我正在使用这种幻灯片格式在 eBay 商品列表上显示横幅。我希望将幻灯片链接到商店中的各个页面，但是我尝试以传统方式添加超链接（请参阅“img_02”）并且绝对没有运气使幻灯片可点击。我在这里看到了类似的问题，并尝试了一些不同的“工作”解决方案，但没有任何运气。如果有人能就如何解决这个问题提出建议，将不胜感激。

Answer 1

似乎是一个 z-index 问题，而且因为您绝对定位您的图像，您的链接将没有高度。

在下面，我将您的图像包装在跨度中并定位它而不是图像（与锚具有相同的类，因此也可以定位）并向您的动画添加一些 z-index（代码中的 cmets）。

.zd-slider {
  position: relative;
  overflow: hidden;
  margin-top: 0px;
}

.zd-slider .container { /* move this from image to new container span / link */
  display: block;
  width: 100%;
  position: absolute;
  left: 0;
  top: 0;
  opacity: 0;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
}

.zd-slider img {
  display: block;
  width: 100%;
}


/* set the width/height of the slideshow */

.zd-slider #blank {
  visibility: hidden;
  pointer-events: none; /* I added this in case it appeared on top of the absolute positioned elements - it shouldn't but just to be safe */
}


/* the slideshow */

.zd-slider #img_01 {
  -webkit-animation: autoplay 9s linear infinite 0s;
  animation: autoplay 9s linear infinite 0s;
}

.zd-slider #img_02 {
  -webkit-animation: autoplay 9s linear infinite 3s;
  animation: autoplay 9s linear infinite 3s;
}

.zd-slider #img_03 {
  -webkit-animation: autoplay 9s linear infinite 6s;
  animation: autoplay 9s linear infinite 6s;
}

@-webkit-keyframes autoplay {
  4%,
  33% {
    opacity: 1;
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
    z-index: 2; /* add this to make sure visible item has a higher z-index that none visible items */
  }
  0%,
  37%,
  100% {
    opacity: 0;
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
    z-index: 1; /* add this to make sure visible item has a higher z-index that none visible items */
  }
}

@keyframes autoplay {
  4%,
  33% {
    opacity: 1;
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
    z-index: 2; /* add this to make sure visible item has a higher z-index that none visible items */
  }
  0%,
  37%,
  100% {
    opacity: 0;
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
    ] z-index: 1; /* add this to make sure visible item has a higher z-index that none visible items */
  }
}

  -webkit-animation: slide 3s linear infinite;

  z-index: 3; /* make slider appear above images */
}

@keyframes slide {

Answer 2

尝试添加以下 css 属性

.zd-slider a { display: inline-block; }

因为a标签没有得到任何宽度或高度，可能无法正确解释你，试试这个，肯定会工作。

Answer 3

问题来自您的position: absolute。

它从正常流程中删除所有图像。所以<a/> 标签不会“包含”图像。

您可以尝试使用静态位置和 transform: translate 动画而不是 opacity，这样就不需要堆叠图像。

Answer 4

这行得通，需要将位置、宽度、高度和z-index都应用到链接上：

   #img_02_link{
     position: absolute; 
     top:0; left:0; 
     width: 100%; 
     height: 100%; 
     z-index:1;
  }

    .zd-slider { position:relative; overflow:hidden; margin-top: 0px; }
    .zd-slider img[id*="img"] {width:100%; position:absolute; left:0; top:0; opacity:0; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";}

    /* set the width/height of the slideshow */
    .zd-slider img#blank {display:block; width:100%; visibility:hidden;}

    /* the slideshow */
    .zd-slider #img_01 {-webkit-animation:autoplay 9s linear infinite 0s; animation:autoplay 9s linear infinite 0s;}
    .zd-slider #img_02 {-webkit-animation:autoplay 9s linear infinite 3s; animation:autoplay 9s linear infinite 3s;}
    .zd-slider #img_03 {-webkit-animation:autoplay 9s linear infinite 6s; animation:autoplay 9s linear infinite 6s; }


    @-webkit-keyframes autoplay {
      4%,33% {opacity:1;-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";}
      0%,37%,100% {opacity:0;-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";}
    }


    @keyframes autoplay {
      4%,33% {opacity:1;-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";}
      0%,37%,100% {opacity:0;-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";}
    }

    /* the slide timing indicator */
    .zd-slider #slide {width:98px; height:5px; position:absolute; left:0; bottom:0; background:rgba(255,255,255,0.5); 
    -webkit-animation:slide 3s linear infinite; animation:slide linear 3s infinite;}

    @keyframes slide {
      0% {left:-100px;}
      100% {left:100%;}
    }
    @-webkit-keyframes slide {
      0% {left:-100px;}
      100% {left:100%;}
    }

Answer 5

为每个滑块图像创建一个单独的 div，并将 Z-index 赋予该公共类 div....
