Jquery 具有背景图像响应功能的Flexslider

我正在使用flexslider和内容。因此，我将这些图像用作背景图像

li

，并将内容放在

li

中。但如果我这样做，滑块就会失去响应性设计。我使用了以下代码

Html

<div id="flexslider-container" class="flexslider-container">
<div class="flexslider">
  <ul class="slides">
<li style="background-image: url({{skin url='images/slider/slide1.jpg'}});">
      <a class="shopnow_btn" href="#">Shop Now</a>
    </li>
    <li style="background-image: url({{skin url='images/slider/slide1.jpg'}});">
      <a class="shopnow_btn" href="#">Shop Now</a>
    </li>
    <li style="background-image: url({{skin url='images/slider/slide1.jpg'}});">
      <a class="shopnow_btn" href="#">Shop Now</a>
    </li> 
</ul>
</div>
</div>

CSS

jQuery(window).load(function($) {
jQuery('.flexslider').flexslider({
    animation: "slide",
      controlNav: true,
      directionNav: true
});
});

@media (min-width: 2000px) {
  img{
    height: auto;
  }
}

有什么想法吗？

我正在使用填充顶部来正确调整高度

请注意，flexslider将ul宽度设置为1000%。。。这使得计算填充变得容易。我使用的是350 x 250的图像

.flexslider div li {
  background-size: cover;
  padding-top: 6.57%; 
}
