/* Stretching all container's parents to full height */

html,body {
  height: 100%;
  margin: 0;
  padding: 0;

/* All sections (container's children) should be table rows with minimal height */

.section {

.columns-container {

  margin: 0 auto;
}

.column {
  /* The float:left won't work for Chrome for some reason,so inline-block */
  display: inline-block;
  /* for this to work,the .column elements should have NO SPACE BETWEEN THEM */
  vertical-align: top;
  height: 100%;
  width: 100px;
}

  <div class="section expand">

        <p>Contents A</p>
      </div>
      <div class="column" id="b">

      </div>
    </div>
  </div>

  <footer class="section">
    bar
  </footer>
</div>

解决方法

如果在.columns-container的声明中添加text-align:center,则它们将集中对齐:
.columns-container {
    display: table-cell;
    height: 100%;
    width:600px;
    text-align: center;
}

.columns-container {

.column {

  vertical-align: top;
  height: 100%;
  width: 100px;
}

header {
  background-color: yellow;
}
#a {
  background-color: pink;
}
#b {
  background-color: lightgreen;
}
#c {
  background-color: lightblue;
}
footer {
  background-color: purple;
}
<div id="container">
  <header class="section">
    foo
  </header>

  <div class="section expand">
    <div class="columns-container">
      <div class="column" id="a">
        <p>Contents A</p>
      </div>
      <div class="column" id="b">
        <p>Contents B</p>
      </div>
      <div class="column" id="c">
        <p>Contents C</p>
      </div>
    </div>
  </div>

  <footer class="section">
    bar
  </footer>
</div>

但是,这样做需要将.column元素重置为text-align:left(假设您希望它们左对齐,显然(JS Fiddle demo).
