我正在尝试复制9gag首页只是为了练习。我无法理解为什么我的侧边栏一直在下降。我确信必须有一些简单的答案，但我无法弄明白。

只是给一些边缘到顶边吧..........

答案 1 :(得分：1)

您需要将所有帖子放在自己的容器中，并将所有帖子放在另一个容器中，两者都在您的包装器中。将100％宽度应用于包装器，并为两个容器指定相对宽度，并将主div向左浮动，并将侧边栏div向右浮动。 （如果您希望侧边栏位于主div和屏幕右边缘之间的空格中间，则将它们向左浮动。）

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，但这显示了这个概念。

相关代码：

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

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