为什么我的侧边栏一直向下？

Question

我正在尝试复制 9gag 首页只是为了练习。而且我不明白为什么我的侧边栏一直向下。我相信一定有一些简单的答案，但我就是想不通。

是的，我需要添加一些文本，因为代码太多了。提前谢谢大家。

Answer 1

您需要将所有帖子放在它们自己的容器中，并将所有旁白放在另一个容器中，两者都在您的包装器中。将 100% 宽度应用于包装器，并为两个容器分配相对宽度，并将主 div 浮动到左侧，侧边栏 div 浮动到右侧。（如果你想要侧边栏位于 div 和屏幕右边缘之间的 space 中间，则将它们都向左浮动。）

请参阅此 fiddle（使用您的代码）作为示例。您仍然需要根据需要更改缩放比例，但这显示了概念。

相关代码：

.main{
  float:left;
  width:60%;
}

.sidebar{
  float:right;
  width:30%;
}

Answer 2

这可以解决您的问题

<div class="wrapper">
  <div class="posts">
     <div class="post">
       ....
     </div>
     <div class="post">
       ....
     </div>
  </div>
  <div class="aside">
    <div class="aside-item">
       ....
     </div>
     <div class="aside-item">
       ....
     </div>
  </div>
</div>

.posts{width:66%; float:left;}
.aside{widht:34%; float:left;}
.post,.aside-item{width:100%;}

Answer 3

<div class="wrapper">
  <div class="posts" style="
    width: 60%;
    float: left;
">
    <div class="post">
        <h3>I know I'm a douche for wearing sunglasses at night but...</h3>
        <img src="http://img-9gag-fun.9cache.com/photo/a77Pzr2_700b.jpg">
    </div>
        <div class="post">
        <h3>I know I'm a douche for wearing sunglasses at night but...</h3>
        <img src="http://img-9gag-fun.9cache.com/photo/a77Pzr2_700b.jpg">
    </div>
        <div class="post">

    </div>
    </div>
    <div class="side" style="
