页面的head部分，需引入页面的样式文件，代码如下：

<link type="text/css" rel="stylesheet" href="css/style.css">

页面的body部分，用了多个div的嵌套结构，不算很复杂，代码如下：

<div class="demo">
  <div class="demo__content">
    <h2 class="demo__heading">你喜欢什么样的页面布局呢？</h2>
    <div class="demo__elems">
      <div class="demo__elem demo__elem-1">简约的多文字布局</div>
      <div class="demo__elem demo__elem-2">一列的图文混排布局</div>
      <div class="demo__elem demo__elem-3">两列的图文混排布局</div>
      <span class="demo__hover demo__hover-1"></span>
      <span class="demo__hover demo__hover-2"></span>
      <span class="demo__hover demo__hover-3"></span>
      <div class="demo__highlighter">
        <div class="demo__elems">
          <div class="demo__elem">简约的多文字布局</div>
          <div class="demo__elem">一列的图文混排布局</div>
          <div class="demo__elem">两列的图文混排布局</div>
        </div>
      </div>
      <div class="demo__examples">
        <div class="demo__examples-nb">
          <div class="nb-inner">
            <div class="example example-adv">
              <div class="example-adv">

                <div class="example-web__right-line"></div>
              </div>
            </div>
            <div class="example example-both">

                <div class="example-both__right-mid"></div>
              </div>
            </div>
          </div>
        </div>
      </div>
