在Bootstrap中相对定位100％的高度div

Question

I'm trying to make a sidebar on the left hand side of the page with the content to the right of it. the problem I'm running into is that when I try to make the div 100% height, I have to set it to position: absolute; which causes the content to overlap the sidebar.

Here is my 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>

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

And my 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;
}

Can anybody tell me how to make the div relative and 100% height or a better way to go about creating a sidebar?

Solution:

Add a height of 100vh (which is a length unit representing 1% of the viewport height). This will result in a sidebar that has a height of 100% of the viewport height. Also make sure you have your row(s) inside a .container or .container-fluid when you are using Twitter Bootstrap (if you didn't do that already).

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>

          </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;
}
