使 Materialise 滑块响应

Question

我正在尝试使用 CSS 使 Materialize 滑块响应，但它无法正常工作。当我使用 Firefox 的自适应视图测试我的代码时，我得到的滑块图像响应的灰色背景比滑块图像的高度大得多（如下所示）。

   .slider .slides li img {

background-size: 100% auto;;
background-repeat: no-repeat;
}

<div class="row">
<div class="slider " >
  <ul class="slides ">
                <li>
      <img class="responsive-img" id="img" src="{{ asset('font/images/IMG_61.jpg') }}"> 
    </li>
      <li>
      <img class="responsive-img" id="img" src="{{ asset('font/images/IMG_53.jpg') }}"> 
    </li>
    <li>
      <img class="responsive-img" id="img" src="{{ asset('font/images/IMG_2.jpg') }}"> 
    </li>
  </ul>
</div>
</div>

screen shot size 360×640

Answer 1

试试这个，对我有用

 .slider .slides {
    background-color: transparent;
    margin: 0;
    height: 400px;
}

.slider .slides li img {
    height: 100%;
    width: 100%;
    background-position: center;
    background-size:100% auto;
    background-repeat: no-repeat;
}

你确实有添加：

.fullscreen

到滑块，这可以工作，如文档中所示。耐心阅读人，仅此而已:)

Codepen 显示标记和初始化：

<div class="slider fullscreen">
  <ul class="slides">
    <li class="active" style="opacity: 1; transform: translateX(0px) translateY(0px);">
      <img src="data:image/gif;base64,R0lGODlhAQABAIABAP///wAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" style="background-image: url(&quot;https://images.unsplash.com/photo-1464817739973-0128fe77aaa1?dpr=1&amp;auto=compress,format&amp;fit=crop&amp;w=1199&amp;h=799&amp;q=80&amp;cs=tinysrgb&amp;crop=&quot;);"> <!-- random image -->

这是对我有用的解决方案： 中小型设备手动分配滑块高度为 250px，大型设备（宽度超过 600px 的设备）为 600px 滑块高度

 @media only screen and (max-width: 600px) {
          .slides {
            height: 250px !important;
          }
            .slider {
                 height: 250px !important;
            }
        }

@media only screen and (min-width: 600px) {
          .slides {
            height: 600px !important;
          }
            .slider {
                 height: 600px !important;
            }
        }
