上面的代码和css让我头疼，因为如图所示，当我添加图像时，div背景颜色变得混乱。这是动态内容，但我认为显示静态html会更容易。谁能告诉我我做错了什么？背景颜色也应该覆盖图片。谢谢！

修改

谢谢你。这是我以前尝试过的东西，但它没有做任何事情。我也在那里尝试了一个垫片，但它没有做任何事情。狼狈！

Answer 1

您正在将图像设置为向右浮动，这意味着容器div无法计算出它的实际高度。您需要清除浮动元素，它基本上让容器知道图像的实际大小。

您需要在HTML中的img标记下添加样式为clear: both;的元素，最好是在div的末尾，如下所示：

<div id="story">
<div id="individual">
<img src='uploads/1231924837Picture.png'/>

<h2>2009-01-14</h2>
<h1>Headline</h1>
<p>stroy story etc stroy story etc stroy story etc</p>
</div>
<br />
<div id="storynav">
<a href='home.php?start=0'>1</a> 
<a href='home.php?start=1'>2</a> 
<a href='home.php?start=2'>3</a> 
<a href='home.php?start=3'>4</a> 
<a href='home.php?start=4'>5</a>  
<a href='home.php?start=5'>6</a>  
<a href='home.php?start=6'>7</a>  
<a href='home.php?start=7'>8</a>  
<a href='home.php?start=8'>9</a>         
</div>
  <div class="clear"></div> <-- add this here
</div>

添加课程：

.clear
{
  clear: both;
}
