CSS实例讲解:地图提示（2）

首先我们要显示5部分内容，内容结构相似，我们可以选用无序列表来显示介绍的图片和内容：

<ul>
  <li><a id="map01" href="#map01"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111743602.jpg" alt="Post Office" />This is the Popsville community <strong>Post Office</strong>, your home of over-priced postage. Click map for more</a></li>
  <li><a id="map02" href="#map02"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111743990.jpg" alt="Dew Drop Inn" />Home is where the beer is. And that means the <strong>Dew Drop Inn</strong>. Live music on the weekends. Click map for more</a></li>
  <li><a id="map03" href="#map03"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744507.jpg" alt="River Beach" />Spend lazy summer afternoons at the beautiful <strong>River Beach</strong>. Hang out on the nude beach. Click map for more</a></li>
  <li><a id="map04" href="#map04"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744638.jpg" alt="Woodland Traders" />Our local <strong>Woodland Traders</strong> is a veritable Mecca of consumer goods and hardware. Click map for more</a></li>
  <li><a id="map05" href="#map05"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744924.jpg" alt="Wild Game Diner" />Country living means road kill, and the <strong>Wild Game Diner</strong> prepares it with special sauce. Click map for more</a></li>
</ul>

对于a中的内容我们进行隐藏，我们考虑增加span元素来实现，代码修改如下：

<ul>
  <li><a id="map01" href="#map01"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111743602.jpg" alt="Post Office" />This is the Popsville community <strong>Post Office</strong>, your home of over-priced postage. Click map for more</span></a></li>
  <li><a id="map02" href="#map02"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111743990.jpg" alt="Dew Drop Inn" />Home is where the beer is. And that means the <strong>Dew Drop Inn</strong>. Live music on the weekends. Click map for more</span></a></li>
  <li><a id="map03" href="#map03"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744507.jpg" alt="River Beach" />Spend lazy summer afternoons at the beautiful <strong>River Beach</strong>. Hang out on the nude beach. Click map for more</span></a></li>
  <li><a id="map04" href="#map04"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744638.jpg" alt="Woodland Traders" />Our local <strong>Woodland Traders</strong> is a veritable Mecca of consumer goods and hardware. Click map for more</span></a></li>
  <li><a id="map05" href="#map05"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744924.jpg" alt="Wild Game Diner" />Country living means road kill, and the <strong>Wild Game Diner</strong> prepares it with special sauce. Click map for more</span></a></li>
</ul>

在显示的时候文字会跟着图片排版，为了方便我们对其中的描述文字进行样式调整而不影响图片的布局，我们单独给描述文字增加span元素，代码修改如下：

<ul>
  <li><a id="map01" href="#map01"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111743602.jpg" alt="Post Office" /><span>This is the Popsville community <strong>Post Office</strong>, your home of over-priced postage. Click map for more</span></span></a></li>
  <li><a id="map02" href="#map02"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111743990.jpg" alt="Dew Drop Inn" /><span>Home is where the beer is. And that means the <strong>Dew Drop Inn</strong>. Live music on the weekends. Click map for more</span></span></a></li>
  <li><a id="map03" href="#map03"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744507.jpg" alt="River Beach" /><span>Spend lazy summer afternoons at the beautiful <strong>River Beach</strong>. Hang out on the nude beach. Click map for more</span></span></a></li>
  <li><a id="map04" href="#map04"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744638.jpg" alt="Woodland Traders" /><span>Our local <strong>Woodland Traders</strong> is a veritable Mecca of consumer goods and hardware. Click map for more</span></span></a></li>
  <li><a id="map05" href="#map05"><span class="offset"><img src="https://img.aspxhome.com/file/UploadPic/20075/20075111744924.jpg" alt="Wild Game Diner" /><span>Country living means road kill, and the <strong>Wild Game Diner</strong> prepares it with special sauce.

</ul>
