Flexslider 与背景图像响应

【中文标题】Flexslider 与背景图像响应

【英文标题】：Flexslider with background image responsive

【发布时间】：2014-07-16 06:19:21

【问题描述】：

我正在使用带有内容的 flexslider。所以我使用图像作为背景图像li 并将内容放在li 中。但如果我这样做，滑块就会失去响应式设计。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>

JS

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

@media (min-width: 2000px)

    height: auto;
  

对此有什么想法吗？

【参考方案1】：

SOLUTION

我正在使用 padding-top 来正确调整高度...

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

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