我正在使用 Django 开发电子商务网站，并在sby.delhinerds.com上展开。在此页面上：http://sby.delhinerds.com/products/shirts-1/，我需要一个多步骤表单，用户可以选择他/她的自定义并继续进行进一步的自定义。
虽然，图像选择和下一个按钮工作正常但是当我点击“上一个按钮”时， CSS 或 Javascript 改变和设计休息。我一直试图让它正常工作，但没有运气。请帮忙。
感谢。
如何重现错误的步骤：
1.转到http://sby.delhinerds.com/products/shirts-1/
2.单击任何图像并将其选中
3.单击下一个
4.在下一步中，单击上一步，CSS或JS将彻底更改。
我的HTML，CSS和Javascript / jQuery是
$('.images_list li').click(function() {
$('.images_list .selected').removeClass('selected');
$(this).toggleClass('selected');
var clicked = $(this).attr('title');
$("#"+clicked).removeClass("hidden").siblings().addClass("hidden");

var current_fs, next_fs, previous_fs; //fieldsets
var left, opacity, scale; //fieldset properties which we will animate
var animating; //flag to prevent quick multi-click glitches
$(".next").click(function(){

animating = true;
current_fs = $(this).parent();
next_fs = $(this).parent().next();
//activate next step on progressbar using the index of next_fs
$("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

//hide the current fieldset with style
current_fs.animate({opacity: 0}, {

答案 0 :(得分：0)
为此属性position:relative
previous_fs.css({'transform': 'scale('+scale+')', 'position':'relative','opacity': opacity});
答案 1 :(得分：0)
在'position':'relative'
previous_fs.css({'transform': 'scale('+scale+')', 'opacity': opacity});
结果将是
previous_fs.css({'transform': 'scale('+scale+')','position':'relative', 'opacity': opacity});
