我试图实现一个看起来像这样的幻灯片

http://ge.tt/api/1/files/2AjKcVM/0/blob/x675?noinc=1

其中宽度为 100%，并保持向左或向右无限滚动，但无论浏览器分辨率如何，始终在中心有一个图像。这就是我到目前为止所得到的

http://fourcreeklandscape.com/index2.html

幻灯片图像的宽度为 800 像素，最左边的图像的左侧边距为 -25% ......看起来它在 1280 像素的屏幕尺寸下工作......但看起来不像我调整大小时的假设窗户。

这是我使用的幻灯片代码

$(document).ready(function() {
    //move he last list item before the first item. The purpose of this is if the user clicks to slide left he will be able to see the last item.
    $('#carousel_ul li:first').before($('#carousel_ul li:last')); 


    //when user clicks the image for sliding right        
    $('#right_scroll img').click(function(){

        //get the width of the items ( i like making the jquery part dynamic, so if you change the width in the css you won't have o change it here too ) '
        var item_width = $('#carousel_ul li').outerWidth() + 10;

        //calculae the new left indent of the unordered list
        var left_indent = parseInt($('#carousel_ul').css('left')) - item_width;

        //make the sliding effect using jquery's anumate function '
        $('#carousel_ul:not(:animated)').animate({'left' : left_indent},500,function(){    

            //get the first list item and put it after the last list item (that's how the infinite effects is made) '
            $('#carousel_ul li:last').after($('#carousel_ul li:first')); 

            //and get the left indent to the default -210px
            $('#carousel_ul').css({'left' : '-210px'});
        }); 
    });

    //when user clicks the image for sliding left
    $('#left_scroll img').click(function(){

        var item_width = $('#carousel_ul li').outerWidth() + 10;

        /* same as for sliding right except that it's current left indent + the item width (for the sliding right it's - item_width) */
        var left_indent = parseInt($('#carousel_ul').css('left')) + item_width;

        $('#carousel_ul:not(:animated)').animate({'left' : left_indent},500,function(){    

        /* when sliding to left we are moving the last item before the first list item */            
        $('#carousel_ul li:first').before($('#carousel_ul li:last')); 

        /* and again, when we make that change we are setting the left indent of our unordered list to the default -210px */
        $('#carousel_ul').css({'left' : '-210px'});
        });


    });});

有任何想法吗？谢谢

你可以把这个CSS放在#carousel_ul

left: 50%;
margin-left: -1200px;

只要确保它从左到右。唯一的问题是，如果有人的显示器宽度可能超过 2000 像素，当幻灯片第一次开始播放时，他们会在左边有点没有图像 - 但我认为这很少有人。
