仅在HTML和CSS中使用自动缩放的图像网格

Question

我一直在尝试制作响应式自动重新缩放图像网格，以便在我们的网站上展示广告。我用它作为参考 - W3Schools-ImageGridMaker

基于此，我尝试了4天来提出这段代码。

div.gallery {
  border: 1px solid #ccc;
}

div.gallery:hover {
  border: 1px solid #777;
}

div.gallery img {
  display: block;
  object-fit: contain;
  max-width: 100%;
  max-height: 100%;
  width: auto;
  height: auto;
}

div.desc {
  padding: 15px;
  text-align: center;
}

* {
  box-sizing: border-box;
}

.responsive {
  padding: 0 6px;
  float: left;
  width: 24.99999%;
}

@media only screen and (max-width: 700px) {
  .responsive {
    width: 49.99999%;
    margin: 6px 0;
  }
}

@media only screen and (max-width: 500px) {
  .responsive {
    width: 100%;
  }
}

.clearfix:after {
  content: "";
  display: table;
  clear: both;
}

div.boxed {
  border: 5px solid red;
  width: 100%;
  height: auto;
  overflow: auto;
}

<div class="boxed">

  <div class="responsive">
    <div class="gallery">
      <a target="_blank" href="https://tnilive.com" onclick="window.open('https://www.google.com'); window.open('https://www.yahoo.com');"> <img src="https://i.imgur.com/UgPbxk2.jpg" alt="Shiva1"></a>

  <div class="responsive">
    <div class="gallery">
      <a target="_blank" href="https://tnilive.com" onclick="window.open('https://www.google.com'); window.open('https://www.yahoo.com');"> <img src="https://i.imgur.com/ColLeDr.png" alt="Shiva2"></a>

  <div class="responsive">
    <div class="gallery">
      <a target="_blank" href="https://tnilive.com" onclick="window.open('https://www.google.com'); window.open('https://www.yahoo.com');"> <img src="https://i.imgur.com/gVjcLg2.jpg" alt="Shiva3"></a>

  <div class="responsive">
    <div class="gallery">
      <a target="_blank" href="https://tnilive.com" onclick="window.open('https://www.google.com'); window.open('https://www.yahoo.com');"> <img src="https://i.imgur.com/nxGxovl.png" alt="Shiva4"></a>
    </div>
  </div>

</div>

这段代码是响应性的，在手机上我没有问题，因为它看起来很整洁，填满整个区域。但是如果你在桌面上看它，它会在一些不适合高度的图片下面注入空白空间。我正在使用大量的URL并可以将它们作为列表提供，以便桌面上的这个1280X200px区域填充整齐的不同大小的图像。我试着查看freewall和其他大量的jsfiddles和笔但是无法实现如何移除空白并使特定的盒子看起来很好。谢谢。

根据我的评论 - 我会使用一个使用对象适合的flexbox解决方案（使用polyfil作为ie）：

.container {
  display: flex;
  flex-direction: row;   /* default value so optional - lines children in a row */
  flex-wrap: wrap;        /* allows children to wrap */
  justify-content: space-between; /* space children evenly over row */
}

.responsive {
  flex-basis: 25%;  /* makes the width 25% */
  
  /* if you don't want a fixed height image, I would use the padding top trick for aspect ratio divs */
  position: relative;
  padding-top: 30%;
}

.responsive img {
  position:absolute;
  display: block;
  width: 100%;
  height: 100%;
  top:0;
  left:0;
  object-fit:cover;
}


@media only screen and (max-width: 700px) {
  .responsive {
    flex-basis: 50%;
    margin: 6px 0;
  }
}

@media only screen and (max-width: 500px) {
  .responsive {
    flex-basis: 100%;
    padding-top: 50%;
  }
}
