在DIV内拉伸DIV到100％高度？

Question

我想将div内的DIV-Container拉伸到100％的高度。我想要拉伸的DIV-Container在里面有一个图像

<img src="http://thisisatestforstack.com/image.png"/>

我还想在之后垂直居中。我准备了一张让我的愿望更清晰的照片：

这是我的代码：

<div id="master">
    <div id="text" style="width: 60%; float: left;">
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.<br/>
        This is an example.
    </div>

    <div id="image" style="width: 40%; float: left;">
        <img src="http://thisisatestforstack.com/image.png"/>
    </div>
</div>

使用flexbox布局，您可以实现：

代码段

#master {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-align: center;
  -webkit-align-items: center;
  -ms-flex-align: center;
  align-items: center;
  -webkit-box-pack: center;
  -webkit-justify-content: center;
  -ms-flex-pack: center;
  justify-content: center;
}
#text {
  -webkit-box-flex: 1;
  -webkit-flex: 1;
  -ms-flex: 1;
  flex: 1;
}
#image {
  -webkit-box-flex: 1;
  -webkit-flex: 1;
  -ms-flex: 1;
  flex: 1;
}
.item-top {
  width: 60%;
  float: left;
  -webkit-align-self: flex-start;
  -ms-flex-item-align: start;
  align-self: flex-start;
}

<div id="master">
  <div id="text" class="item-top">
    This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
    <br/>This is an example.
  </div>

  <div id="image" style="width: 40%; float: left;">
    <img src="https://www.google.co.in/logos/doodles/2016/teachers-day-2016-india-6215218130583552-res.png" />
  </div>
</div>
