html - 在 Bootstrap 中制作一个相对定位的 100% 高度的 div

Question

我正在尝试在页面左侧创建一个侧边栏，内容位于右侧。我遇到的问题是，当我尝试将 div 设置为 100% 高度时，我必须将其设置为 position: absolute;这会导致内容与侧边栏重叠。

这是我的 HTML

<div class="row">
  <div class="sidebar col-sm-3">
    <ul>
      <li class="active">
        <h3><a href="">Link</a></h3>
      </li>
      <li class="">
        <h3><a href="">Link</a></h3>
      </li>
      <li class="">
        <h3><a href="">Link</a></h3>
      </li>
      <li class="active">
        <h3><a href="">Link</a></h3>
      </li>
    </ul>
  </div>
  <!-- sidebar -->
  <div class="sidebar-content col-sm-9">
    <ul>
      <li class="active">
        <h2 class="underline">Link</h2>
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rerum nostrum assumenda sequi praesentium aperiam. Accusamus omnis velit quos sint quas corporis inventore, facilis laborum pariatur explicabo maxime voluptas at aliquid!</p>
      </li>
      <li class="">
        <h2 class="underline">Link</h2>

      </li>
      <li class="">
        <h2 class="underline">Link</h2>

      </li>
      <li class="">
        <h2 class="underline">Link</h2>

      </li>
    </ul>
  </div>
  <!-- sidebar-content -->
</div>
<!-- row -->

还有我的 CSS

.sidebar {
background: #eee;
height: 100%;
padding-top: 100px !important;
}

.sidebar-content ul li {
display: none;
}

.sidebar-content ul li.active {
display: block;
}

.sidebar-content {
position: relative;
right: 0;
padding: 100px;
}

谁能告诉我如何使 div 相对和 100% 高度或更好的方法来创建侧边栏？

解决方案:

添加 100vh 的 height(这是一个长度单位，代表视口(viewport)高度的 1%)。这将导致侧边栏的 height 为视口(viewport)高度的 100%。当您使用 Twitter Bootstrap 时，还要确保您的行位于 .container 或 .container-fluid 中(如果您还没有这样做的话)。

HTML:

<div class="container-fluid">
    <div class="row">
      <div class="sidebar col-sm-3">
        <ul>
          <li class="active">
            <h3><a href="">Link</a></h3>
          </li>
          <li class="">
            <h3><a href="">Link</a></h3>
          </li>
          <li class="">
            <h3><a href="">Link</a></h3>
          </li>
          <li class="active">
            <h3><a href="">Link</a></h3>
          </li>
        </ul>
      </div><!-- sidebar -->
      <div class="sidebar-content col-sm-9">
        <ul>
          <li class="active">
            <h2 class="underline">Link</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rerum nostrum assumenda sequi praesentium aperiam. Accusamus omnis velit quos sint quas corporis inventore, facilis laborum pariatur explicabo maxime voluptas at aliquid!</p>
          </li>
          <li class="">
            <h2 class="underline">Link</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rerum nostrum assumenda sequi praesentium aperiam. Accusamus omnis velit quos sint quas corporis inventore, facilis laborum pariatur explicabo maxime voluptas at aliquid!</p>
          </li>
          <li class="">
            <h2 class="underline">Link</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rerum nostrum assumenda sequi praesentium aperiam. Accusamus omnis velit quos sint quas corporis inventore, facilis laborum pariatur explicabo maxime voluptas at aliquid!</p>
          </li>
          <li class="">
            <h2 class="underline">Link</h2>

          </li>
        </ul>
      </div><!-- sidebar-content -->
  </div><!-- row -->
</div>

CSS:

.sidebar {
  background: #eee;
  height: 100vh;
  padding-top: 100px;  
}

.sidebar-content ul li {
  display: none;
}

.sidebar-content ul li.active {
  display: block;
}

.sidebar-content {
  padding: 100px;
  position: relative;
  right: 0;
}
