我创建了一个图片幻灯片，如下所示：

＆＃13;
＆＃13; 
jQuery(document).ready(function($) {

  $('#checkbox').change(function() {
    setInterval(function() {
      moveRight();
    }, 3000);
  });

  var slideCount = $('#slider ul li').length;
  var slideWidth = $('#slider ul li').width();
  var slideHeight = $('#slider ul li').height();
  var sliderUlWidth = slideCount * slideWidth;

  $('#slider').css({
    width: slideWidth,
    height: slideHeight
  });

  $('#slider ul').css({
    width: sliderUlWidth,
    marginLeft: -slideWidth
  });

  $('#slider ul li:last-child').prependTo('#slider ul');

  function moveLeft() {
    $('#slider ul').animate({
      left: +slideWidth
    }, 200, function() {
      $('#slider ul li:last-child').prependTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  function moveRight() {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  $('a.control_prev').click(function() {
    moveLeft();
  });

  $('a.control_next').click(function() {
    moveRight();
  });

});
＆＃13;

我想重新安排图片如下： enter image description here

我已尝试将更多图像包含在内，图像最终出现故障并且无法正常工作我也尝试缩小尺寸，但如果有人有任何指示或想法，它们仍然会出现在不同的视图中，请告诉我。

如果你能告诉我如何修改它，那就太棒了我不介意如果它在JS或CSS中，只要它完成工作我会非常感激。

如果这个问题需要改进，那么只是试图告诉我而不仅仅是贬低我不会伤害我只有13年而且还在提前学习谢谢。

我在javascript和css上做了一些更改，特别是在宽度和高度上。

jQuery(document).ready(function($) {

  $('#checkbox').change(function() {
    setInterval(function() {
      moveRight();
    }, 3000);
  });

  var slideCount = $('#slider ul li').length;
  var slideWidth = $('#slider ul li').width();
  var sliderUlWidth = slideCount * slideWidth;

  $('#slider').css({
    width: parseInt(slideWidth) * 3 +"px",
  });

  $('#slider ul').css({
    width: sliderUlWidth
  });

  $('#slider ul li:last-child').prependTo('#slider ul');

  function moveLeft() {
    $('#slider ul').animate({
      left: +slideWidth
    }, 200, function() {
      $('#slider ul li:last-child').prependTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  function moveRight() {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  $('a.control_prev').click(function() {
    moveLeft();
  });

  $('a.control_next').click(function() {
    moveRight();
  });

});
