html - 使段落高度 100%

Question

我想将段落的高度设置为 100%，但是当我尝试时它并没有这样做。以像素为单位设置大小确实有效。我有什么:

*,
html,
body {
  margin: 0;
  padding: 0;
  height: 100%;
  list-style: none;
}

.infoDiv {
  height: 50%;
  background: grey;
  background-size: cover;
  opacity: 0.6;
}

.textStart p {
  height: 100%;
  display: table-cell;
  vertical-align: middle;
}

<div class="infoDiv">
  <div class="imgStart col-xs-12 col-sm-7"></div>
  <div class="textStart col-xs-12 col-sm-5">
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure
      dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
  </div>
</div>

编辑:解决方案是为其提供 ViewHeight (vh)。

Answer 1

这是工作代码

*,
html,
body {
  margin: 0;
  padding: 0;
  height: 100%;
  list-style: none;
}

.infoDiv {
  height: 50%;
  background: grey;
  background-size: cover;
  opacity: 0.6;
}

.textStart p {
  height: 100vh;
  display: table-cell;
  vertical-align: middle;
}

<div class="infoDiv">
  <div class="imgStart col-xs-12 col-sm-7"></div>

  <div class="textStart col-xs-12 col-sm-5">
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure
      dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
  </div>
