responsiveSlides.js似乎没有正确设置css

Question

我无法使用responseSlides.js来工作。这是我在jsfiddle中的尝试

https://jsfiddle.net/w2nPP/9/

我忘了什么吗？

$(document).ready(function() {
var settings = {auto: true,            
                          speed: 500,            
                          timeout: 4000,         
                          pager: true,          
                          nav: true,            
                          random: false,          
                          pause: false,           
                          pauseControls: true,    
                          prevText: "Previous",  
                          nextText: "Next",      
                          maxwidth: "",           
                          navContainer: "",      
                          manualControls: "",    
                          namespace: "rslides",   
                          before: function(){},   
                          after: function(){}     
                        }
$(function() {
    $('.rslides').responsiveSlides(settings);
});
});
