【问题描述】：

今天，我正在尝试制作简单的作品集。我为 Bootstrap 找到了this template。它看起来很漂亮，但是当我添加一些其他照片时，它开始产生空白：

有没有办法把这张照片上移，这样就没有空格了？

css:

body {
    background-color: #434c50;
    min-height: 100vh;
    font: normal 16px sans-serif;
    padding: 40px 0;
}

.container.gallery-container {
    background-color: #fff;
    color: #35373a;
    min-height: 100vh;
    padding: 30px 50px;
}

.gallery-container h1 {
    text-align: center;
    margin-top: 50px;
    font-family: 'Droid Sans', sans-serif;
    font-weight: bold;
}

.gallery-container p.page-description {
    text-align: center;
    margin: 25px auto;
    font-size: 18px;
    color: #999;
}

.tz-gallery {
    padding: 40px;
}

/* Override bootstrap column paddings */
.tz-gallery .row > div {
    padding: 2px;
}

.tz-gallery .lightbox img {
    width: 100%;
    border-radius: 0;
    position: relative;
}

.tz-gallery .lightbox:before {
    position: absolute;
    top: 50%;
    left: 50%;
    margin-top: -13px;
    margin-left: -13px;
    opacity: 0;
    color: #fff;
    font-size: 26px;
    font-family: 'Glyphicons Halflings';
    content: '\e003';
    pointer-events: none;
    z-index: 9000;
    transition: 0.4s;
}


.tz-gallery .lightbox:after {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    opacity: 0;
    background-color: rgba(217, 217, 217, 0.5);
    content: '';
    transition: 0.4s;
}

.tz-gallery .lightbox:hover:after,
.tz-gallery .lightbox:hover:before {
    opacity: 1;
}

.baguetteBox-button {
    background-color: transparent !important;
}

@media(max-width: 768px) {
    body {
        padding: 0;
    }
}

.menu {
  color: #999 !important;
  text-align: right;
}

【解决方案1】：

不幸的是，布局依赖于图像要么是设定的高度，要么是设定高度的两倍。一旦您开始输入不是 1:1 或 2:1 高度的图像，就会出现间隙。您可以切换到一列而不是行布局，但是您将失去让一个项目跨越两列的能力。

如果您受制于这种特定的布局，也许您可以拥有适合 1:1、1:2、2:1 和 2:2 模式的图像裁剪版本，并且这些裁剪版本可以用作链接到完整的未裁剪版本的缩略图。

【解决方案2】：

一个简单的解决方案是将标记更改为三个列，并且在每个列中都有一个图像列表，例如：

<div class="tz-gallery">
  <div class="row">
     <div class="col-sm-6 col-md-4">
       <div class="col-md-12">
          <a class="lightbox" href="../images/park.jpg">
              <img src="../images/park.jpg" alt="Park">
          </a>
       </div>
     </div>
     <div class="col-sm-6 col-md-4">
        <div class="col-md-12">
          <a class="lightbox" href="../images/park.jpg">
              <img src="../images/park.jpg" alt="Park">
          </a>
        </div>
        <div class="col-md-12">
          <a class="lightbox" href="image.jpg">
                <img src="image.jpg" alt="Bridge">
          </a>
        </div>
     </div>         
     <div class="col-sm-6 col-md-4">
        <div class="col-md-12">
          <a class="lightbox" href="../images/park.jpg">
              <img src="../images/park.jpg" alt="Park">
          </a>
         </div>
     </div>
  </div>
</div>

那么文档就可以正确渲染每列的每个图像
