击下一步时，您会看到另一张卡片，而我会看到另一个背景视频我不确定该怎么做。

https://jsfiddle.net/t4tr56/jz8qeyL1/6/本质上是这样的：

$(document).ready(function () {
  var getslideHeight = $('.slide.active').height();

  $('.slides').css({
    height: getslideHeight
  });

  function calcslideHeight() {
    getslideHeight = $('.slide.active').height();

    $('.slides').css({
      height: getslideHeight
    });
  }

  function animateContentColor() {
    var getslideColor = $('.slide.active').attr('slide-color');

    $('body').css({
      background: getslideColor
    });

    $('.title').css({
      color: getslideColor
    });

    $('.btn').css({
      color: getslideColor
    });
  }

  var slideItem = $('.slide'),
    slideCurrentItem = slideItem.filter('.active');

  $('#next').on('click', function (e) {
    e.preventDefault();

    var nextItem = slideCurrentItem.next();

    slideCurrentItem.removeClass('active');

    if (nextItem.length) {

      slideCurrentItem = nextItem.addClass('active');
    } else {
      slideCurrentItem = slideItem.first().addClass('active');
    }

    calcslideHeight();
    animateContentColor();
  });

  $('#prev').on('click', function (e) {
    e.preventDefault();

    var prevItem = slideCurrentItem.prev();

    slideCurrentItem.removeClass('active');

    if (prevItem.length) {
      slideCurrentItem = prevItem.addClass('active');
    } else {
      slideCurrentItem = slideItem.last().addClass('active');
    }

    calcslideHeight();
    animateContentColor();
  });

  // Ripple
  $('[ripple]').on('click', function (e) {
    var rippleDiv = $('<div class="ripple" />'),
      rippleSize = 60,
      rippleOffset = $(this).offset(),
      rippleY = e.pageY - rippleOffset.top,
      rippleX = e.pageX - rippleOffset.left,
      ripple = $('.ripple');

    rippleDiv.css({
      top: rippleY - (rippleSize / 2),
      left: rippleX - (rippleSize / 2),
      background: $(this).attr("ripple-color")
    }).appendTo($(this));

    window.setTimeout(function () {
      rippleDiv.remove();
    }, 1900);
  });
});
