php - 无法在图像容器中制作白色背景

Question

我需要帮助在边框内制作白色以及黑色描述。

实际场景位于此处:http://buyersstop.blogspot.in/2016/01/motoe.html

我的问题是，如果我应用白色背景颜色，图像周围会出现黑色边框。

div.img1 {
  border: 1px solid #777;
}
div.img1:hover {
  border: 1px solid #ccc;
}
div.img1 img {
  width: 100%;
  height: auto;
}
div.desc {
  padding: 15px;
  text-align: center;
}
* {
  box-sizing: border-box;
}
.responsive {
  padding: 6px 6px;
  float: left;
  width: 32.99999%;
}
@media only screen and (max-width: 700px) {
  .responsive {
    width: 49.99999%;
    margin: 6px 0;
  }
}

<div class="responsive">
  <div class="img1">
    <a target="_blank" href="img_fjords.jpg">
      <img src="http://ecx.images-amazon.com/images/I/71YgvTPQnKL._SL1500_.jpg" alt="Trolltunga Norway" width="600" height="400">
    </a>

我对您的代码做了一些修改，请参阅我的更新代码。希望和你想象的一样。

div.img1 {
  border: 1px solid #777;
}
div.img1:hover {
  border: 1px solid #ccc;
}
div.img1 img {
  width: 100%;
  height: auto;
}
div.desc {
    padding: 15px;
    text-align: center;
    position: absolute;
    bottom: 7px;
    color: #fff;
    left: 6px;
    width: 96%;
    background-color: rgba(10,10,10,0.5);
}
* {
  box-sizing: border-box;
}
.responsive {
  padding: 6px 6px;
  float: left;
  width: 32.99999%;
  position:relative;
  background-color:#fff;
}
@media only screen and (max-width: 700px) {
  .responsive {
    width: 49.99999%;
    margin: 6px 0;
  }
